Mary : Scale R/C Modeler 1983/12 December : RCL#2322 : 26/10/2018

I love the advert on page 79 for solid scale model ducks - I don't think they'd fly though.
Daithi : Scale R/C Modeler 1983/12 December : RCL#2322 : 26/10/2018

Many thanks to psh, who has found, scanned & shared the missing pages 57-64 [supplementary file above].
Mary : RCM 1978/01 January : RCL#2311 : 24/10/2018

Sorry Min, we only have the magazine pages that are sent to us.
Mary : RCM 1978/01 January : RCL#2311 : 21/10/2018

Great to see a full scan of RCM including the ads! Lots of info on kits and radios from the 70s that brought back wonderful memories. However, pages 57-64 were missing and hoping they can be added.
Min : RCM 1978/01 January : RCL#2311 : 16/10/2018

Thanks to everyone who pointed out the download for this title wasn't working. I've fixed it just now. Sorry for the delay - I've been at work, only just got home.
Mary : RCM 1981/12 December : RCL#2305 : 08/10/2018

I've uploaded the missing page 164 - many thanks to psh :) It's a separate file for now. I'll incorporate it into the main title file when I have time.
Mary : RCM 1981/04 April : RCL#2257 : 04/09/2018

A disappointed reader has spotted that page 164 is missing from this issue of RCM. Does anyone have a copy of the page they can scan and share with us?
Mary : RCM 1981/04 April : RCL#2257 : 02/09/2018

Thanks to everyone who got in touch about the apparent discrepancy in the RCM series: we jumped from December 1977 to January 1981 this week. I'm afraid we don't have any of the 1978-1980 issues. If anyone out there does, and feels like scanning and sharing them with us, that would be awesome :)
Mary : RCM 1981/01 January : RCL#2237 : 26/07/2018

I'd like to say that "everything we do is carefully planned" and claim credit for this - but it wouldn't be true :)
Mary : Popular Mechanics 1905/04 April : RCL#2221 : 21/07/2018

I recently watched a fascinating TV programme on PBS (UK) about the restoration of a Wisconsin Fish Commission Railway Car: https://www.midcontinent.org/equipment-roster/wooden-passenger-cars/wisconsin-fish-commission-2/ To my amazement, the following day you published Popular Mechanics 1905/04 (Pages 427-430) which featured an original article about these railway cars. Coincidence or planned ??!!
ChrisPinn : Popular Mechanics 1905/04 April : RCL#2221 : 21/07/2018

Sorry, I didn't spot that! I'll ask the contributor if they can rescan.
Mary : Modelar 1991/05 May : RCL#2227 : 13/07/2018

Few pages missing...15 - 18! More detail on that Wilga, please!
Marty : Modelar 1991/05 May : RCL#2227 : 13/07/2018

Hi everyone, apologies for the problems with the November 1977 issue of RCM: 7 of the pages are entirely blank. I'm afraid there's nothing I can do about this, as I don't have the original magazine to re-scan, just the scan as it was submitted to us. If anyone out there has the missing pages and can scan and share, we'll be very grateful :)
Mary : RCM 1977/11 November : RCL#2223 : 10/07/2018

This is fascinating, Chris. I've never heard of a slug as a unit of anything before. Except whisky maybe! ;)
Mary : RCM 1977/07 July : RCL#2196 : 12/06/2018

RCM 1977 July Part B Pages 82 - 84: The article on 'Dimensional Methods in Aircraft Modeling' attracted my attention. When I did my Aeronautical Engineering degree in 1965-68, we used a unit called 'slugs' in the calculation of air density. It was a convenient way of getting rid of the gravitational constant. None of my non aeronautical engineering colleagues ever believed there was a unit of mass called a slug. And surprise, surprise, dear old Bill Carter does his calculations in this article using slugs. Oh the sweet nostalgia !! I make the proposal for one of the 'win a million' shows, that the 1 million question is something like 'what are slugs, blobs, slinches and glugs' ? Go google (or ask the audience or your telephone partner) !!!
ChrisPinn : RCM 1977/07 July : RCL#2196 : 12/06/2018

Hi there! A comment was written in this Profile Pub stating that the page with the usual 5-view was absent. Please find my copy attached containing the missing page [added to site just now]. I am aware that Hippocketaero have a collection hosted but I think this came from a different source, can't remember who. Cheers!
MiguelMorao : Profile Publications No. 086: Siemens Schuckert D III & IV : RCL#2181 : 07/06/2018

Thanks for spotting this, Arnaldo. The scan was submitted to us like this, but I will see if I can find the missing pages elsewhere on the internet and add them to our file.
Mary : Profile Publications No. 086: Siemens Schuckert D III & IV : RCL#2181 : 28/05/2018

Hi Mary and Steve, I am sorry but the usual 5V page at the beginning of the Profile is missing from Profile 86.
Arnaldo : Profile Publications No. 086: Siemens Schuckert D III & IV : RCL#2181 : 28/05/2018

I recently found this reprint of a 1929 pamphlet on How to Build and Fly a Glider by Arch Whitehouse. He covers building the Whitehouse Wasp, which appears to be a copy of the 1926 Lippisch Zoegling or Hols der Teufel primary glider or 1928 Northrop primary glider. With your recent publishing of the 1930s Model Airplane News with articles about learning to fly on this type of glider, I thought this might be a good reference addition to the library. Lately, I'm on a 1920s & '30s primary glider kick for some unknown reason and have been looking up all the relevant period documentation that was published. I've found several, but not all of the Flugzeugbau und Luftfahrt pamphlets (Hefts 11,12,13,14,17&18) from Germany and can't find How to Build and Fly Gliders by Hugo Gernsback from 1929. If any other readers have these on their book shelves, it would be good to get them converted to pdf and archived somewhere for all to use before there's a house cleaning or garage sale and these important booklets from way back then disappear. They're 80 or 90 years old and mostly paperback books. They're importance has a tendency to be overlooked, just like old magazines.
Randy : How to Build and Fly a Glider : RCL#2169 : 15/05/2018

This book is a GEM for a newbie engine builder like me. Thank you RCLibrary!
Bill : Model Aero Engine Encyclopedia : RCL#1996 : 12/05/2018

Hi Mary, about the accident with the Chipmunk, the picture could be entitled "the dying swan". She was Ms Socorro Swan, a Latin actress famous in the series "Incredible Hulk", "Colombo" and the "Romper Room", a child's entertainment tv program [see https://www.youtube.com/watch?v=PyJbGALB31I&t=262s]
Pit_Italy : RCM 1976/08 August : RCL#2127 : 12/04/2018

I was delighted to see within the site a rare book packed with so many informations and working drawings for model engines. All people who contributed each a model engine were personalities well established in the field and I was honoured to see their work also in such prestigious magazines as Model Engineer, Stricly IC, Model Engine World or similar. For those who are no longer among us, we miss You a lot.
Tiberiu : Motor Boys International : RCL#2139 : 12/04/2018

The poor woman on the cover looks like she's had nasty accident with that Chipmunk!
Mary : RCM 1976/08 August : RCL#2127 : 09/04/2018

Thank you Ken for making this available once more. It will be a lasting credit to you and the other Motor Boys.
Steve_Australia : Motor Boys International Model Engine Plan Book : RCL#2122 : 24/03/2018

Thanks for getting in touch Chris :) If anyone out there has a copy of the Dorland they could scan & share - please do! I'll also put a request on the Outerzone 'Wanted' page.
Mary : AeroModeller 1951/08 August : RCL#2121 : 20/03/2018

I just loved reading the August 1951 issue of Aeromodeller as it was one I had never seen before. I was very taken by the article 'Convert the Dorland to Diesel Power'. I tried to track down a plan of the Dorland in my files, but wasn't able to. It must have been published in 1946 as there is a b&w photo of it flying in the October 1946 Aeromodeller and the cover of the November 1946 issue has a colour painting of this attractive model. I can imagine that modellers of vintage models, such as myself, would be motivated to build this diesel conversion if the plan of the Dorland was available. Please keep a lookout for it!!
ChrisPinn : AeroModeller 1951/08 August : RCL#2121 : 20/03/2018

Hi David, thank you for getting in touch & highlighting this problem. I'm afraid this kind of thing happens sometimes. We add the magazines & books just as they come in to us, so the page was probably missing when this issue was scanned by the contributor. Is anyone out there able to scan the missing page and share it with us? We'll be very grateful :)
Mary : RCM 1976/07 July : RCL#2120 : 19/03/2018

There seems to be some pages missing from the second download section. I can’t find p.102 to continue reading the Sunbird feature continued from page 83.
DavidFoster : RCM 1976/07 July : RCL#2120 : 19/03/2018

Hello RCL, whilst searching for Plans for one of 3 Halfax Vintage Aircraft which I am restoring, I came across your Site. There is a Photo of Mr Len Stott on the front cover of the "Catalogue" and pages advertising various Halfax Model Plans and Kits. Marvellous!!! I HAVE THREE OF THE MODELS SHOWN, which were built by my late Grandfather Mr. Cyril Tooby, during his close association with Mr. Len Stott, and the Halfax Model Aero Co. I have Spartan, Flying Minutes and Ventura. They have suffered a little from being stored in the loft for many years, but now that I am retired, I have embarked on restoring them. I even kept some of the original Balsa strips he used as stock. My Grandfather used to build Models for Halfax, and also hand carved propellers for rubber powered models on behalf of the Company. Other associate enthusiasts of my Grandfather's were a Mr. Frank Swire, who owned a Chemists shop in Halifax, and Messrs. Nichol and Brown, who owned a large Toy and Model shop in Halifax. It was in the basement of the Toy Shop where most of the Model building materials were sold, to which I made frequent visits. I have sourced full size plans for Spartan, and Flying Minutes, but had no clue as to the origin of the Glider, until I saw the pages of the catalogue. And there was "Ventura", a full dihedral wing Model with wing which "slot onto" the upper part of the fuselage. What a revelation! Now I just need to see if I can find the plans for Ventura, so that I can fully restore it. Many thanks for your Article, and I hope you find my short story interesting.
MikeBateman : Halfax Catalogue : RCL#1539 : 12/03/2018

I like this! Clearly the work of Gene aka rchopper56. There's a lot of work gone in to all these scans. Nice to see, as Roy Clough is very popular for his quirky designs.
SteveWMD : World of Roy Clough : RCL#2107 : 06/03/2018

Sorry to hear of your problems reading the Air Trails Annual 1943, Carlo. We add the magazines & books just as they are sent to us by our wonderful contributors. We don't have a copy of the original book, so I'm afraid we can't add another scan.
Mary : Air Trails Annual 1943 : RCL#1980 : 14/02/2018

Air Trails Annual (Issue 1943) that you posted in RC Library is very interesting, but unfortunately many pages are not clearly readable, the same for some drawings. Is it possible to place in the site an enhanced scan of the whole magazine?
CarloSoliani_Italy : Air Trails Annual 1943 : RCL#1980 : 14/02/2018

Many thanks David, that's most helpful. Apologies for my mistake, everyone. I have added David's re-ordered version of RCM to the site just now.
Mary : RCM 1975/12 December : RCL#2074 : 24/01/2018

The pages in the last half of the magazine are in inverse order. I have reordered the pages and attach a copy of the PDF.
DavidT : RCM 1975/12 December : RCL#2074 : 24/01/2018

The catalogue presented here is the one printed for the year 1962 when the company was still owned by Mr Glasser. You can see very little use of colour, perhaps because it was expensive to print colour in those days and the catalogue was freely distributed, despite stating that it cost 15 cents!!!
edubarca : Revell Authentic Kits Catalogue : RCL#2021 : 17/11/2017

Oops! You're right Ian, well spotted. I've changed the numbering on this issue and I'll hunt down No. 61. Thanks again :)
Mary : Profile Publications No. 062: de Havilland D.H.9 : RCL#2013 : 08/11/2017

I browse your site regularly and think it’s fantastic! I've just noticed the latest Profile publication should be named 62, not 61 and 61 (the Ansaldo Scouts) is missing.
IanH : Profile Publications No. 062: de Havilland D.H.9 : RCL#2013 : 08/11/2017

I have just noticed that this book takes us to 1000 titles on the RCLibrary shelves - hurray! Thank you everyone who has helped support the Library by scanning & sharing your books, catalogues, magazines, patents etc. You are all stars :)
Mary : Building & Flying RC Sailplanes & Electric Gliders : RCL#2010 : 04/11/2017

I guess that would be my job :) I'll get on it now ...
Mary : Plans Handbook 1: Aeromodelling : RCL#2007 : 02/11/2017

The free plan referred to on the cover is in the Outerzone library as plan id 8948, Stothers.
Stormin : AeroModeller 1939/07 July : RCL#2008 : 02/11/2017

Fascinating. Wonder who will do an audit to see which of the plans included are available on Outerzone?
Marty : Plans Handbook 1: Aeromodelling : RCL#2007 : 02/11/2017

This really is a dreamer's book! I can remember spending hours imagining building all sorts of wonderful planes to be found within. I never ever procured even one plan, remaining steadfastly a kit builder to the end!
NicholasTucker : Plans Handbook 1: Aeromodelling : RCL#2007 : 02/11/2017

I think there are a lot of prop flickers out there, all with oily fingers, who will like this book ... if they haven't already got it and are keeping it quietly for themselves!!!
NicholasTucker : Model Aero Engine Encyclopedia : RCL#1996 : 23/10/2017

Is it just me who thinks Don Dewey look surprisingly like Julian Assange in this photo?!
Mary : RCM 1974/09 September : RCL#1983 : 14/10/2017

Sorry to hear that you find some aspects of RCLibrary such a pain. Most of the titles on RCL are scans sent to us by other people. This is why the file size varies so much. If a file is especially big (usually anything over 40MB) I'll usually try to compress it further. This isn't always possible, as some files are already compressed as far as they can be, in which case I have to split the title into multiple files. All this adds another step in the preparation process, which I don't always have time for. I run this site as a labour of love alongside my 'proper' job! There's also a question of quality ie how far it's worth compressing a file if this results in a poorer quality image. My aim for the library is to save as many of the old-time titles as possible, and make them available for as long as possible. With internet speeds increasing all the time, I tend to err on the side of quality: I'd rather the archive was high quality than full of small files.
Mary : RCM 1974/06 June : RCL#1962 : 03/10/2017

General query rather than a Comment If I could. RCM scans are in the 35~40 mb range Yet the Model Builder ones are 15~20Mb. Both are usually same number of pages more or less. Why? the double size files for RCM.. scans. It's a Bit of a PITA to be honest. It takes longer to download those seemingly Oversised Scans and annoying if trying to download more than the occaissional file.
Anon : RCM 1974/06 June : RCL#1962 : 03/10/2017

I loved the bit where it said the Messerschmitt 110 carried two TONS of bombs. Even with the US 'short ton' that's as much as a Blenheim could carry LOL.
Dathi : Air Trails Annual 1943 : RCL#1980 : 30/09/2017

Thank you, that's most kind :) I've put your version onto RCLibrary just now. Thanks again!
Mary : Profile Publications No. 055: Fokker Dr.I : RCL#1975 : 26/09/2017

The copy of this profile as originally posted had page 5 at the end of the document. I have attached a copy of the pdf rearranged with all pages in the correct order. Great work on both sites!
Skippy : Profile Publications No. 055: Fokker Dr.I : RCL#1975 : 26/09/2017

The trick with Firefox isn't to open it directly but 'save link as' - that way it always works (you were downloading it anyway, weren't you?).
Daithi : Aeroplanes : RCL#1894 : 09/08/2017

Thank you for highlighting this, Paul. I'm afraid this happens sometimes (feels like it's happened a lot recently!). We add the magazines & books just as they come in to us, so these pages were probably missing when this issue was scanned by the contributor. Perhaps an earlier reader cut out the pages to build from? If anyone out there is able to scan the missing pages and share them with us, we'll be very grateful :)
Mary : Model Builder 1973/09 September : RCL#1901 : 17/07/2017

FYI pages 31-34 are missing in the scan.
PaulL : Model Builder 1973/09 September : RCL#1901 : 17/07/2017

Hi Skippy - we upload the magazines & books just as they come in to us, which means this page was probably missing from the paper copy when it was scanned by the contributor. I'm afraid this happens from time to time. I guess the original readers sometimes tore pages out for scrapbooks, bedroom walls, to share with friends, and so on. I know that's what I did in my youth with magazines - I still do! Can anyone out there with a paper copy of this issue possibly scan page 44 and share it with us?
Mary : Model Aircraft 1954/02 February : RCL#1902 : 15/07/2017

I have downloaded Model Aircraft 1954/02 February (RCL#1902} and see there is a photo on page 45 that refers to an article on the facing page. Unfortunately that page (44) is not included in your scan. Was it missing from the publication or just overlooked in the scanning process?
Skippy : Model Aircraft 1954/02 February : RCL#1902 : 15/07/2017

Thank you John, that's useful to know.
Mary : Aeroplanes : RCL#1894 : 13/07/2017

I get blank pages occasionally when I use Firefox. When I cut and paste the link to another web browser it works fine. This also happens with the plans site occasionally.
JohnLeB : Aeroplanes : RCL#1894 : 13/07/2017

The download works ok here and no one else has reported any problems (yet). Might be something at your end? If anyone else is having the same difficulty with this title, please let me know.
Mary : Aeroplanes : RCL#1894 : 08/07/2017

Hi Mary - I've got 264 completely black pages. Is it me or you ?? Best Regards !!
ChrisPinn : Aeroplanes : RCL#1894 : 08/07/2017

I'm so sorry about this. I've got a bit sloppy about checking if all relevant pages are present - my apologies. We're no longer in contact with the person who sent us all the RCM scans (it was years ago, long before RCL was even a twinkle in Steve's eye!). I guess his collection had some pages missing here and there, so he just couldn't scan them. Can anyone out there help with the missing articles? (Some may be on Outerzone, of course. If I get time, I'll have a look.)
Mary : RCM 1973/08 August : RCL#1890 : 03/07/2017

This issue has 40 pages missing, I can understand skipping some advertising, but parts of articles are missing as well. Still love the site.
TedAvey : RCM 1973/08 August : RCL#1890 : 03/07/2017

It is a lovely picture, Stu. I'm afraid I have no idea where you would find the original painting. Does anyone out there have any helpful suggestions?
Mary : AeroModeller Annual 1956-57 : RCL#1887 : 30/06/2017

Hello, I am interested to find the original watercolour of the Druine Turbulent used in the cover of the Aero Modeller Annual 1956-7. It is by J.D.Carrick. Would you have any idea where I could start to find it?
Stu : AeroModeller Annual 1956-57 : RCL#1887 : 30/06/2017

I had this book with red color covers. This is one of my favorite books for single channel model airplanes. Well written and comprehensive information, as well as including Weekender model plan.
LeventSuberk : Introduction to Single Channel R/C Aircraft : RCL#1017 : 29/06/2017

Unfortunately, I do not have that issue but I do know that the missing pages are the Super Kaos plans and you do have the whole Super Kaos article [on Outerzone] archived with the plans at Super Kaos oz5523! That does not help much with the first page of the Pitts article which would be page 26.
Ken : RCM 1973/05 May : RCL#1869 : 14/06/2017

Aarrgghh - another one with missing pages :( Can anyone help complete this issue?
Mary : RCM 1973/05 May : RCL#1869 : 13/06/2017

I noticed that pages 23-26 are missing, which makes the articles on the Super Kaos and the Pitts Special kind of hard to follow. Please keep up the great work!
SimonBlake : RCM 1973/05 May : RCL#1869 : 13/06/2017

I want one of these flying cars!
Mary : Air Trails 1937/09 September : RCL#1864 : 07/06/2017

Hi David - I've just checked and it is slightly strange - thanks for pointing it out! The 4 missing pages have been inserted are at the end of the issue for some reason. Perhaps to allow for one single scan of the plan on pgs 32-33? When I get time, I'll split and re-edit the file. Until then, at least we know where the pages are!
Mary : Model Builder 1973/04 April : RCL#1828 : 03/05/2017

This magazine issue is missing pages 31 through 34.
David : Model Builder 1973/04 April : RCL#1828 : 03/05/2017

Sorry everyone! I uploaded the wrong part B for this title. Correct file added just now :) Thanks to Ted & Nikolay for letting me know.
Mary : AeroModeller Annual 1953 : RCL#1824 : 28/04/2017

Thank you Pit - that's fascinating!
Mary : RCM 1972/10 October : RCL#1820 : 26/04/2017

Oct 1972 RCM doesn't do justice to the blonde cover girl - she was famous and is still alive. She was Gunilla Knuttson (with several variants in the name) and was Miss Sweden 1961 and semi-finalist of Miss Universe of the same year. She emigrated to the USA and became famous for the Noxzema shaving-soap TV spot that was considered very sexy in that period (www.youtube.com/watch). Don Dewey paid particular attention to match the colour of the dress or swimsuit of the models (girls) with the depicted models (airplanes). In that period RCM was considered the modeller's Playboy magazine, and modeller's wives were always suspicious about the contents of this magazine. Most of the cover girls are still around and with the advent of social networks it's not difficult to find them, this is another aspect of aeromodelling research ... But I agree, surely it's not one of the best RCM covers.
Pit : RCM 1972/10 October : RCL#1820 : 26/04/2017

That's the result of the swinging '60s being replaced by the slutty '70s!
Daithi : RCM 1972/10 October : RCL#1820 : 25/04/2017

I have to confess, I really don't like this month's cover picture!
Mary : RCM 1972/10 October : RCL#1820 : 24/04/2017

Thanks for spotting this John! Apologies everyone. I've uploaded the correct file now.
Mary : Model Aircraft 1952/08 August : RCL#1779 : 20/03/2017

Sorry if a zillion people have pointed this out, but although it is indeed the cover and contents of Model Aircraft for 08/1952 shown, the download is the issue for October 1952. I visit your excellent site daily, and chiefly because I long to read the article for the Fidgety Midget - temptingly shown under details, I keep checking the download, but it stubbornly remains the October '52 issue!
JohnW : Model Aircraft 1952/08 August : RCL#1779 : 20/03/2017

Apologies to anyone who had difficulity downloading this issue of RCM. I've replaced the file and downloads should work more smoothly. Thanks to Gerrit and Marty for alerting me to the problem.
Mary : RCM 1972/05 May : RCL#1785 : 20/03/2017

Enclosed find photo of my just completed 1936 Bug from the library website [more pics 003]. Found it in the August Air Trails magazine. A bamboo bender's dream, wing tips, stab tips and all the ribs are bent from bamboo. Weighs in at a hefty 7 grams all up without rubber. Enjoy!!
RandyWrisley : Air Trails 1936/08 August : RCL#1689 : 14/03/2017

I've replaced the file that had missing pages with a complete version of this RCM issue. Many thanks to Harry Kirkland for scanning the missing pages :)
Mary : RCM 1971/08 August : RCL#1722 : 20/02/2017

Hi Andres - sorry about this. I'm afraid we can't fix it, as that's just the way this issue was sent in to us. I guess those pages were missing from the original magazine they scanned. Does anyone out there have a paper copy of this RCM issue? Could you scan the missing pages and share them with us? We'd all be very grateful :)
Mary : RCM 1971/08 August : RCL#1722 : 19/02/2017

On the RCM 1971/08 August PDF file, submission date: 16/01/2017, the pages 31 through 34 were missing. I'm so interested in the BE2E article and plans. I would appreciate if you can resolve this.
AndresAcuna : RCM 1971/08 August : RCL#1722 : 19/02/2017

Fantastic, Daithi! Many thanks :)
Mary : German WWI printable lozenge fabric : RCL#1755 : 19/02/2017

The Old Warden example is a 'restored' one. The only definitive D VII with lozenge fabric is at Knowlton in Canada; it's the only unrestored D VII in the world. There's a good collection of photos of that here: www.aerofile.info/wordpress which also shows the "hier anheben/hier nicht anheben" ("lift/don’t lift here") markings. There's a lot of detail on that that gets overlooked. Unfortunately, the Morell ASI (the anemometer) is missing, but the offset fin and windshield are there (again, often overlooked details, especially the 'cutout' at the bottom right of the windshield). But keep in mind that fabric dyes do fade, especially in the open air. The Old Warden example, while it does use printed fabric (made with modern dyes) hasn't been exposed to the elements. To print on tissue – overlap a sheet of standard paper with the tissue (use a photomount adhesive to 'fix it on the back of the sheet) and just run it through. You may need to join sets to fill an A4 and/or an A3 sheet but any decent graphics app will let you do that.

Great feedback Arnaldo, many thanks. Daithi - any chance of that article?!
Mary : German WWI printable lozenge fabric : RCL#1755 : 18/02/2017

It is an excellent idea, I really liked it. Now I would very much like an article (for lack of a better word) to go with it, explaining how he has printed it: tissue(s) used, printer, technique, etc. Yes, I do remember seeing such articles occasionally in the hobby press, and have a rough idea how it is done but this would not come amiss. One question, if I may. The 4-colour lower surfaces colours seem a little pale when compared with the fabric I saw and photographed at Old Warden - which one is right, I wonder?? Anyway, excellent work - and excellent idea on your part to include it.

The usual problem with downloading is just opening the link. What does work is to right click on it and (in Firefox) 'download as' – this saves the download. PDF files have a tendency not to actually download but to open in the browser.
Daithi : RCM 1971/12 December : RCL#1750 : 15/02/2017

A couple of people have been in touch to say they can't download this issue of RCM. It works fine for us on our PCs at this end, using two different browsers, and we can see it's been downloaded by other people too. But maybe more of you are having problems? If you are - apologies! - please can you let me know, and tell me what internet browser you're using. Thanks.
Mary : RCM 1971/12 December : RCL#1750 : 14/02/2017

You're right about the category - I just forgot! I've added it now. I'm afraid I don't have an answer to your question about page sizes. The scans were originally done some time ago by Zoe Quilter, in another format. Zoe gave us permission to use them, then Bullseye converted the files to pdf & 'stitched' all the individual pages together into a single document. I'm not sure why the page sizes differ. I've always wondered the same thing myself. Maybe it's something to do with what happens to the original files when converted to pdf? Can anyone out there enlighten us?
Mary : AeroModeller 1953/08 August : RCL#1738 : 03/02/2017

Is there an explanation as to why pages have been scanned at different sizes? I think this item should be in the magazine section. Love your sites,
TedAvey : AeroModeller 1953/08 August : RCL#1738 : 03/02/2017

The author of this book was also Captain and Instructor in the Prussian Balloon Corps, which sounds rather marvellous.

Hi Steve. PDF file incorrectly tagged as: ModelMaker_1951_02.pdf. Should be ModelMaker_1952_02.pdf.
Howard : Model Maker 1952/02 February : RCL#1699 : 23/12/2016

Hi there, Thank you very much for posting this magazine. The cover brought back great memories. I went to the Australian Nationals in 1975 as a kid ... it really filled my head with dreams! The cover of "Australian & New Zealand Modellers Monthly", 1976/01, shows Daryl Hartwig with his Hercules. At that time, this model was simply huge (apparently 3- 1/2 meter span) and Daryl said it was the first giant scale, 4 engine r/c model in Australia. I think he said he built it in 1974. He said that he needed to get clearance from the authorities to fly this model. He also said that as there were no plans available, he bought a plastic Airfix Hercules kit and made his own plans from that! Many, many years later, when I was a member of the Riverland Model Aero Club, Daryl still had the model but unfortunately he had developed a medical problem and couldn't fly much anymore. He asked if I could fly it for him "one more time" before he retired it and before he couldn't come to the airfield anymore. I said I would really like to try, so one weekend he brought it out and after checking it over, we fired up the engines which sounded great as they were all tuned via a digital tacho and there were NO MUFFLERS! After final checks, we took it onto the strip. On the first takeoff attempt one engine failed so I aborted the takeoff. After refueling and retuning, we took it out again. This time the takeoff was a success. The climb out was quite good, but turns in either direction left a bit to be desired. The wings would tip stall very easily, even at shallow bank angles. The recovery required a LOT of forward stick + cut the throttles back to idle, then get the wings leveled (with rudder only) and flying again, then smoothly apply power again, and slowwwly start climbing again. This all burned up altitude of course and I began to wonder if I could stay on top of it all. After fighting with it a few times, the Hercules and I seemed to 'come to an understanding' and the rest of the flight was reasonable smooth. I even managed a couple of low passes for Daryl which looked and sounded great! (OK, the low passes were for me to enjoy as well ...) The noise that those 4 un-muffled, in tune engines made was excellent (at least to all the modelers present!) and is a sound I will never forget. After flying around for a while longer, I set up for landing while all the engines were still running. The circuit and landing went fairly well and I even did a fairly smooth, nose high touchdown. One engine failed on the landing roll but at that stage, it wasn't a problem. To say I was a fired up would have been an understatement! Apart from the tip stall issues, the flight went great ... definitely one that will always stay on my list of 'great flights'. Daryl was also very happy and congratulated me on the flight and for getting it up and down in one piece. He told me that in the Hercules lifetime, it had only flown 13 times (mine was the 13th flight), and of those 13 flights, it had gone home "in a bag" on 11 of previous flights!!! WOW, I felt even more privileged to have flown it. I of course thanked Daryl for giving me the opportunity to fly this magnificent model and piece of Australian modeling history. Great job Daryl!!

This is a fantastic book. I tracked one down and bought myself a physical copy (it was NOT cheap).

Many thanks to Eduardo for correcting our error about the origins of the name 'Avianca'. I've amended the description accordingly.
Mary : Historia de la Aviacion en Colombia: Avianca : RCL#1681 : 07/12/2016

Glad to see this book preserved here for posterity. My father had a copy and, having seen an ECC telecommander RC set working in his Veron Marlin boat, I was inspired to read this despite being far too young to understand any of its contents. Nevertheless, it triggered an interest in aeromodelling and electronics that determined the direction of my career.
ColinMill : Simple Radio Control : RCL#1612 : 13/10/2016

*According to wikipedia "Otto Lilienthal (1848-1896) was a German pioneer of aviation who became known as the Glider King. He was the first person to make well-documented, repeated, successful gliding flights. Newspapers and magazines published photographs of Lilienthal gliding, favorably influencing public and scientific opinion about the possibility of flying machines becoming practical. On August 9 1896, his glider stalled and he was unable to regain control. Falling from about 15 m (50 ft), he broke his neck and died the next day, 10 August 1896."

Hi Mary and Steve. Please check the article "1st. Colombian Nationals"! You can see me with John Lennon type glasses as one of the judges!!! [see image above] Those were the days!!! Warmest regards,

Glad you enjoyed this issue, Anon :) I'll do my best to dig up more. If anyone out there has anything similar, we'd love to see it!

More of these please if you can!!!
Anon : Model Airplane News 1935/03 : RCL#1622 : 10/10/2016

Hi Mary. Model Airplane News mag had several suffix near the original title. It happened when the mag changed the publisher/editor. In this case the Gray Band Publishing Co. was succeeded by Jay Publishing Co. in Sept 1932. The same happened when some mag was incorporated by another mag in Europe.
Pit : Model Airplane News 1935/03 : RCL#1622 : 10/10/2016

Looks like MAN was once known as "Universal Model Airplane News"; I'm not sure when the name change took place.
Mary : Model Airplane News 1935/03 : RCL#1622 : 08/10/2016

The 'Marvin Mystery Cannon' ships referenced in the Bill Barnes adventure (page 44, middle of centre column) sounds suspiciously like the Fairey Fantome (Feroce) and even the illustrations are a reasonable depiction of the type. To cap it off, page 5 has a photo of the Fantome's Hispano Suiza with its centre line cannon. Hmmmm....
MartyHillier : Air Trails 1936/03 March : RCL#1613 : 03/10/2016

There was a fashion for 'pin-up' style photos back then on the magazine covers (usually with the guy's girlfriend/wife/sister/daughter holding it). Of course back then PCism hadn't reared its head.
Daithi : RCM 1970/04 April : RCL#1610 : 29/09/2016

Is it just me, or is this month's cover slightly bizarre?!
Mary : RCM 1970/04 April : RCL#1610 : 26/09/2016

I agree, Lorenz, it is very difficult to read this typeface. If anyone out there would like to offer us a translation, I'm sure many people would very grateful!
Mary : Der Bau von Flugmodellen : RCL#1024 : 19/09/2016

Stamer and Lippisch being two of the greatest names in German gliding, this book is a real gem. However it is not only written in German but set in an ancient typeface (Fraktur I believe) which makes for real hard reading even if you are fluent in German.
LorenzMuller : Der Bau von Flugmodellen : RCL#1024 : 19/09/2016

That makes sense - good suggestion!
Mary : Halfax Catalogue : RCL#1539 : 24/08/2016

At a guess Mary, 'Halifax' was already registered as a company (probably the eponymous Building Society) and Halfax was just used to get round that.
Daithi : Halfax Catalogue : RCL#1539 : 24/08/2016

Hi Mary, the model on the cover of the book and Aeromodeller magazine was the "Swallow" by C.E. Bowden, published in his book, Petrol-Engined Model Aircraft (1945). Elliptical wing and white body with red arrows are distinctive features of Col. Bowden designs.
Pit : History of Model Aircraft : RCL#1537 : 20/08/2016

Well spotted, Marty! They appear to be slightly different versions of the same picture by C. Rupert Moore, Aeromodeller's resident artist in the 1940s and '50s. Maybe Bowden particularly liked this image and asked Moore to redraw it for the cover of his book? Does anyone know which airplane it is?
Mary : History of Model Aircraft : RCL#1537 : 19/08/2016

Interesting this copy of Bowden's 1946 book has the same cover as Aeromodeller, September 1940 edition here ... coincidence or not?
Marty : History of Model Aircraft : RCL#1537 : 19/08/2016

"Halfax" was based in Halifax, a town in West Yorkshire, northern England. Does anyone know why the company was called "Halfax" rather than "Halifax"?
Mary : Halfax Catalogue : RCL#1539 : 18/08/2016

I decided to find out more about Miss E.L. Todd: Emma Lillian Todd (1865–1937), from Washington DC and New York city, was "a self-taught inventor who grew up with a love for mechanical devices." The world's first female airplane designer, Ms Todd attracted national attention in 1906 when she exhibited one of her aircraft at the Aero Club of America show in New York [image003 above]. She established the Junior Aero Club of America in 1907, hoping to inspire the next generation of airplane designers. Apparently it was her intention to "lecture every Saturday afternoon at her ofice, demonstrating the problems of aeroplane construction". By 1909 the Club had been reorganised, as Ms Todd was now working full-time on the build of her latest plane [image004]. Didier Masson, the pioneering French aviator, test-piloted the plane on November 8 1910. (Thank you to Pit, Wikipedia and the AMA History Program for the background info.

Hi Mary. A few months back I sent you a black & white photo for outerzone.co.uk of a pair of Orions I took "sometime" at RAF Gaydon [image003 above]. The December '62 edition of RCM&E, page 582, solves the mystery as it was the 1962 'At Home' at RAF Gaydon. I was a family member of Gaydon's RAFMAA (Royal Air Force Model Aircraft Association) and Squadron Leader Corser, mentioned in the short article, ran the model club. As well as the photo I sent you of the Orions, I also took one of a highly impressive Gipsy Moth that could do every manoeuvre in the book. This model is described from page 588 on under 'Jack's Gypsy' (Jack Morton). This was the first scale model I saw that had real grunt and it really impressed me - therefore the photo [image004]. Good gracious it was 54 years ago!! Thanks for closing the circle. Best Regards
ChrisPinn : Radio Control Models & Electronics 1962/12 December : RCL#1431 : 19/07/2016

I was able to find a pic of the one I had, sometimes available on Ebay [image003 above]. While mine was fun, it was pretty much a one trick pony. A push button on the flashlight handle applied power to the rotors and you twisted the handle for forward and back, that's all it would do. I'm sure it must have been a Christmas present back in the day, no way I could have bought one myself. We were so poor we had silent TV. At Christmas time we decorated a stump. My main source of income was picking up discarded soda bottles on the side of the road and turning them in for the 2 cent deposit. A good haul would fill up my bicycle basket.

Oh yes, the infamous Austin timer, an instrument of torture introduced during the Inquisition to punish unbelievers. AMA rules required a timed engine run for free flight events, starting at 30 seconds and getting shorter as the engines developed more power. I never had one of these, preferring the more reliable Tatone clockwork timer, which was actually a modified camera timer. Austins had a tendency to stick, allowing your engine to run until out of fuel and out of sight, never to be seen again. Those who were lucky enough to have their model found miles away sometimes got the remains back, usually water soaked and rusty, from the AMA address tag inside. Believe it or not, these are still available, not for model airplane use though. I ran into some of them in my day job, used as timers on electric locks. The locks were installed on doors as part of a card reader access control system. The fire codes mandated an emergency egress button be installed near the door to let you out if something went wrong with the system. Of course they tended to stick just like the ancient Austins did, never allowing the door to re-lock after the required 30 seconds. We found the fire code required a minimum of 30 seconds exit time before re-locking but there was no maximum, so we installed a switch that would latch when pushed until reset by twisting the button. Of course, the first day all the buttons would get pushed by the cleanup crew, so we had to install buzzers to alert the staff when someone mistakenly pushed the button. The system would send an alarm to the guard desk when the emergency exit was activated, but it all worked a lot better than the pneumatic timer. Austin's main failing was the way it was designed in the first place. When you activated the Austin timer, a spring pushed a plunger down thru an airtight tube until it got to the bottom. A tiny adjustable orifice regulated how long it took the air pressure to bleed down. ANY kind of dirt or dust would clog up the orifice and the whole mess would hang up. Sheet rock dust is what ruined our modern day timers just like the antique Austins.

Yes, this is exactly the one I had, but it must have been produced and sold long before the patent was applied for in 1962, I think I had mine sometime in the fifties. I see some other patents on your site showing foldout paper airplanes, usually distributed free as advertising giveaways. My first one was cut out of a cereal box, all in one piece, then the wings and tail unfolded to make a finished model. A piece of modeling clay held the fuselage together in front and also provided nose weight. Whenever anyone in the family would open a new shirt, I immediately scarfed up the thin cardboard for more models. Surprising how much a cardboard cutout will teach you about adjustments and balance, even airfoils bent to different shapes.
DougSmith : Patent: Electrically Powered Vertical Air-Lift Toy : RCL#1443 : 18/07/2016

Superb! I should make one for all of us, then add a family photo of us wearing them :) [Steve and the boys are not as keen as me on this idea :) ]

I still have this issue, it was the first one I bought after moving back to Birmingham following discharge from the USAF. A quick look through the pages illustrates how far we have fallen in the publishing field since then. RCM actually told you how to do things, not like the product catalogs and reviews we see in the magazines today. The hobby shops don't even bother to stock model magazines now, too much trouble and few sales. When RCM appeared each month, modelers would gather at the hobby shop for their copies, and to discuss the month's contents. When I receive my Model Aviation copy each month, the first item I look up is the double page of other member's finished projects, giving me hope that others still build models. outerzone.co.uk is proof that we're not all assembling Chinese ARFs, that building models is alive and well. I enjoy seeing the pix on your site of projects built from plans on OZ. You might consider adding more pictures from modeler's projects, not just from plans on the site. ARFs need not apply ...
DougSmith : RCM 1969/01 January : RCL#1436 : 13/06/2016

It's all down to the way the original person who scanned the book or magazine decides to scan it. We'd prefer uniformity too, but it just depends on what gets submitted to us. Some of these scans have been floating round the internet for years and the earliest ones often seem to be scanned in a slightly idiosyncratic way. Hope it doesn't spoil your enjoyment too much.

I really like the cover art on this issue. Do you think it's Sherlock Holmes and Watson?
Mary : AeroModeller 1941/05 May : RCL#1368 : 07/05/2016

I had one! Mine wasn't an airplane, but a small helicopter, with a more rigid cable from the handle, about 4 feet from the model. The handle, which you could turn to control the angle of flight, contained two flashlight batteries and a small motor which spun a cable to drive the blades. A small gearbox below the blades reduced RPM and added power. Yes, you could get it to hover by pulsing the switch on the flashlight housing. To tell the truth, it wasn't all that great, once you managed to fly it in a circle and hover around a bit, boredom set in. Mine died a merciful death when old batteries leaked inside the handle....
DougSmith : Patent: Remotely Powered Propulsion and Control [Stanzel] : RCL#1357 : 02/05/2016

Hi there I actually have Book 1, that you refer to. It is titled 'Control-line flying', is published by Percival Marshall, and the Introduction by R. H. Warring is dated November 1948. Interestingly the Introduction starts: "This present book is the first of a series of three". I found this book very useful when I started back into CL flying after a 30 years hiatus.
PaulBarham : Stunt Control-Line Flying : RCL#1338 : 30/04/2016

Hi Mary, the series of R. Warring control-line books is composed of three volumes, 1. control-line Flying 1948 (dated regularly) 2. stunt control-line no date (1948 presumed) 3. Speed control-line no date (1948 presumed)
Pit : Stunt Control-Line Flying : RCL#1338 : 30/04/2016

Glad you liked this book, Nikolay. Re: remote control, it says in the introduction: "In this book Mr. Chu explains in simple language various scientific aspects of model aeroplanes in great detail. As this book is focused primarily on free flight, control line and rubber powered models, readers may feel that it has not much to do with the currently more popular radio controlled models. In reality, this book is still very relevant to radio control, especially for the free flight theory." Maybe that's your answer?!
Mary : Aerodynamics of Model Aeroplanes : RCL#1353 : 29/04/2016

Thank you! Very interesting book. And so all the detail and so clearly written! And what about radio control itself (site is named RCLibrary)?

Hi Mary - just a little bio on Bill Polvogt, illustrator of many RCM covers, like this one. Carl William (Bill) Polvogt, Jr was a well known commercial and cartoon artist in the Golden, Colorado area through the '70s and '80s. He died in 1993. Was a friend of one of the original "Royal Products" guys and was hired to be responsible for all of the "conceptual art'' for Royal (America) products, including insert artwork and posters, box and labeling artwork, as well as any artwork on plans and manuals that were isometric or angle views. However, he had nothing to do with planviews, design, construction drawings or development. Position: art dir., Tech. Publications, Chance Vought Aircraft Co., 1951-54; dir., Chas. B. Russell & Assoc., Dallas, Tex., 1954-. Contributor cartoons to *Sports Illustrated; Sat. Eve. Post* and other national magazines. It's worth reading the small description called "On The Cover" that is usually in the lower bottom of the contents page. You can find the name of many models (intended as girls) and their Miss Something title. Sometimes I find some of them are still around on social network with today's photo.

Hi Mary, I've seen Paul Newell reached your site. Concerning his Singlet booklet, I checked on my archive and I found two Radio Modeller plan book and buyer guides. One is from 1972 and the Singlet booklet is advertised, the second has no date but is prior to 1972 (price indicated is 4/-). In this booklet is advertised the singlet construction articles sold as stapled reprint pages of original magazine's articles. Reprint of the complete feature price was 3s, reprint price of the transmitter article only was 1s. Also in Aeromodeller magazine, it was possible to buy a stapled reprint of pages of radio control constructional articles.

Good afternoon from a sunny Tasmania. Thank you for magnificent resources in the plans section and now the book section. I have just downloaded the warplane special successfully with a minor glitch when part C failed but was successful when repeated.
CliveGriffiths : Scale Models Warplane Special : RCL#1327 : 19/04/2016

Hi Martin - you're right. Unfortunately, it came in like that. Can anyone out there help with a scan of the missing pages?
Mary : RCM 1968/04 April : RCL#1332 : 18/04/2016

Hi Steve, There are 4 pages missing from this magazine, pages 17 to 20 which I would love to see having a fascination for ducted fan models. Hopefully they can be restored. Many thanks for an excellent site. Kind regards
Martin : RCM 1968/04 April : RCL#1332 : 18/04/2016

I'm not sure what the problem is, as the files all download OK at this end. Is anyone else having difficulties? Maybe together we can work out what's going wrong?
Mary : Scale Models Warplane Special : RCL#1327 : 17/04/2016

Sadly, the files will not download. Tried three different computers. Files crash after about 5 or 6 MB. Any other way to retrieve the files?
BK : Scale Models Warplane Special : RCL#1327 : 17/04/2016

Thanks for getting touch, Paul. It's exciting to hear from one of 'our' authors! Your background info definitely helps date the book. As an author, I hope you like what we're doing here on RCLibrary. We want to keep these old titles - and the knowledge they contain - in circulation for as long as possible, accessible to as many people as possible.
Mary : RM Singlet Set : RCL#1081 : 16/04/2016

Just came across your website whilst trying to date an event in the history of radio control. As the author of the 'Singlet' book published by RM Books I will try to help with dating information. The book was a reprint of a series of articles in Radio Modeller magazine and was published when back copies of the magazine sold out. Unfortunately RM Books omitted to date the reprint book. As best I can recall, the articles first appeared around the mid 1960s and I would date the booklet to the late 1960s or possibly just into the 1970s. Hope this is of interest.
PaulNewell : RM Singlet Set : RCL#1081 : 16/04/2016

Sorry there are so many large files for this title. I was unable to compress it any further.
Mary : Scale Models Warplane Special : RCL#1327 : 15/04/2016

The Henley plane was really well-marketed. It sometimes still appears at auction.

This looks like so much fun. I want one!
Mary : Patent: Aerial Toy With Jet Operated Turbine : RCL#1322 : 13/04/2016

Hello Mary, I always download and save to my PC and have not had any trouble before, I repeated the download and everything is fine, all the pages are displayed! It may be that trans-Atlantic crossing, my download speed is about 250 KB/sec max, maybe that was the problem. Anyway all is well, and thanks for your response.
Dhman : Encyclopedia of Model Aircraft : RCL#1316 : 11/04/2016

I built these as a kid, didn't look quite the same but the result was identical. Mine were made from an empty thread spool mounted on a dowel as the axle, with a washer on top to keep the spool attached to the dowel. My prop had only two blades, cut out of a tin can, with two small holes near the center. Two small nails were embedded into the top of the spool, heads cut off and fitted loosely into the prop holes. Wrap string around the spool to provide power to spin the prop, which flies off the two nails into the air. If you adjust the tin prop with very little pitch, it will rise just a little in the air and hover close by until it gives out. More pitch will launch it up to the height of the trees, fluttering down when its momentum has spent. Thicker metal will give a longer flight because of the added weight. Lots of fun for a 12 year old kid......

I'm not sure what the problem is. I've done a trial here and the file downloads and opens fine using two PCs and two browsers. The pages are quite slow to load - could it be that? Are you saving the file to your pc then opening it, or opening it in your browser to read? Sometimes that can change the way files appear depending on your browser (although I've also checked that option here and it still looks OK). We'd always recommending saving the files to your pc and opening it there. No one else has reported a problem yet, but can anyone out there shed any light on this?
Mary : Encyclopedia of Model Aircraft : RCL#1316 : 09/04/2016

There seems to be a few blank pages (77,100 etc,) in part B of Encyclopaedia of Model Aircraft. Am I doing something wrong?
Dhman : Encyclopedia of Model Aircraft : RCL#1316 : 09/04/2016

Thanks Daithi, that fits with my guestimate of c. 1978.
Daithi : Control Line Aeromodeller : RCL#1308 : 09/04/2016

It would have to be about 1977/1978 when Emil Rumpel held the World FAI speed championship title (he lost it following a pile up in the 1978 event in Liverpool).
Daithi : Control Line Aeromodeller : RCL#1308 : 09/04/2016

Does anyone know the exact date this special edition was published?
Mary : Control Line Aeromodeller : RCL#1308 : 05/04/2016

Hi Mary, many thanks for your advice. I tried to download the files by windows, and there the files were damaged. So I tried to use Google and the files were OK. Now I have complete documentation for many new models. I fly with the models which I have constructed. Best regards.
Drahoslav : Best of Wylam, Book 4 : RCL#1273 : 04/04/2016

You're right! I'm such an idiot sometimes. Thanks for pointing it out. I'll change the names rightaway.
Mary : Paul Matt Scale Airplane Drawings, Volume 2 : RCL#1303 : 02/04/2016

FYI: On the "Download Page: Title ID=1303 : Paul Matt Scale Airplane Drawings, Volume 2" page, the three (3) sections of the download are titled "Vol1" but should properly be titled "Vol2". Thank you for this service.
StevePollock : Paul Matt Scale Airplane Drawings, Volume 2 : RCL#1303 : 02/04/2016

I'm sorry you're having difficulties with some of the files, Drahoslav. I've just tested Best of Wylam 4, and both files download fine on the computers here. I can see they've been downloaded from the site by other people & yours is the first problem reported. More details might help - what happens when you try to download the files? Do they download but are unreadable, or do they not download at all? Has anyone else had similar difficulties? Any advice for Drahoslav and/ or me?
Mary : Best of Wylam, Book 4 : RCL#1273 : 01/04/2016

Dear friends there are some damaged files in your site, for instance The best of Wylam Book 4. Both parts are damaged and cannot be read. And Wylam drawings are very good as the base for flying scale models. Could you please repair it?
Drahoslav : Best of Wylam, Book 4 : RCL#1273 : 01/04/2016

Hi, I think you will find that the name of the glider on p41 of Radio Control Soaring is a Super Kema Rcme plans 61.
Kevin : Radio Control Soaring : RCL#1023 : 27/03/2016

Believe it or not, I had one of these, but it wasn't in an airplane but in a kind of helicopter. At that time, early sixties, the U.S. Army was developing a "Flying Platform" with an enclosed prop mounted below the standing pilot who would fly the thing. The WenMac engine had a throttle control in the handle, connected to a rigid wire about six feet long. Throttle control allowed the model to rise, while forward and back was accomplished by tilting the handle. No it didn't work very well, that's probably why I received the model from Scarborough Drug Company, who had a model dept. The pull starter was the only way the engine could be started, buried in the depths of the strange-looking model. I had several of the WenMac engines back in the day, can't say they were ever any competition to the much nicer Cox models. Yes, they would run if you could ever get them started. Most of the WenMacs were installed in plastic models, that's where mine originated, available real cheap a few days after Christmas. I think 50 cents was the going price......

Hi Nikolay - and everyone else who pointed this out to me! I've fixed the error and the file should now download properly. Sorry, I think it was my mistake in using '&' in the file name.
Mary : Radio Control Models & Electronics 1962/04 April : RCL#1247 : 03/03/2016

Hello! Unfortunately I could not open a page: http://www.rclibrary.co.uk/title_details.asp?ID=1247 Mistake HTTP 400. Best regards,

This may be my favourite cover yet. I love the way the female model's very jazzy outfit almost matches the paint job on the airplane model!
Mary : RCM 1967/07 July : RCL#1227 : 23/02/2016

This happens a lot. The cure is simple: right click and 'save link as' and it works every time
Daithi : Control Line Model Aircraft : RCL#1173 : 09/02/2016

Surely this patent will make the modellers smile! Like the lipstick in a lady's handbag, this item is always present in the field box of every modeller. And during their life they bought more than one. It's necessary to give current to the glow plug and start the engine - you can't go out without it. In the beginning it was developed using a common laundry clamp!
Pit : Patent: Connector Clip : RCL#1190 : 02/02/2016

I've just tried it at our end and the whole process from download thru saving to opening works OK. Hmm - not sure what the problem could be. I can see the files have been dowloaded a few hundred times so far and no one has reported a problem. Maybe we'll hear from some other people now. Might shed some light on it?
Mary : Control Line Model Aircraft : RCL#1173 : 25/01/2016

Have tried to download the files Control_Line_Model_Aircraft_A.pdf. Filesize=24769KB] Control_Line_Model_Aircraft_B.pdf. Filesize=27410KB] The files download and open fine onscreen. Problem is when you save them to hard drive when you go to open them you get a message that the file is damaged and cannot be repaired. Anyone else having this problem?
Roger : Control Line Model Aircraft : RCL#1173 : 25/01/2016

Better version of the magazine now uploaded, without missing pages!
Mary : RCM 1967/01 January : RCL#1160 : 18/01/2016

Saw the Barkley patent you posted on RClibrary and thought you might like a pic of the actual item [see image above].
Richard : Patent: Model Airplane Propeller : RCL#1152 : 18/01/2016

Sorry! Someone has pointed out that the Dart III plan and part of the article are missing. I've found both plan and article on Outerzone & will add them to this RCL magazine pdf later today. In the meantime, you can download them here: outerzone.co.uk/plan_details
Mary : RCM 1967/01 January : RCL#1160 : 18/01/2016

I've added the missing pages (21-25) to the magazine. Many thanks to Ray Jennings for scanning and sending them in :)
Mary : RCM 1966/09 September : RCL#1139 : 13/01/2016

OK - new version uploaded, not password protected.
Mary : Model Airplane News 1942/08 August : RCL#1151 : 13/01/2016

We get sent these scans by different people, some of whom use password protect for their own reasons. Agreed, it can cause problems. We've only just become aware of this. Now that we know about it, in future I'll check all files for passwords and if necessary convert them to a password free version. I'll convert this magazine (MAN 1942) later today and reupload it to RCL.

Hi Steve, I wanted to print out the Sunduster article but I couldn't and under "File/Security" it says that printing is not allowed. That's not very helpful.
SimonBlake : Model Airplane News 1942/08 August : RCL#1151 : 13/01/2016

I guess this page was missing from the paper copy used for this scan. Does anyone out there have a copy of page 56 they could scan for us?
Mary : Model Airplane News 1942/08 August : RCL#1151 : 13/01/2016

Hi Steve, This is a great issue of Model Airplane News with three classic models one could build. However, page 56 is missing and it would be useful to have if one is building a Sunduster, which I have been thinking about doing. Please keep up the great work!
SimonBlake : Model Airplane News 1942/08 August : RCL#1151 : 13/01/2016

It's a good question! The person who scanned the RCM magazines and sent them to us didn't scan any pages which only contained adverts. Usually, no 'real' content (text or pictures) is lost. But this time the plan does seem to be missing. Does anyone out there have this issue of RCM? Could you scan the plan for us on page 22-23 and send it to RCL?
Mary : RCM 1966/09 September : RCL#1139 : 07/01/2016

What happened to page 21 through 25 in the latest RCM downloadable issue? I thought that there should be a construction plan along with the article, am I wrong ?
Beppe : RCM 1966/09 September : RCL#1139 : 07/01/2016

The foam tray glider is especially for you, Mary. This is the next step after paper airplanes. When I was a child in the '70s and the first foam trays appeared, I deduced that they could be used for small models and I made a lot of them. Great flyers, my mother always saved the trays for me.
Pit : Patent: Model Airplane Kit [Foam tray glider] : RCL#1130 : 30/12/2015

Ken Willard, my favorite designer back then, he liked small models and so did I. Schoolboy, Schoolgirl, Pageboy, Scorcher and Roaring 20 were all Ken's models I built. My favorite was the Roaring 20 with Pee Wee Cox 020, a little touchy but ran well if you used Cox red can hi nitro fuel. The Top Dawg was essentially a larger Roaring 20. Walter Turner, my flying buddy, built his with one of the first small-servo Orbit systems shoehorned into the Dawg. His Enya 09 wasn't really quite enough, so he drilled out the venturi for more power. It DID have more power on the test stand but wouldn't run on the airplane. Finally he replaced the 09 with a 15 and all was well, if a little heavy. The Orbit was a good radio, as long as you re-tuned the receiver when it was new. I don't know why, but they all were short on range out of the box. I developed a method of "oven tuning" the receivers. With the receiver hooked up to my Heathkit scope on the workbench, I moved the transmitter away from the receiver to get the signal strength down low enough to tune the IF and antenna coils. After a while, the house wasn't big enough even without an antenna, so I put the transmitter in the oven and slowly closed the door opening to block most of the signal. If I could get the receiver to work with the oven door all the way closed, the receiver was ready to go. Ken designed quite a few models kitted by Top Flite, all good flyers. He related his experience at a trade show where he was manning the Top Flite booth when a kid came up with some questions: "Did you design all these models"? "Yes". "And do they pay you for them"? "Yes". " Is that your Lamborghini parked outside"? Ken said in his column, " Hell, I had to look it up to see how to spell it".

This issue was a real classic. I built the Nova, easy to build and flew well. Unfortunately, mine didn't last long because I had the latest and greatest in single channel radio gear, an all transistor Controlaire Mule transmitter, a Controlaire superhet receiver and two Royal single channel servos, one for the rudder and the other linked to the throttle. My McCoy 19 ran well but contributed to the demise of the Nova because of vibration induced RF noise from the throttle linkage. Nobody knew there was such a thing with previous super regen receivers as they weren't sensitive to noise like my state of the art superhet. Nylon clevis hardware appeared later after all the unexplained crashes but it was too late for my Nova. My next model cured the problem with a clevis made from a toothbrush handle connected to the McCoy... In another part of the issue was the Torero, essentially a twin tail Stormer, flew well for one of our club members until he was unable to recover from a spin. Yep, right into the ground....

Having started in radio control with 'helped free flight' to transition to just plain 'proportional' it's pure delight to read every thing I ignored about those magical sets controlling those 'wild' Airplanes ! All this to understand that a well trimmed air model really KNOWS how to fly while you are trying to 'control' it ! Airplanes is still my job today. What a great web site !
