Thanks Howard, well spotted! I've edited the file name and it's correct now :)
Mary : Model Maker 1952/02 February : RCL#1699 : 23/12/2016

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."
Mary : AeroModeller Annual 1968-69 : RCL#1626 : 12/10/2016

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,
Eduardo : RCM 1970/06 June : RCL#1624 : 11/10/2016

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!
Mary : Model Airplane News 1935/03 : RCL#1622 : 10/10/2016

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.

Mary : Model Aeroplanes And Their Motors : RCL#1137 : 20/07/2016

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.
DougSmith : Patent: Circuit Control Device : RCL#1479 : 18/07/2016

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 :) ]
Mary : Patent: Toy Airplane Headband : RCL#1469 : 12/07/2016

Head band plane: I couldn't resist. Mary, make two of them for your boys, sorry three, one for Steve too. Be free to make one for you, of course.
Pit : Patent: Toy Airplane Headband : RCL#1469 : 12/07/2016

This is the same concept as the Bat Orthopter I liked so much, but an electric version. The times they are a'changing ... but not so much. Fun is timeless :)
Mary : Patent: Flying Toy Able to Move by the Flapping of Wings : RCL#1462 : 08/07/2016

Our contributor sent us this patent "especially for Doug Smith, who seems to have had many of these vintage patented toys in his childhood." Did you have this one, Doug? :)
Mary : Patent: Electrically Powered Vertical Air-Lift Toy : RCL#1443 : 28/06/2016

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.
Mary : Model Airplane News 1959/06 June : RCL#1429 : 09/06/2016

Hello again, I have just downloaded the MAN 1959/06 issue and I have a question. Why are some pages scanned at a different scale to others? In this issue, as in others, two adjacent pages of a model plan have different sizes, why? Thanks.
TedAvey : Model Airplane News 1959/06 June : RCL#1429 : 09/06/2016

RCM July 1968: I've replaced the previous file with a better one that includes pages 19-24. Many thanks to Rudy for scanning and sharing the missing pages :)
Mary : RCM 1968/07 July : RCL#1366 : 07/06/2016

Thought we'd have a model car mag today - because a change is as good as a rest :)
Mary : Model Race Cars 1948/05 May : RCL#1414 : 01/06/2016

Thanks for the feedback, Bargle. Sorry to hear of your difficulties, but glad it usually works out in the end. Not sure why this happens with some files but not others. It may be due to differences in the way files are first saved by the people who send them to us. Will keep investigating.
Mary : Control Line Model Aircraft : RCL#1173 : 30/05/2016

I've been having this trouble as well. What's happening is the download is going along, then suddenly stops before completion though my download manager shows it as complete. No idea why. Downloading again usually works.
Bargle AKA Butch : Control Line Model Aircraft : RCL#1173 : 30/05/2016

A flying submarine sounds like something James Bond would have! Has anyone ever actually seen one of these - and did it work?

A realistic flying bat toy - brilliant!
Mary : Patent: Orthopter [Bat] : RCL#1393 : 21/05/2016

I've just noticed that this issue is printed up as "Volume 6, No. 7", but is actually Volume 5, Number 9. Does anybody have any idea why?
Mary : RCM 1968/09 September : RCL#1384 : 20/05/2016

Added missing pages 29-31, thanks to RFJ (via RCGroups here)
Mary : RCM 1968/06 June : RCL#1358 : 20/05/2016

Thought we'd include this model boats handbook for a bit of a change. Hope no one minds!
Mary : Model Boats Plans Handbook 1985 : RCL#1386 : 17/05/2016

Yes please Rudy, that would be fantastic :) Many thanks.
Mary : RCM 1968/07 July : RCL#1366 : 07/05/2016

This scan is missing pages 19 - 24. Would you like these missing pages? I can scan my issue copy, and email you these scans in jpg format. Will this work for you?
Rudy : RCM 1968/07 July : RCL#1366 : 07/05/2016

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)?
Nikolay : Aerodynamics of Model Aeroplanes : RCL#1353 : 29/04/2016

Fixed it :) Fourth file added - part D. Thanks to BK (aka The Electric Book Company) and his website therealmidori.com

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.
Pit : RCM 1968/04 April : RCL#1332 : 21/04/2016

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.
Pit : RM Singlet Set : RCL#1081 : 21/04/2016

I've revised it to c. 1948/49, to be on the safe side!
Mary : Stunt Control-Line Flying : RCL#1338 : 21/04/2016

Hi Mary I have this book and I dated it 1948, read page 174, on 133 page there is a prevision.

Modellers' Monthly April 1974: I'm not 100% certain the pages are in the right order, as they're not all numbered. The articles seem to make sense as you read thru, but let me know if you spot any anomalies.
Mary : Modellers' Monthly 1974/04 April : RCL#1336 : 20/04/2016

Help! I can't get hold of the person who originally sent this RCM to us. Has anyone out there got a paper copy of the issue, and would you be wiling to scan the missing pages for us? We'd be VERY grateful :)
Mary : RCM 1968/04 April : RCL#1332 : 19/04/2016

Also missing page 73 and partial article for boat Snoopy.

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.

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.

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.

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?

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......

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!

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?

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 ?

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....
DougSmith : RCM 1963/12 December : RCL#1104 : 12/12/2015

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 !

I've really enjoyed seeing those old issues of RCM, some of which I never saw while I was away at boot camp with the USAF. RCM was such a revelation when it first appeared in Oct of 63, so far ahead of all the other magazines, it was R/C only. They're the reason I got into electronics, believing I could build my own radio with a little schooling. Of course I had no money for school but the US Army at the time was offering a guarantee of whatever school you chose if you passed the test and enlisted for three years. I passed and chose the Army school at Ft Monmouth New Jersey, however, when they found out I was color blind (slightly) they rejected my application. The USAF had a similar program but you had to commit for four years. I was prepared to argue my way past the color test with a pocket full of colored wire to identify but I lucked out and they never tested me. I made a living for years in the electronics field and it's all because of RCM, still build occasional projects, latest is a 4 channel audio amp for a friend's wedding chapel. Most of the parts came from my extensive Get-Me-Outa-Trouble box. But I never did build that radio after realizing how hard it was to find all the parts.....This '66 issue seems to be one of the first appearances of MonoKote, and it was NO GOOD. The glue was different, sticky to the touch, ironed on like you would expect but it wrinkled up like a prune after exposure to the sun. Top Flite later changed the glue and it's been the same ever since. It was expensive then and it still is, known as "MoneyKote" back in the day....
DougSmith : RCM 1966/05 May : RCL#1092 : 07/12/2015

It was interesting to see the 1943 patent for the Guillow's paper airplane. As kid in the 50s, I built LOTS of similar designs, although somewhat simpler in construction. Don't know where the plan came from but construction was so similar it had to come from the same idea. I found a great stack of discontinued sales flyers in the nearby grocery store trash bin that provided a treasure trove of paper plane material. All of then flew, some better than others, most needing a bit of clay in the nose. Amazing how much you can learn from tiny paper planes. I was sorry to see Comet fall by the wayside, I always considered Comet kits far superior to Guillows, at least at the time I was building them. I built many Comet kits but only one Guillows and it was too heavy to fly. Guillows kits were die-cut instead of the Comet printwood, that's why they cost twice as much. But to me, printwood worked much better than the crushed Guillows balsa, just cut it a little big and sand to the blue line, perfect parts. As for stick and tissue kits, Easybilt Models still makes a large selection of stick built kits, probably a small operation but more like the Comet designs....

Mary : Great Paper Airplane Book : RCL#1088 : 03/12/2015

Hi, This is a fabulous idea you have undertaken with this library. Thank you so much for all the work here and with the plans as well. I purchased this book when I built my first plane, a Craft-Air “Drifter” sailplane its wing is still sitting on top of a bookcase even is the fuselage has “gone missing". I also still have the original box for this kit as well as my original Futaba FP-4NLG AM 4 channel radio (also in its original box). However, that’s really a different story. What I wanted to say is that I loaned this book to a friend about 30 years ago and have not seen it since - he is no longer my friend! But now, thanks to you guys, if I ever see him again I can tell him that his theft is forgiven for I now have a digital copy from RCLibrary. Cheers from a very happy if not terribly skilful modeller.
JonO'N : Radio Control Soaring : RCL#1023 : 02/12/2015

I think Paul Newell is still around, in 2008 he said that some years after this booklet he wrote the first edition of 'Theory and practice of model radio control'. Here's Paul's comment in 2008: "I well remember the early copies of RCM&E. I was always an aeromodeller, competition free flight with moderate success but R/C took me into an electronics career. Working with Dave Hughes and Norman Butcher at 'Radio Modeller', I designed the 'Singlet' single channel outfit which was kitted through the local model shop in Woking. Later I wrote a book 'Theory and Practice of Model Radio Control' which was published by RM in the 1970s. The 'Microtrol' homebuilt proportional outfit descibed was kitted by a number of suppliers. Many of the illustrations in the book were prepared by Peter Holland, a former editor of your magazine. I also designed receivers for 'Climax' in Weybridge and eventually set up an industrial electronics company with Peter Cabrol, one of the directors of the company producing Climax. RM also published some of my model designs and these can still be found in the X-List Plans directory..."
Pit : RM Singlet Set : RCL#1081 : 01/12/2015

The book was reviewed in Radio Constructor in June 1971. I think decimalisation was Feb 1971, so the book was published sometime between those dates.

This book is a treasure for me because it has Vic's autograph. He sent it to me way back in 1965!! When I was starting my aeromodelling career I subscribed to Aeromodeller. After a few years, and after building and flying several of his fantastic models I decided to write to him because at that time (1965) he published this book from another company (Foyles) and not by MAP so I did not know where to order a copy [Eduardo is from Colombia]. He graciously offered me to buy one for me and send it via Air Mail. I sent him the money and he autographed it before he mailed it!!! It was a wonderful surprise. I have very carefully kept this book with my most dearest objects.

While perusing Carl Goldberg's article Bring Them Down Safely in Air Age Gas Models, the young modeler who volunteered his Interceptor to demonstrate the dethermalizer, Hershey Goldenberg, was my dad. Although my dad is long gone, seeing him brought a great big smile to my face. Thanks so much for the memories!
JeffGoldenberg : Air Age Gas Models : RCL#1040 : 16/11/2015

Just a short note to say that I was so pleasantly surprised to read the Comet catalogues. My uncle, Sam Goldenberg, was one of the original partners and both he and my dad told me many stories about the good old days. In fact, if memory serves me correctly, my dad, who was just a kid during the company's heyday, was the inspiration for "the Comet Kid." Although both Sam, my dad and to my knowledge all the Comet family are long gone, seeing him mentioned in context as well as all the Comet catalogues and plans brought a great big smile to my face. Thanks so much for the memories!

Dear Sir , I am enthusiast of your community . Through one of the published books 'Radio Control Soaring' on your site I have found an elegant power assisted sport and aerobatic glider [see page 41 for full page BW photo; spec is 72in span, AUW 43oz, pylon mounted .049 engine] . But unfortunately I couldn’t find the name of this model . I have searched the internet even by its specifications as reflected in the book . Also I have tried to find its name through the vague name on the aircraft wing in the image ( it was something like **beria I could find but not helpful .I have enclosed the image of this masterpiece for your information . As result of my obsession , I am determined to construct this wonderful model and hence I am keen to find its name and its plan in case of possibility , but I don’t know how . Hope you can assist me by your kind direction and information . With my best regards ,

The Aeromodeller Pocket Data Book was my bible growing up. My father bought it for me when I started designing my own control line models. Unfortunately, when I moved out and my parents moved, I guess it was thrown out with a whole bunch of other superfluous materials. Thanks for bringing this back into my memory again - many fond memories of my father and I joining the Heswall Model Aircraft Club and flying (or rather trying to fly) small controlliners at the Gayton Playing fields. Ah - happy days.

Super V-Shark seems to be the final candidate for his rounded nose. In Aeromodeller mag. circa 1946 appeared the advertising for this model in the same perspective image. I think they simply copied and coloured the image for this cover.
Pit : Petrol Models : RCL#1004 : 05/10/2015

Steve, I think I've found the correct one with identical color scheme too! It's a Tethered Victor Stanzel Kit (the father of U/C before the Belcrank) - Tiger Shark Speed Demon. In your site you have the Stanzel Super G Shark that has a different undercarriage, but the Tiger is identical with the same rudder shape, just a pointed the nose spinner.
Pit : Petrol Models : RCL#1004 : 05/10/2015

Great cover art. I love this painting. I'm assuming the model shown is fanciful, but maybe I am wrong (that happens sometimes) - does anyone know or recognise this as a real model, and if so do you have any more details?
