Radio Control Soaring
"I am continually hearing from people who, having read a little about the many joys and delights of silent flight, are eager to start, but are really not quite sure how to go about it. I hope that, in the following chapters, enough background information has been imparted to enable them to embark on their soaring careers with some confidence."

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 ,

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.

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.

Steve & bjrn, thanks a lot for this book because as far as I remember it was the first one I read when getting into the hobby again in the late 1970s. Even though it's about 40 years old it still has a lot of very valuable information. If you can design, build and fly a sailplane, rather than a power plane, then you might understand aerodynamics even better because there's no thrust to directly oppose the drag and to indirectly oppose the weight. Therefore, the main aim should be to decrease the drag as much as possible. One way to do that is to increase the L/D ratio as much as possible by using a higher aspect ratio wing and/or a thinner aerofoil. Another way is to decrease the surface drag as much as possible by smoothing it even more. However, if someone in the Outer Zone thinks that the decrease of weight is more important, as seems to be commonly believed, then please let me know why. Of course, the L/W ratio is what makes sailplanes and power planes aircraft, rather than surface craft, but remember that I’m referring to the main difference between those two types of aircraft. Since this just might begin a discussion, I also wonder why I’ve never read about modellers using wave lift, rather than just thermal lift and slope lift. I'm talking about true wave lift, which God's creatures, the seabirds, use, not the mountain wave lift which full-size sailplanes use. Of course, using slope lift at the seaside is close to that, but it's still not the same as flying over the actual waves of water, which is the only constant source of lift. If a sailplane has an electric power system then that can be used when absolutely necessary in place of the birds' flapping wings to avoid getting wet. No, I haven't done it yet because I'm just getting back into the hobby again, but I will one day, God-willing. So, looking forward to maybe hearing from someone eventually about these thoughts,

I've just read about Power Scale Soaring in the special Winter 2018 issue of RCME. It confirms my emphasis on decreasing drag more so than decreasing weight because those models of full-size power planes have to have the smoothest possible surfaces, which are described in great detail, in order to soar because they simply don't have high aspect ratio wings, except for the models of airliners. Also, the article describes their greatly varying weights for the exact same designs of Hurricanes, which means that the decrease of weight doesn't mean as much as the decrease of drag. Then again, I suppose that almost anything could soar if launched from the Great Orme :)
