Gliding contest
I did not build them all, but some of them, and most Suzuki's planes, at different scales (but without changing anything to paper thickness, otherwise the ratio weight/flight area would have risen up dramatically, and you couldn't enlarge the patterns more than twice, not to weaken the plane). I was expecting such a result, large spanned delta wings planes as well as old propeller-powered designs with wingspan fly better. I built a Focke-Wulf Ta 183 doublesized (so wingspan was about 18 inches) after Fiddler's green patterns and a free Mig 15 I found on the web and both flyed well. From Suzuki's website, the F15, the F35 and the Mig29 are faily good at gliding. What stunned me was the rolling of all the Suzuki's Raptors I built, whatever the scale could be and the tuning I attempted at to fix it. Aerodynamics remains somewhat mysterious.
Two years ago, I built a large F15 after Suzuki's pattern, entirely made of sheets o foam, about 1.3 yard large, I couldn't experiment for I crushed it when opening the roof of my convertible car on top of which I let it, just after having being completed. I was puzzling about how to leave it entering my car... and as I was sitting in my car, wondering how I could put it in, I just forgot it was upon my head.... too late! The noise was horrible, and it took some time before I reversed the motion. The roof, I stopped after about ten seconds was not damaged, on the contrary of the plane.
