Hello; I have a Decathlon which I flew with a Surpass 70. We had a terrible time getting this plane flight ready, the local plane gurus proclaimed thatr the wing incidence was wrong, as it was so sqirrely in the air and couldn't be slowed down with out snapping. I tried and tried to fly it like the instructions say but it just wouldn't settle down. We moved the wing dowells down and increased teh wing incidence and shimmed up the gap between the wing and the fuselage and it calmed right down. Now I should say that by the time we did that teh fuse had ben rebuilt a few times and was starting to get a bit heavy, I had knocked the tips off the elevators and the rudder with various landing attempts. It was starting to look pretty ugly too as I had re-covered it after each repair. By the time I had it flying like I think it should fly, it looked terrible. I was embarrassed to bring it out. The landing gear had been straightened so many times it was breaking from metal fatigue. I decided to just hang it up and write it down to experience. Quite a dissappointment after many successes with other Great Planes Models. I just recently took the servos out of it for another project (a pizza box Spad)
