Well, after getting 10 flights on her, we lost my Kadet today. Flew twice with my instructor and everything was fine, but it was windy up at around 200 feet. The wind was really buffeting the plane around, but after alittle while, it would die down, and things were smooth. On the third flight, I was flying the pattern at around 150 feet, and all of a sudden, the plane pitched nose up to almost vertical. I applied full down elevator, but the plane rolled on over inverted, so I applied up elevator to go ahead and bring it through the loop. As soon as it approached level flight, the wind was gusting so strong it pitched it nose up again. I fought this for about 15 seconds, and then told my instructor I no longer had control. He took it, and immediately, the plane did the same thing to him. He fought it for about thirty seconds trying to get the wings level, but the wind won out, and the rubber bands snapped and we lost the wing. At that point, it was just throttle back to idle and hope for the best. Plane went straight in, and the wing drifted down about 250 yards away. We were both puzzle by the fact that neither of us heard the engine throttle down when he reduced it to idle, and were wondering if maybe we got a radio hit, but who knows. Anyway, as hard as it looked like it went in (burried the engine in the ground far enough that only the tip of the muffler was visible), it really didnt do THAT much damage. It pretty much destroyed the firewall forward, and ripped out my main gear (mine is converted to a taildragger), and the vertical stab broke away from the fuse, but that's about it. The wing came down in one piece, with only one wingtip damaged on impact. Trashed a brand new 900mha battery pack, though. Oh well, that's all part of the game. It really wasnt anyone's fault, just some bad conditions all of a sudden. Besides, it's not IF you crash, but WHEN!! Gotta rebuild now so I can get back up there!
