I'm glad you're flying that plane in the middle of nowhere, at least that way nobody else was going to get hurt. It looks to me like the plane was still tail heavy. Did you see the way it drug the tail around during turns? Classic sign of a tail heavy plane. My guess is this plane also requires a little coordinated rudder for turns as well. Most scale planes do.

Truthfully, a plane that flew like that, should never have been put through those manuvers. It was dangerous to fly in a circle, let along high angles of attack that would force a stall. Looks to me like there were some pretty serious issues with the airframe. Personally, I think it ended the best way it could: as kindling for a bonfire. An airframe that messed up needs to be destroyed before somebody gets hurt.

I'm glad you at least had sense enough to fly it by yourself. If you had brought that to our field, you would have been asked to leave.
