Anyone else had stability issues? Twice i have ended up with a track looking like a ball of string, all to easily. The first time i almost got it down in 1 piece with full right rudder and some up (no mods). Second time i reduced the motor thrust line. Take off had a small left turn which went extremely nasty following right aileron input. Total loss of control, but i am very impressed with the small box in which it performed loops, rolls etc. I have flown some real handfuls before, but this is a really wild ride!

Any ideas?
