What you are experiencing is normal for this plane. mine does, it all i've seen do it also.

this plane has a sharp leading edge and snaps like crazy. (that's what i like about it)! if it is happening when you don't want it to, you should reduce your elevator throw.

i have not been able to execute harrier or elevator type manuvers with this plane. in a blink it will be on it's back.....
