Wing Surfaces on the Stuka...
 

I think this is a big problem guys have with this plane. Not that I had it, but, I paid "Big Time" attention to angel of attack and alignment with the wing / air..flaps ..etc. With the under-slung aileron and flaps a guy can get things going in all directions. The way they are set is not the best if not paid attention to.
A few guys where I fly didn't like this plane because the ones they saw ........went .....UP----and Down.. Due to the above reasons.

If done rite this plane is a Nice Flyer..
