Welcome to the world of CRAPS, I mean CAPS...
I have tried from a Hangar 9 1/4 scale to a 35% Carden, Lanier 28%, SIG and a few smaller sizes and have one word for them:
LOUSY !!!
They all had the same bad tendencies flying and landing; different attitudes with throttle, extreme pitch down with rudder, etc, etc...
Even for a simple hammerhead you have to be on top of it all the time correcting pitch problems. The way I see it, if an airplane needs that many mixes to do maneuvers, the design has to be bad.
They are good for some maneuvers only because of the fact that they are so unstable.
My advice; try an Edge 540, Extra or Lazer 200.
