Ryan STA arobatic performance ?
Pat,
It's not an aerobatic plane like an Extra or Cap. It has a small rudder and it has a fair amount of wing dihedral. That alone will limit what you can do. The Ryan can do basic aerobatics, loops, rolls, stall turns, 4 point rolls and limited knife edge. Some of the more advanced stuff won't be all that pretty because you'll be fighting the plane's inherent design as a trainer. As far as spins go it probably will flat spin but I would not be tempted to try it with that plane.
It's intended to be a sport scale aerobatic and it does that very well. I would suggest a purpose built aerobatic if you want that sort of thing. It will make it much easier.
just my 2 cents....
