RE: Great Planes ExtraS
This plane will NOT 3D on standard set up. It will NOT do harriers, elevators, etc . You need to increase the size of the control surfaces significantly to be able to 3D. You also need to reduce weight, mine is at 6 1/4 lb with a Saito 100, I would say you need to get down to less than 5 1/2 lb for its size to get it to 3D well.
It is a great aerobatic flyer for say IMAC, but will not 3D.
