Why don't airplanes with high lift wings (like flat bottom trainers) have lifting/airfoil horizontal stabs. I would think if the lift and tail moment where calculated correctly once the elevator is trimmed, the plane would fly level at any airspeed, above stall of course. I would think it would make a more stable plane which is idea behind a trianer.
This discussion really has not addressed the OP's concern or goal heighlighted in the above quote. A trainers tendancy to climb under accelleration or higher air speed. This is a product of the main wing's and horizontal stabalizer's reletive incedence and the engine's thrust angle. I feel it has nothing to do with the airfoil, or lack of airfoil, in the horizontal stab. My Funtana X100 has flat stab tail feathers (epanage SP?) and it does not care what speed I fly it at, it goes where it is pointed.
If you, tripower222, are comfortable with your trainer as it is and want to play with it, Try shimming the back of the wing up a little at a time reducing it's angle of attack reletive to the thrust line a little at a time and see what results that produces.
