Why don't airplanes with high lift wings (like flat bottom trainers) have lifting/airfoil horizontal stabs. I would think ifthelift and tail momentwhere 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.
I think the answer is ease of construction/cost and they don't need a true lifting stab. Keep in mind that a flat surface with incidence will generate lift, so just because the H-stab does not have a traditional airfoil shape does not mean it is not generating lift.

The point here is to generate enough lift toto pick up the tail more and more asthe planespeeds up changingthe planes pitch the correct amount,therefor not changing the neutral trim of the airplane with airspeed.
I agree it likely is cost. As Gray Beard mentioned its done onthe Telemaster, I have never seen one. I am curious how well it works.
