I've been flying my LT-40 for about a month on my own. I understand that a flat bottom trainer like the LT-40 will have greater lift at greater speeds. If at all possible I would like to prevent this as much as possible. It actually pulls it self out of a dive. I've played with the trim and if I were to add more down trim, the plane would dive very quickly at low speeds.

Is there a happy medium - would I get the effect I'm looking for if I add a some space where the rear of the wing meets the fuselage, therefore, lowering the angle of the LE?

Any suggestions?
