I've been flying CAP's for a few years now and I'd say that they need more up elevator to hold a TR than any of the other unlimited designs. I believe it is due to the low wing.

I agree with Wayne that you might not be as far back on the CG as you think. Try flying the plane and rolling inverted. How much down elevator does it need? If it is more than just breathing on the stick you can probably bring it back some more. I'd move the CG back a little at a time until it starts porpoising or "floating" with power off (when upright).

The H9 cap will require a great deal of up elevator until you really get the plane in the groove. You might even feel as though the plane is on its back a degree or so before it gets in the groove.

Good luck to you. Hope you find the groove, as the plane is a kick to 3D.
