It should sit on its tail at landing fuel load on the gear. Even with that the elevator is up 2mm or 3...

Sean raised the tail of the stab for incidence, as did I. I used one washer. It helped a bit. 821's might be a bit light, you could be getting blow. I would increase the elevator to a metal servo with 90oz or greater torque in the elevator. If you strip one, it will cost you the plane.

I used max throw with alot of expo. can never have enough elevator when you need to swap ends... to a degree..

Make sure the tail booms are tight and done move too.
