I moved the CG back and aligned the elevators for equal deflection.

Good News: I did some successful parachutes without the wing drop/spiral. Hover was also improved. Landing was a little like dancing on a bowling ball - the nose came up at reduced throttle.

Bad News: Even with the CG way back, I still needed "up" elevator trim. I decided to investigate some more. At higher throttle she wants to go down. Back off the throttle and she goes nose high. It has to be a thrustline problem. I believe that I have downthrust in the model. I'll get out ye olde incidence meter and see what it says. Sheesh, these things are jig-built aren't they? The thrustline should be spot-on.

I'll report back.
