Dennis,
Get an incidence meter and set the pitch thrust to zero. (up/down)
Try test 2 again.
If it still drops the nose, then you are nose heavy.

I was helping a friend Sun. with a new h-9 Cap. It has a DA 100 and during the flight we tried a few tests. The following happened. (1) Flying inverted the nose would drop fast if you let off the elevator. (2) Climbing at a 45 and go inverted the nose dropped again. (3) flying into the wind at full throttle and going to idle the nose pitches up. Any ideas on balance or engine thrust? Dennis
