Before the inverted question was asked I put an incidence meter on the airplane and also checked the CG. The incidence was zero on the right and 1/4 degree positive on the left relative to the stab. I looked but did not find the incidence setting in the manual. The CG was 3/4 “back from the wing leading edge at the tip (a somewhat nebulous measuring point). I also flew the airplane the previous day to check the amount of down elevator required when inverted. On low rate there was not enough down to hold the plane inverted. On high rate the elevator seemed to require most of the throw. The airplane tracks level from half to full throttle i.e. it does not climb or sink with throttle setting from half to full.

Something is believed to be wrong but I don’t know what.
