Ok, I did all the trimming routines, and it appears that I need to move the CG back and add right thrust. Drops when inverted, pulls out of dive, yaws left on vertical line, 1/2 right rudder on take-off, corkscrew loop.

Problem is, it seems to need quite a bit of both even though the CG is 1/4 inch behind nominal and it already has small amount of right thrust (GP Extra .40, Saito 72).

Is this normal? What should be the correct settings for non-3D aerobatics? Meanwhile, I'm going to adjust it bit-by-bit until it flys right.
