I flew yesterday in 20-25 mph cross-winds, and the aft c/g may have been causing it to wander a bit...or could have been the gusty winds.... I may just move the c/g forward a bit in windy conditions and trim for it.
Gary,
Have you checked wing and stab incidences? Don't accept the factory settings. Start with things verified true then go from there. Also make sure ailerons and elevators track true
On pitch couple, did you mean % rather than degrees? 7 to 10 degrees down is huge. If the model pitches up with top right hence needing that much down ele, you may want to reduce incidence of the left panel about .2 degrees. Assuming that the plane has wing adjusters of course.
you want calm conditions for better eval.
