adjusting the elevators ( movable Parts ) should be fine as long as you are just matching them... I wouldn't use any trim in the elevators to try and offset the trim in the ailerons. It couldn't hurt to check the incidence on the H stabs and correct it if it's off a ton, maybe a degree or more, I wouldn't sweat less than a degree myself ( a degree between both stabs sides and no more than half a degree off from 0 either up or down on either side). As for the wings, ya got me there. I have no clue as to how you would go about changing the incidence with the wings being pocketed like they are, seems to be a lot of work.
Most of the time I take it for granted that the money I am paying for an ARF plane includes the engineering behind developing the plane and assuring that it is built as the engineers foresaw.

about 50% of the time I get bit LOL
Sorry Ruski31 I kinda covered some of the stuff in your last post also, at least Lee will get the point [sm=72_72.gif]
