i have a quick question about the wall. when i pull full up elevator, one wing always drops and i'd always have to quickly correct with rudder. i cannot get my edge 540 to do a "clean" wall manuver. why does it do this? i dont think it's a lateral balance problem or a problem of unmatched elevator halves, b/c sometimes it'll drop the right wing other times it'll drop the left wing.

i have the same problem doing the waterfall. basically any manuver that requires hard full elevator, the plane will not stay "straight" and would require lots of rudder correction. and it just doesnt look "clean".

any suggestions?

thanks.
