I'm getting ready to put together this arf with a DA 50.
I have a flying buddy who has one with an odd flying problem.
it trims fine at slow speeds but wants to roll rt. at high speeds.
when you trim it out for high speed then it will roll left at slow.
We don't see a warp or an incedence prob. with the wing.
Does anyone else know of or have this problem? or the best way to find it and fix it?
It sure would help before i start mine.

Thanks,
Chas
