I had a glow ARF that I put together several years ago. When I put the horizontal stab on, glued it in place, then went to bed to let it set. During the night, it settled so that it was "tilted" to the left. I saw a paw print on the left side.. looked like the cat had walked on it as the epoxy was setting up and stayed that way once it was set.

It flew just fine.. as cutaway said, it tracked slightly irrregularly but it flew fine.
