RE: Ultra RC 87" Yak Build and Fly
As far as the stab tube alignment. I found when I had the tubes in they were slightly off, but when I screwed the stab tight to the fuse it looks straight to the wing tube.
My wing had a big twist in it that made the maiden flight horrible. The wing root was at 0 incedence and the wing tip was plus 3 on the right side and -1 on the left side. This was a very easy fix, just twist the wing by hand and shrink the covering back to hold it in place. It took two tries to get Zero incedence. About 15 minutes of work.
I am taking it back out tomorrow to try again.
