So what your saying is put tape on one side, flip it over, apply tape. Flip over and [take off 1st tape?] or [apply over top of the 1st tape]. Is there supposed to be a gap between the control surface and the wing? How big? Im sorry, I cant picture this because i tried this and it left a gap in between the control surface and the wing. I suppose this just my unique experience and my mistake. I think someone might have to explain a little plainer if they could be troubled.
