I have a trainer, j-3 cub, and just got the Mariner 40 ARF that I'm starting to build. I was just wondering how big the gap between the ailerons and the wing should be. It seems to me that they aren't very straight, and towards the end of the wing, I have a 2 mm gap while on the other side, it's only about 1 mm.... is it right and what should the gap be?

Thanx...
