I'm trying to center my ailerons and not sure what to do. It's a semi-symmetrical airfoil. Holding a straight edge along the bottom shows that the ailerons came mounted a little high - there is a 1/8" gap. If you hold the straight edge on the top of the wing, the ailerons line up. I thought you were supposed to center the ailerons with the bottom of the wing. So should I hold the staight edge on the bottom of the wing, allow the 1/8" gap, and keep the aileron in line with the straight edge, or should I just center the ailerons using the top of the wing, or should I do it on the bottom of the wing and have the ailerons touch the straight edge at their trailing edge? I thought this happened because the ailerons warped with the crazy change in weather we just had, but just realized it's because it seems at some of the hinges the aileron is in line with the top of the wing, and some at the bottom.

Thanks. I've been without a plane for 2 weeks do to bad chain of events (2 crashes) and am about to maiden my Dolphin TOMORROW!!!

Edit: I remember people saying they liked their ailerons maybe up a hair, so I went the line of the top of the wing. Looks good, should be ready for an amazing day tomorrow!!! First low-wing, first tail dragger, and set up with dual rates
