Currently, all of my new racers use a fiberglassed skin hinge on the top which is extremely clean.

Using two ailerons, typical movement is about a 1/8" inch. Translated into degrees I would guess that it would be about 5-10 degrees??

I would anticipate that I would need nearly 1/4" movement if I went with just one aileron.

Even though we only make left turns, you still level the plane back off after the turn. So you end up using right aileron just as much as left.

Not to confuse the original question, but would it make more sense to hinge on the bottom of the wing?

Banktoturn,

Yes I fly at Grassfield, and am the current V.P. of the club. We would love to have you up next year to check out our racing (and joining us). Our club racing really took off this year, and we were routinely getting 20-25 racers.

Your comments about a longer chord aileron at less deflection brings about other thoughts. We kinda went away from the longer ailerons a few years back due to flutter issues, but with the stiffer skinned hinges this may no longer be an issue. I think I may give this a try also. Maybe I can go with a relatively long aileron on just the left wing. The added weight would help laterally balance the plane.
