Aileron/wingtip overlap

[Sig600]

Currently mounting up my wingtips using the piano hinge method. Anyone else have about .25-.50" of overlap between the inboard sections of wing tip and the outboard edges of the ailerons? Looks like I'm going to need to trim quite a bit of fiberglass to get a nice fit...

Aileron/Wingtip overlap

Yes, you will need to trim quite a bit off. It has been a few years but if memory serves me, about 1/2 inch or more on mine.

I trimmed mine back to the aft edge of the wing skin and -- using Darwin's instructions -- made the gap between aileron and wingtip the same as the gap between aileron and flap, which I think was about 1/4." I didn't bother to measure how much I took off.

On the bottom, I just trimmed enough to clear the aileron bracket and to allow clearance of the hinge when the aileron rotates.

If anyone searches this in the future .3" on top, .4" on the bottom came out real nice.

Common Spot for Binding Under Load

I would shoot for at least 3/8 inch clearance. Under load the wings and tips flex, not uncommon for binding to occur if you try to keep this gap too tight.

Good to know, I'll double check the spacing of the gap.
