It is the gap on the bottom aileron hinge lines. The gap opens up more during a snap. I have it for years on my racing gliders. No ill effects, just a lot of comments.

What do you think makes the screech in snaps?As my Adrenaline does the same thing in snaps and any other fast aileron movment manouver.
I first heard that when a felow competor brought along his Impact and loved the sound of it.What makes it and is it bad in any way?
