Default RE: strip aileron flutter avoidance


ORIGINAL: wind junkie

I'd like to be able to dive this baby through speed runs with abandon...

It's basically a scratch build, so I can really search for some good light C grain balsa for the ailerons (which I will do anyway), but is it worth risking flutter for the asesthetics of having a single servo with no exposed linkages? I think I'm answering my own question here.

Please help me decide,
Joe
I like the clean look, low drag and light weight of a single servo.
As mentioned you could shorten the ailerons and have tight stiff linkage.
Stiff ailerons are good but too heavy of wood could be a flutter problem.
The leading edge of the aileron should be as thick or thicker then the trailing edge of the wing.
Do not over bevel and seal a tight gap.
Pin or tape the outer end of the aileron during speed runs if there are signs of flutter.
If done right you should be able to avoid flutter at the speeds you will be flying.
