ORIGINAL: Sturtz
Come to think of it ,, after I sealed the gaps in the aileron and elev I was using a smaller prop on my 91FX than the 15x6 I'm using now. Once while I was making a high speed pass I noticed some high speed buffeting. Kinda scary,,, and I bet without the hinge tape and extra ca hinges I would have lost an aileron from flutter.
Shakes,, were you flying pretty fast ?
Not really, but we put it through hell last weekend - blenders to upright flat spin may have been the culprit. I'll check after the blenders today but I think its all good now
I noticed some hinge tape had slipped and allowed air to move through so it may have been flutter that was the cause.
