Is there such a thing as "Dreaded WEDGIE Flap?"

My wedgie seems to 'flap' when I pull out of a high speed dive. I've never heard of that before!

It's only taken a few hits - and they've been very minor. There's no evidence on the outside of any damage - before I strip & re-cover it, I was wondering if they're something I've missed.

It's always flown great, the only change I made was the prop (gunther 5x5 became a Graupner Speed CAM 5x5)

Thanks

maybe just elevon flutter, but yes a wedgie can be made to flap....is the whole wing flapping visably, or are you just hearing a buzz? It's been my experience, that once you get the "flap", you will have no doubt that it is there, no "seems to" about it


Later,
David

The whole wing 'flutters' (almost like a bird in trouble out of an old Bugs Bunny cartoon ) again, only when pulling out of a hi-speed dive.

I solved it in mine by taking the bottom covering off , and adding a carbon fiber spar.
I used a .100 rod.
my second one I added it when I built it.

An inanimate carbon rod! I'll try that!

Thanks!
