guy here flys the correx buzz bomb, any fast pass has a flutter to it, does no dammage. as with a sport plane i had, it was strong enough to survive the high frequency low movement flutter. i've flown flunflys with flapping ailerons with not much trouble.
a loose surface in wind will want to move tho, thats why buildings sway and what starts flutter. if you slown down to below this natural point you wont get flutter and it'll just hang at the back doing nothing.
Having flown a 130Mph delta through a 60mph Ganster head on, left my wing tip in his foam wing then took out the entire left side of his tailplane i can say anyplane that still has at least half a working elevator can land with no troubles as we both did, my damage was the wingtip only so my elevons were fine. now loose elevons, thats trouble!!!!! but i've seen a Rapier land with one elevon only!!!!! the other controled roll until it's glide path brought it to ground.
