i just reread your post, as to understand what you are saying, now i know what you said.  i may have to clarify what happened, and more than likely, what i think happened, since it is very much possible that i am wrong.

What i believed to have seen, while plane completely lost control of ailerons, was that the wings were "flexing" or vibrating up and down, and making a terrible noise, as the ailerons were "flapping" up and down.

but now, it makes sense to me:

what happened was that when servos were stripped, the ailerons were not "attached" to a servo, so they began the up and down movement.  since they were doing this, this was then transmitted, via hinges, to wings, and then the wings were doing it as well.

this is what i referred to "flutter" of the wing, as this is what i saw, which was way strange.  but in reality, after understanding it, the ailerons had way too excessive unopposed "flutter" that was then transmitted to the wing. 

kind of like if you placed a streamer on the side mirror of your car, and at low speed, maybe the streamer would fluctuate around, but at high speed, then the mirror will begin to "shake"
