Barry, I was wondering do you know what caused the flutter? I would think the flutter itself would cause the arm to bend. The only thing bending in flight would do is cause some binding, unless it was so flimsy the arm flexing back and forth enough to cause flutter. You said you moved the bolt to the outside hole to get better resolution, my servo arm only has one whole for the bolt. Is it possible you had different servo arms than mine and Jims? Hate you lost so much money on the crash, I know people say if you have to worry about it you shouldn't be flying it but I have considered just getting rid of mine due to all the problems I have had and now things like this. I haven't been very impressed with the overall quality of this kit.
