I agree with making a new aileron. I have found it a bit easier to recover a wing if i remove the ailerons anyway, so this might actually be the best way to go on this one. all other suggestions on removing the fuel are good ones as well, but just making a new aileron in this case is the best solution to your problem. I have also used PLAIN kitty litter- NOT the clumping kind! It does a pretty decient job.
