I have a U-CAN_DO 46 with an OS 50 SX. The problem I have is that in some manuvers and high speed dives I get severe aileron flutter which does stop as soon as I pull back power to idle. I have checked everything for tightnes including the hinges, clevis', servo arms etc. I have sealed the gap between the aileron and wing.
Has anyone experienced this and what was the solution?

Thank You

Craig
