Almost lost my Revolver at Joe Nall. I was letting a friend fly it and shortly after be took off the engine was sounding funny at full throttle so he lined her up for landing. Just before touchdown he lost all control. She drifted in and cartwheeled at the end of the runway. Only minor damage but the ESC was fried. I was using the BEC so when the ESC died we lost all control. Castle Creations ESC.
