I had an aileron servo lock up in a fully down position on a 3M sailplane that was 1000 feet up and 3000 feet out. It went into a spiral from which I could not recover. When we found the wreck, all servos were intact and worked fine except the right wing aileron servo which was frozen at one extreme. Gears were fine, so I presume it was an electrical failure. Cost me the plane.
