I know of a Silent 2 FES that had a prop strike on takeoff. Took an inch or 2 off both props. Pilot continued the launch. Said from his perspective he suspected a strike but the glider seemed to power and fly okay. Motor was fine; don’t even think it required an inspection. Got new props. I’ve watched a FES prop balancing exercise. Looked like it required special equipment and was rather tedious. Anyone have information on that process?
