Comments: Very smooth operation. Speed and strength ratings seem to hold true. Good quality - the house is rugged and the plastic mounting tabs stiff.

December 28, 2010Application(s): Elevator Servos, 26% Pilot RC, Extra-260, 30CC
Comments: Fast and strong. Excellent quality. Enough torque for the elevators, no pushback is noticed. No complaints at all after 2 months of flying. Was able to pick them up on ebay at a good price. They do make more noise than other servos, after all, they are digital. These and 2 1258s are on the elevators and ailerons on my plane with 1.5 Hangar-9 black arms.
