    Application(s): Classic Pattern Airplane

    Comments: Use this servo for my main MK retracts in my Classic Pattern Plane. Flawless. Never had a failure. Set them up properly and they will serve you well. Remember, these servos run 180 degrees and stop. Gear is up or gear is down, nothing in between.
