Rudder sprockets 1.0

These sprockets are an inexpensive way to hook up a rudder in a small space. The servo sprocket fits on the small wheel that comes with a Hitec HS82MG. Two very small screws #0 x 1/8" hold the sprocket to the servo wheel. The rudder sprocket fits on a 1/8" shaft and is held on by a 4-40 nut and screw. To complete the setup you need lamp chain from Walmart (Mainstays brand) and an extension spring ~ 1/4" long. Keep the rudder and servo approximately 4" apart to give plenty of room for the spring and chain ends.
