Rudder Gears

3D Printed ABS gears designed to be used for servo driven model ship rudder systems.

The rudder shaft gear has a 1/8" center bore hole and a heat set insert for a 4-40 set screw (included) to secure the gear to the rudder shaft.

The servo gear has a center hole for the bolt to secure it to your servo (not included due to variety) and has a cutout on the bottom for an X shaped servo horn to help secure it.

The 2.5" idler gear has a 1/8" center bore. It is to be used for ships with narrow sterns to help push the servo farther away from the physical rudder shaft position.
