Rudder Chain Drive Sprockets

3D Printed ABS sprockets designed to be used for servo driven model ship rudder systems. These are designed to be used with #25 pitch ANSI chain, most commonly the "Plastic ServoCity Chain" which can be found here: https://www.servocity.com/0-250-pitch-plastic-chain/

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

The servo sprocket 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.
