Description
The MST NS High-Torque Servo Saver is a great option for a variety of applications. The multi piece design includes 23T and 25T splined outputs, and is combined with the short 16.5mm length horn, or the long 17.5/21.5mm length dual hole horn, and either the red (soft), gold (medium) or silver (hard) spring to adjust the servo saver tension.
