HPI Wheely King Servo Saver A392 (from set 85260)

Description

Hpi Wheely King Is An Entry Level 1:12 Scale Rc Monster Truck. Its Steering Servo Mechanism Contains A Sacrificial Split Ring Coupling Called A "Servo Saver". When You Hit A Tree With Your Front Wheel The Coupling Breaks And You Get To Buy A $11 Set Of Parts (85260) To Replace Just That One Small Plastic Piece. After Going Through 2 Of Those, I Measured And Printed The Next One. Then A Couple More. A Coupler Out Of Pla Seems To Work Fine. It Holds Up During Normal Use And Breaks On Impact, Just Like The Original Part.
