GPM Axial EXO 11T Steel Motor Pinion EX011TS Set  [EX011TS]

Technical overview of the 11T pinion

The EX011TS is supplied as a single 11-tooth steel motor pinion intended for Axial EXO platform installations at 1/10 scale. It is designed as a direct replacement hop-up to engage the motor output to the spur gear where an 11T steel pinion is specified.

Install this pinion when adjusting final gear ratio to achieve the desired balance of torque, acceleration and runtime, or to replace a worn motor pinion. Proper installation requires matching tooth count and module to the selected spur gear and verifying axial alignment on the motor shaft. Ensure the pinion seats fully on the motor splines and is secured with the motor's original hex screw or locking method to prevent slippage under load.

As a steel component, the EX011TS provides increased wear resistance at the motor interface compared with softer pinions, which may influence inspection intervals and compatibility with certain spur materials. Prior to operation inspect motor bearings and confirm pinion mesh under static rotation to ensure consistent engagement without binding.
