Precautions

Never touch moving parts.

Never disassemble while batteries installed.

Always let parts cool before touching.

Proper gear mesh (how gear teeth meet) is important to the performance of the vehicle. When gear mesh is too loose, the spur gear could be damaged by the pinion gear of the motor. If the mesh is too tight, speed could be limited and the motor and ESC will overheat.

1. Loosen the two (2) motor screws.

2. Put a small piece of paper between the pinion and spur gears.

3. Push the gears together while tightening the motor screws.

4. Remove the paper and the gears should move a small amount.

5. Reinstall gear cover.
