ELECTRONIC SPEED CONTROL (ESC)

NOTICE: The ESC (DYN4925WP) is compatible with NiCd and 

NiMH batteries only. Not for use with LiPo or LiFe batteries.

Programming: This is an auotprogramming ESC. The ESC auto-

programs each time the vehicle is turned on.

SETTING THE GEAR MESH

The gear mesh has already been set at the factory. Setting the 

gear mesh is only necessary when changing motors or gears.

You must remove the vehicle’s gear cover (A) to make this 

adjustment. 

Proper gear mesh (how the gear teeth meet) is important to the 

performance of the vehicle. When the 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. 

Set the gear mesh by following these simple steps:

1. Loosen the 2 motor screws (B).

2. Put a small piece of paper (C) between the pinion and spur 

gears.

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

4. Rotate the gears to remove the paper. The gearing should 

move a small amount.

5. Reinstall the gear cover.
