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.
