MOTORS AND GEARING
CAUTION: Read before operating your
model with 65+mph gearing!
• The 24/54 ratio for use with 6S LiPo batteries is designed
for maximum speed on smooth surfaces only, with steady
acceleration to full throttle.
• Do not use this gear ratio for general driving.
• Avoid repetitive starting and stopping.
• Do not use the 24/54 ratio with NiMH batteries or low-capacity
LiPo batteries. 5000mAh LiPo batteries are recommended.
• Allow the motor to cool between runs, and monitor motor
temperature.
• Do not use the 24/54 gear ratio for off-road running or
overheating and damage may result.
• Do not allow the motor temperature to exceed 200° F or damage
and motor failure may result.
Adjusting Gear Mesh
Incorrect gear mesh is the most common
cause of stripped spur gears. Gear mesh
should be checked and adjusted anytime
a gear is replaced. Access the gears by
removing the single screw on the top
gear cover.
To set the gear mesh, cut a narrow strip of
notebook paper and run it into the gear
mesh of the motor. The motor is mounted
to an aluminum motor mount.
Loosen the single motor mount
screw with the provided 3mm
wrench to slide the motor
mount. Slide the motor and
pinion gear into the spur gear.
Retighten the motor mount
screw and then remove the
strip of paper. You should be
able to run a fresh strip of paper
through the gears without binding them.
Gearing Compatibility Chart:
The chart below shows a full range
of gear combinations. This does NOT
imply that these gear combinations
should be used. Over-gearing
(bigger pinions, smaller spurs) can
overheat and damage the motor
and/or speed control.
