SPEKTRUM 3652 4-POLE 6500KV BRUSHLESS MOTOR (SPMXSM2800)
PRECAUTIONS
• Never touch moving parts.
• Never disassemble while the batteries are installed.
• Always let parts cool before touching.
GEARING
The vehicle is equipped with optimal gearing for 2S batteries. When using 3S batteries, Use
alternate gearing to optimize speed, power and efficiency.
Installing a pinion gear with fewer teeth or a spur gear with more teeth will increase torque
and reduce top speed. Likewise, a pinion gear with more teeth or a spur gear with fewer
teeth will reduce torque and increase top speed. Take care when installing larger pinion gears
as this can "overgear" the vehicle, resulting in an overheated motor and ESC. When testing
different gearing options, pay close attention to the temperature of the motor and speed
control to ensure you are operating within the correct temperature range. If the motor is too
hot, switch to a lower pinion gear and/or higher spur gear combination.
CAUTION: Do not touch the ESC or motor after use or personal injury may result.
Do not allow the ESC or motor to exceed 160°F (71°C). A temperature gun (recom-
mended DYNF1055) can be used to safely monitor the temperature before handling.
CHANGING THE PINION GEAR/GEAR RATIO
1. Remove the screws holding the gear cover in place.
2. Loosen the set screw and remove the installed pinion gear.
3. Loosen the motor screws and slide the motor back.
4. Place the new pinion on the end of the motor shaft so the set screw is located
over the flat on the shaft.
5. Position it so the teeth line up with the spur gear and secure the pinion by tightening
the set screw.
6. Set the gear mesh.

POSSIBLE CAUSE
Battery not charged or plugged in

Transmitter not "ON" or low battery
Pinion not meshing with spur gear
Pinion spinning on motor shaft
Transmission gears stripped
Drive pin broken
Servo plug not in receiver properly
Servo gears or motor damaged
Servo gears damaged
Motor wire solder joint is damaged
Motor wire broken
ESC damaged
Motor over-geared
Driveline bound up
Battery pack not fully charged
Charger not allowing full charge
Driveline bound up
Transmitter batteries low
Vehicle battery low
Loose plugs or wires
SETTING THE GEAR MESH
The gear mesh has already been set at the factory. Setting it is only necessary when changing
motors or gears.
Proper gear mesh (how 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.
1. Loosen the motor screws and slide the motor back.
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. Check the mesh at 3–5 different locations around
the spur gear for a small amount of movement.
5. Install gear cover.
SOLUTION
