Changing the motor in an electric RC is a fairly simple modification. You may need to change the motor because the old one is dead. Or, you might want to get a more powerful motor or get more torque
from the motor. If you are going for more torque you will want to add a smaller pinion gear to the motor. A smaller pinion gear will cost you some speed so keep that tradeoff in mind.
To replace the motor on your electric RC you'll need:
- Small hex wrench
- Phillips head screwdriver
- Tire lug wrench
- Quick-connecting terminals or soldering equipment (see Step 6)
- Electric RC Motor
This step-by-step tutorial shows a motor replacement on the Traxxas Electric Stampede Monster Truck. The process will be the same or similar for any hobby-grade electric RC car or truck.
