Things You'll Need
Instructions
Create a chassis, the main frame that houses the batteries, wheels, remote control receiver and motor. Wood is the most advantageous material to use as it is light and easy to drill. Other options are plastic or metal.
Attach the DC motors to the chassis on the motor mounts. The motors must fall within a range of 300 to 500 RPM. Since the car will utilize a differential turning mechanism, the shafts of each motor should be in line with one another when connected. This allows for the most simplistic steering method by activating one motor while deactivating the other motor.
Mount the electronic speed control and remote control kit on the chassis in front of the motor mounts.
Install the batteries. The optimum batteries are alkaline or zinc carbon type. They should be rechargeable. The typical 300 to 500 RPM motor uses approximately 9 to 12 volts. You can provide more power with a series parallel combination of batteries.
Install two types of wheels: the two wheels in the back for traction and propulsion, and the front wheels for traction and turning. Mount each of these sets of wheels on shafts, locked in place with screws or using masking tape to cover the shaft for a snug fit.
