* a cable trimmer
* toy RC car with 4 or 6 AA batteries
* 1 @boardname@ (optionally, another @boardname@ too if you want radio control)

## What's the plan?
## What's our hack plan?
Most toy RC car use 3 small DC motors to operate:
* 1 DC motor for the back wheels torque,
* 1 DC motor for the front wheels torque,
Most toy RC cars use 3 small DC motors to operate:
* 1 DC motor to spin (torque) the back wheels
* 1 DC motor to spin (torque) the front wheels
* 1 DC motor to steer the front wheels
The plan is to open up the RC car, remove the existing electronic controller and replace it with the motor driver
that can control 2 DC motors. We will connect both torque motors to one controller and the steering motor to the other controller.
What we're going to do is open up the RC car, remove the existing electronic controller, and replace it with the **Kitronik** motor driver that controls 2 DC motors. We will connect the two torque motors to one controller and the steering motor to the other controller.
Once the motor driver is connected, we will use a @boardname@ to control it. Another @boardname@ can also be used as a radio controller
for the @boardname@ in the car.
After the motor driver is connected, we will use a @boardname@ to control it. Also, we can use another @boardname@ as a radio controller for the @boardname@ that's in the car.
### ~ hint
Ask friends and family for old RC cars lying around, scout thrift shops and other second hand shops for discarded RC cars.
**Getting a car to hack**
