What does RC Stand For?

If you’re new to RC it can often be confusing just what is meant- radio or remote control cars.  Though the two are often used interchangeably, this is incorrect; they are not the same thing at all, since the way they transmit signals is completely different.  You can spot a remote control car by the wire connecting the controller to the car itself.  Radio control vehicles, on the other hand, use radio frequencies to send messages from the steering controls on the transmitter to the receiver in the car.

There are FCC regulations for all consumer electronics that use radio frequencies, in order to properly allocate the frequencies on the band without too much interference.  Usually RC vehicles operate at 27MHz or 49MHz frequencies- the same as your walkie talkie or garage door opener.  More advanced RC models like planes require a higher frequency, and are regulated to 72MHz or 75MHz.  Always consult your manual to make sure you’re using the correct frequency, and for instructions on how to change frequency.

As long as you’re running your RC by yourself, all you need to do is follow the manufacturer’s instructions on how to choose the correct frequency for your vehicle.  But when it comes to race time or even just practicing with friends, you’ll need to make sure every one has their own frequency or the signals will get crossed.  If you’re at an official race, the organizers take care of this by providing each racer with a specific frequency and a flag with which to mark your car.  In order to avoid crossed signals, you’ll need to make sure when practicing that you follow a similar process.

Getting Started

Just like buying a real car, deciding on an RC car takes research, price comparison and evaluation of your own needs.  Though all RC’s have the same components—transmitter, receiver, motor, and power source—they vary widely in size, type, and degree of difficulty.

The first, most important decision to make is whether an electric or a nitro car is right for you.  Nitro cars tend to be faster and more powerful, though their engines require a lot of maintenance and tuning.  Electric cars, on the other hand, don’t run quite as fast, but they’re easier for beginners and run much quieter.
