to radio-controlled vehicles
Radio-controlled (R/C) vehicles
Radio-controlled vehicles should not be confused with remote-controlled vehicles (vehicles controlled with a transmitter attached
to the vehicle by a wire). They are controlled with a handheld transmitter that is not attached to the vehicle but communicates
through radio frequencies. R/C vehicles therefore have much greater range and flexibility.
Just as a radio station broadcasts on a specific radio frequency that you can tune into, a R/C transmitter sends radio frequency
signals that tell the vehicle how to perform.
The signals are sent to the vehicle's receiver on one of the frequencies below:
• 26.96 - 27.28MHz - general use
• 40.66 - 41.00MHz - surface use only (cars and boats)
• 458.5 - 459.5MHz - general use
• 35.305 - 37.945MHz - air only
In order for two R/C vehicles to be operated at one time and in the same area, they must operate on different frequencies. It is
not possible to change the frequency of a vehicle unless it is a more expensive item that has a removable frequency band crystal.
Some larger items have a removable frequency band crystal that can be changed to allow the vehicle to operate on up to six
different bands within the 27MHz frequency. This allows for competitive racing of up to six different vehicles.
