Frequency

Definition: In RC vehicles, frequency is the specific radio signal sent from the transmitter to the receiver to control the vehicle. Hertz (Hz) or megahertz (MHz) or gigahertz (GHz) is the measurement used to describe frequency. In toy-grade RCs, the frequency is normally a set channel within the 27MHz or 49MHz frequency range. There is a greater variety of channels and additional frequencies available in hobby-grade vehicles. Each country or part of the world has its own reserved, approved frequencies for use by radio controlled surface and air vehicles.

In the US: 72MHz Channels 11-60 are for aircraft use only. 75MHz Channels 61-90 are frequencies for some surface vehicles (boats, cars). 27MHz (6 color-coded channels) is commonly used in both hobby-grade and toy-grade RC vehicles. 49MHz is found in some RC toys. Use of 50MHz frequencies in RC vehicles requires an amateur radio license.

2.4GHz Spread Spectrum or DSM is being used increasingly for RC vehicles because it eliminates frequency interference problems.

In Australia: 27MHz Channels 10-36 are for surface vehicles. 36 MHz Channels 601-659 are for aircraft and boats. 40MHz is also used by some RCs.

In the U.K.: 27MHz (13 color-coded channels) is used for some RC toys while 35MHz Channels 55-90 are for aircraft use only. Cars and boats can use 40MHz Channels 665-995.
