27MHz

Definition: In RC vehicles, frequency is the specific radio signal sent from the transmitter to the receiver to control the vehicle. Megahertz, abbreviated MHz (or sometimes Mhz or mhz), is the measurement used to describe frequencies. 27MHz is one of the frequencies used in radio controlled vehicles. There are several bands or channels within a specific frequency that are commonly used and these may vary by country or region.

In the US, 27MHz (with up to 6 color-coded channels) is commonly used in both hobby-grade and toy-grade RC vehicles.

Those frequencies are:

• 26.995 MHz -- Channel 1 (Brown)
• 27.045 MHz -- Channel 2 (Red)
• 27.095 MHz -- Channel 3 (Orange)
• 27.145 MHz -- Channel 4 (Yellow)
• 27.195 MHz -- Channel 5 (Green)
• 27.255 MHz -- Channel 6 (Blue)

In Australia, 27MHz Channels 10-36 are for surface vehicles. In the UK, 27MHz (13 color-coded channels) is used for some RC toys.

In many toy-grade vehicles the specific channel within the 27MHz range is not specified and unchangeable making it more likely that two or more 27MHz vehicles operating in the same area will experience crosstalk or interference. The most common fixed frequency for 27MHz toys is channel 4 (yellow) at 27.145 MHz. RC toys with selectable bands (usually 3 or 6) generally have a selector switch on both the vehicle and the controller that let the operator select a different band or channel (designated by letter, number, or color) so that two 27MHz toys can play together.
