50 MHz and 53 MHz are surface and air radio control frequencies located within the six-meter amateur radio band. As such, it is necessary to be in possession of a valid Technician, General, Advanced or Extra class US amateur radio license or equivalent in order to legally operate a radio controlled model on these frequencies.

50 MHz allocationsEdit

• 50.800 MHz -- Channel RC00
• 50.820 MHz -- Channel RC01
• 50.840 MHz -- Channel RC02
• 50.860 MHz -- Channel RC03
• 50.880 MHz -- Channel RC04
• 50.900 MHz -- Channel RC05
• 50.920 MHz -- Channel RC06
• 50.940 MHz -- Channel RC07
• 50.960 MHz -- Channel RC08
• 50.980 MHz -- Channel RC09

53 MHz allocationsEdit

53 MHz is no longer in general use for R/C as high-powered repeaters are now operating on this band. These frequencies are still on the list of AMA-certified frequencies for use in aircraft.

• 53.100 MHz -- Black-Brown
• 53.200 MHz -- Black-Red
• 53.300 MHz -- Black-Orange
• 53.400 MHz -- Black-Yellow
• 53.500 MHz -- Black-Green
• 53.600 MHz -- Black-Blue
• 53.700 MHz -- Black-Violet
• 53.800 MHz -- Black-Gray

What follows is a broader, more technical dissertation on six-meter frequency allocations.
