Radio Frequencies
  Tower Hobbies supports the Academy of Model Aeronautics in its efforts to make R/C modeling safer by reminding everyone that there are specific, reserved channels for aircraft and surface (car/boat) use. Why separate channels? In today’s crowded urban areas, it is not uncommon to find R/C cars being run within radio range of a model aircraft flying site. Without channel separation, the possibility of interference would always exist. Most of the crashes that have occurred were caused by people unknowingly operating on an improper channel and they were also unaware that any R/C flying was taking place in the area. It’s not just an airplane problem - a runaway electric car at 30 mph (or a gas car at 50 mph) is no laughing matter. Remember that our Broadcast Channels were granted to us by the FCC and we are able to obtain and keep our R/C exclusive channels thanks in part to the excellent safety record of R/C modelers. In other words, this channel system is not just an AMA guideline for members, it’s the law of the land that applies to all R/C users. So please, be aware of the aircraft only/surface only channel system. The model you save just might be your own.

Radio Frequencies

Aircraft Use Only (72 MHz)
(72 megahertz, Channels 11 - 60): This is the most popular choice for flying models. Most radios designed for model aircraft and helicopters will be available on these channels.

Surface Use Only (75 MHz)
(75 megahertz, Channels 61-90): Cars, boats, and other non-flying models must use one of these channels. Pistol grip radios are available on 27 MHz as well as 75.

All Uses (27 & 50 MHz)
(27 megahertz, Channels A1-A6 and 50 megahertz, Channels 00-09) While legal for air or surface use, we recommend that 27MHz be used only for surface models. A pilot and driver broadcasting on the same 27MHz frequency would cause interference and could cause a crash. 50MHz channels can be used for R/C, but require the user to attain a Technician-class amateur radio license from the FCC.
