When the RC frequency spectrum was first introduced to provide controlled facilities for radio control (RC) modelers, it was limited to a set of just six. These frequencies were not labeled with channel numbers as they are today, but were represented by multi-colored flags; purple / white for 72.320 MHz (megahertz), red / white for 72.240 MHz, etc. Having only 6 frequencies to choose from was quite restrictive and meant that many RC airplane pilots had to be on the ground, waiting for their turn on a certain frequency. The frequency spectrum of the RC model airplane is much broader today, consisting of 50 separate 72 MHz channels exclusively for model airplane use in the US, some 27 MHz channels for park travelers, and a handful of others. more specialized channels reserved for licensed radio amateurs. In UK, the frequency is in the 35Mhz range and you need to check the assigned frequency range in your own country.
So now that you have decided to buy your RC model and radio equipment, you also need to decide what radio frequency you are going to operate with. Unlike most other sports functions, choosing a popular channel that is used by many other people is not a good idea. Choosing a standard 72 MHz frequency for your radio can be as simple as going to your local hobby store and buying one with a standard radio setup. But choosing a channel at random can be a problem if you don’t do your research first.
First, decide whether you are going to be a park traveler using 27 MHz or opting for a more advanced setting at 72 MHz. The 27 MHz channels are primarily dedicated to those who consider themselves “park travelers”. These prepackaged systems generally come with everything you need to get up and fly and are intended for the casual traveler who just wants to get out, fly, and not mess with the higher cost of a more complex aircraft and radio setup. . Choosing an RC model airplane park steering wheel package with a preset frequency requires little to no research as you have few options as the packages give you the option of only 3 or 4 channels, some FM (frequency modulated). , some AM (amplitude modulated).
Channel conflicts in an RC park flight situation are less common due to the large number of parks and flight areas available to the casual pilot. But if you invest in a park steering wheel, be aware that there may be other pilots in the park using the same frequency as you, and that can spell costly trouble when you lose control of your plane due to someone else’s signal. or even worse, if some stranger accuses you of causing the crash of their plane.
Second, if you are going to use 72 MHz, visit your airfield and find out what other people are using. Imagine arriving at the airfield of your favorite RC model airplane only to find someone else already using the channel you just paid good money for. Some clubs have rules regarding what happens in this situation. As only one pilot can operate at a time on a given frequency, this generally means that pilots have to turn off and take turns using the frequency, and some means for the club to control the shift process, either by physically taking control of the transmitter or simply having a written procedure in the club’s rules. If you are flying in a crowded place that is not a licensed flying club with rules and bylaws, you may be sitting down and unable to fly during the day.
The smartest way to choose an RC frequency for your radio is to do a little bit of groundwork. Visit the field where you will be taking most of your flight. Research which channels are already in use and which channels are used infrequently. Finding one that is infrequently used or not used at all will allow you to shop, safe in the knowledge that you will be able to fly with minimal disruption.
Third, make sure you can change the frequency after you have purchased the equipment. If you are careful to check before you buy if the system will allow you to do a manual glass replacement, if you have any problems you can later switch to a channel that is less busy. Some glass changes can be done yourself, while others have to go back to the factory to do the job. Regardless of your current situation, if you already have an RC radio setup, or are just thinking about getting one, putting a little footwork up front can go a long way to ensure you get the most enjoyment and flying hours out of your RC model.
