Overview: The Different RC Radio Frequency System

When the RC frequency spectrum was first introduced to offer controlled facilities for radio control (RC) modelers, it was limited to a set of just 6.

These frequencies were not labeled with channel numbers as they're these days, but had been represented by multi-colored flags; purple/white for 72.320 MHz (megahertz), red/white for 72.240 MHz, and so on. Having only 6 frequencies to choose from was fairly restrictive and meant a lot of RC airplane pilots had to be grounded, waiting to take their turn on a given frequency.

The RC model airplane frequency spectrum these days is significantly broader, consisting of a significantly larger batch of 50 channels in the 72 MHz band within the USA, a equivalent batch inside the 35Mhz band within the UK and other bands according to country.

Additionally, there remain a couple of 27 MHz channels shared across numerous uses such as for 'park flyer' model airplanes, and a handful of other more specialized channels reserved for licensed amateur radio operators.

For convenience, I'm just going to refer towards the 72Mhz band as the band allocated for model airplane use inside the USA. You may require to read that as the band allocated for model airplane use inside your own country.

So now you have decided to purchase your RC model and radio equipment you also need to decide which radio frequency you are going to operate on. As opposed to most other attributes of the sport, picking a well-liked channel which is used by a lot of other people just isn't an excellent concept.

Choosing a standard 72 MHz frequency for your radio could be as simple as going towards the local hobby store and
purchasing one with a standard radio setup. But randomly choosing a channel can result in a problem in the event you do not do a little investigation initial.

Firstly, determine regardless of whether you're going to be a park flyer utilizing 27 MHz or going for a much more advanced setup on 72 MHz. The 27 MHz channels are mainly devoted to what are regarded as "park flyers".

These pre-packaged systems generally come with everything you need to get up and flying and are intended for the casual flyer that just desires to get out, get in the air, and not mess with the higher expense of a more complicated airplane and radio setup.

Picking a RC model airplane park flyer package having a pre-set frequency requirements small to no investigation because you have small option as the packages provide you with a choice of only 3 or 4 channels, some FM, some AM. Channel conflicts in a RC park flying scenario are much less typical due to the big number of parks and flying locations accessible to the casual pilot.

But in the event you do invest in a park flyer then be aware that there might properly be other pilots on the market in the park utilizing the same frequency as you - and that will mean expensive trouble once you shed control of one's airplane, or even worse if some stranger accuses you of causing his airplane to crash.

Second, if you're going for 72 MHz then go to your flying field and learn what other individuals are utilizing. Envision arriving to your preferred RC model airplane flying field only to locate a person else already utilizing the channel you've got just paid out excellent funds for. Some clubs have rules pertaining to what takes place in this circumstance.

As only one pilot can operate at a time on a given frequency this typically implies pilots having to switch off and take turns making use of the frequency - and some means of the club controlling the changeover procedure either by physically taking control of the transmitter or just having a process written into the club rules.

If you are flying at a busy site that's not a sanctioned flying club with rules and bylaws, you might locate your self sitting out and unable to fly for the day.

The smartest way to pick an RC frequency for your radio would be to do some legwork first. Visit the field exactly where you'll do the majority of your flying. Investigate what channels are already in use and which channels are seldom employed.

Finding one that's infrequently utilized or not used at all will allow you to purchase, secure within the nowledge that you simply will probably be in a position to fly with minimum interruption.

Third, make sure you can change the frequency following you have bought the equipment. If you take care to check just before you acquire whether or not the program will enable you to complete a manual crystal replacement then if you run into a problem you can alter later to a channel that is much less busy.

Some crystal adjustments you can do your self while other people have to go back to the factory to have the function completed. Regardless of your present situation, should you already have an RC radio setup, or just thinking about acquiring one, doing just a little footwork up front can go a long way.
