When you order an item that has a frequency channel choice (such as radio systems, receivers, modules, crystals, etc.) the last 2 digits of the stock number will be asterisks. For example, the stock number of a Futaba 4YF 4-Channel radio is FUTJ40**. To order a radio on a particular frequency channel, check the chart below. Once you've clicked the BUY NOW button a screen will appear that will allow you to choose frequency. Simply pull down the SELECT A FREQUENCY menu to select one.
To select the best channel number (frequency), first consider what you are using your radio for. Some channels are reserved for aircraft use and some are only for surface model (Boat/Car) use. Choose your channel number accordingly. Check your local area and talk to the people you fly or race with - some channels in certain areas are subject to interference because of other radio broadcasters on nearby channels.
Important: Please Read
Tower Hobbies supports the
Academy of Model Aeronautics (AMA) 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 usually 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 nitro 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.
There Are Four Different Channel Groups To Choose From
- Aircraft Use Only (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 megahertz, Channels 61-90): Cars, boats, and other non-flying models must use one of these channels. Radios designed for cars/boats exclusively with a steering wheel or pistol grip control are only available on these channels.
- All Uses (27 megahertz, Channel Code A1-A6): Although legal for all models, we suggest that you use 27 megahertz only for surface models. This is because of the possibility that some unseen operator may innocently be operating a surface model on the same channel within range of your model airplane which would cause interference and a possible crash.
- 2.4GHz Spread Spectrum Technology One of the most exciting new breakthroughs in hobby radio technology is the use of 2.4GHz spread spectrum technology -- which gives modelers of ALL skill levels the fastest, smoothest, most accurate and most reliable control possible. Futaba's 2.4GHz radio equipment in particular has advantages that greatly benefit new R/Cers. Simply by pushing a button, you link the receiver to a single transmitter -- each 2.4GHz transmitter has been assigned a unique ID code at the factory. Once that link is set, the receiver responds only to that one transmitter. In addition, Futaba 2.4GHz systems never stay on a single frequency for more than two milliseconds. You never have to worry about signal conflicts, and never need to wait for an open frequency when you're eager to enjoy a day of racing or flying with other modelers!
Note: that countries outside the United States may offer different frequency allocation schemes
