  1. Selecting a R/C Radio Matt Winit Fern Prairie Modelers AMA #1921 FPMCTraining@comcast.net

  2. Why so many channels? • The number of channels on a R/C radio coincide with the number of things on the plane you will be able to control. • Radios on the market today range in channel count from 1 to 14.

  3. So how many channels do I need? • The majority of trainer airplanes require a 4 channel radio. • The 4 basic control surfaces on most trainer airplanes are: • Ailerons • Elevator • Throttle • Rudder

  4. The hobby store said something about a 3 channel radio… • By eliminating the ailerons, you could operate on 3 channels. • In this configuration, you would need to use rudder to turn. • Most people are happier in the long run with 4 channel aircraft, because they are more capable. • The cost savings between 3 and 4 channel radios is quite small.

  5. What about a radio with 6 or more channels? • These radios can be quite a bit more expensive. • You have the option of using any number of channels on the radio, so a radio of this caliber could also be used for training. • If you are planning to upgrade to larger airplanes in the future and have the means to buy a bigger radio, it might be a wise investment.

  6. Computerized or standard? • Now that you have decided on the number of channels, you must decide whether you want a computer radio or standard radio.

  7. Computerized or standard? • Computer radios usually have a small screen where users can program all sorts of different settings. Some of these are: • Multiple aircraft memory • End point adjustments for control arms • Elevons and flaperons • Dual rates for control surfaces

  8. Computerized or standard? • Standard radios usually allow you to make just the basic adjustments, such as: • Trims • Direction of control movement

  9. Computerized or standard? • Once again, this decision becomes one tailored to the individual. If you plan to move on to larger, more complicated airplanes, the investment in a computer radio may save you money down the road.

  10. Frequency selection • The next decision is whether you would like to operate on the 72 MHz or 2.4 GHz frequency? • There are 50 frequencies dedicated for model aircraft use by the FCC on the 72 MHz band, and only one frequency can be used at a time. • There is no limit on the number of 2.4 GHz radios that can be used at once, as they each have their own unique link.

  11. Making the right choice… • It is possible to buy virtually any combination of channels in either a computer or standard type setup. • Consult with your instructor and people at the flying site before making a decision. There are a lot of opinions out there!

  12. Manufacturers • In addition to types, there are a number companies who produce radios…
