Every operation that is controllable on an rc airplane is referred to as a ' channel '. The most basic plane will be just one channel which could be either motor control on/off (electric) or rudder movement. A 2 channel rc airplane will likely have motor and rudder control. To get a true feeling and understanding of radio control flying you should get a plane with three or four channels. A four channel plane will have throttle (motor power), elevator, aileron and rudder control whereas a 3 channel powered plane will have either rudder or aileron control but not both. More complex airplanes can have more channels, for example landing flaps and retractable undercarriage. There are no set rules as to how many channels an rc airplane must have, it all comes down to the number of functions the pilot wants to have control over. For the majority of 'sport' and club level rc pilots a 3, 4 or 5 channel airplane is the most popular.
