Each moving part will need a servo to make that part move. Radio systems are available with a wide variety of features. However, they all share similar quality and basic functions. When you first look at a radio system, you'll see how many channels it has and then what channel it's on. When deciding on a radio, it is important to decide on how many channel functions you want.
Most airplanes use four channels.
So, you may want to think about the future and what plane you want next, and buy a radio that will control all anticipated functions. No license is needed to operate these radios. Many fields have a frequency control system. Before you use your radio, be sure you understand the system and are using it correctly. A radio wave of any frequency can have different signal types.
