4 Channel RC Helicopter
Is 4 Channel RC Helicopter the Right Choice for You?
All set for RC helicopter shopping? It is important for you to know the number of channels you will need. Each channel for the helicopter controls a surface or an important part. This indicates that the more complex RC you have, the more channels you should go for.
4 Channel RC Helicopter Radios
4 channel RC helicopter are an ideal choice for micro coaxial RC helis that have cyclic controls. These radios also go well with helicopters comprising of rotor helis of hobby grade that are fixed pitch single types combined tail rotors. If you are using a toy grade coaxial 4 channel helicopter, the first channel controls main rotors speed. The second channel is needed for acquiring control over yaw movement (left and right) via changing counter rotating rotors speed. The third channel plays a vital role in controlling the forward and backward movement of the pitch. Now the last or the fourth channel is exploited for controlling both the left and right movement of roll.
If you are using RC heli with single rotor fixed pitch, then the first channel will work for controlling the speed of main rotor. The second channel controls pitch of the tail rotor or the speed to ensure smooth turning of the device towards left or right direction. The third channel is used for forward/backward cyclic movement whereas the fourth channel will take care of left/right cyclic movement. 4 CH RC Heli are ready to fly helicopters.
