Default RE: Really Basic Question - Channels

I thought my answer was clear enough for someone with radio experience. The other thing I would like to point out is that there is no such thing as a collective or pitch channel.

There is 1 channel for elevator and two channels for aileron servos (so 3 channels on the radio for the 3 cyclic servos), they work together with programming to control the blade pitch. A lot of companies call the second aileron channel the "pitch" channel but pitch is not a channel because it needs all three servos to change the blade pitch. In reality, with a computer radio it doesn't even matter which of the two channels you plug the two aileron servos into as you can change the direction the aileron works via the radio. For spektrum the channels are "ail" and "aux 1".

As a note, older non ccpm helis did have a pitch channel as 1 servo controlled the pitch by itself. This is not the case with 99% of the newer helis which use computer programming to have all 3 cyclic servos work together to control the pitch. The Trex 450X would be an example of a heli with an actual pitch channel.
