This should be a FAQ or sticky somewhere (unless it is and I missed it!) But someone pls tell me what each channel is used for on a heli. I used to fly 4 ch RC aircraft and I know throttle, ailerons, elevator, and rudder but obviously helis are different and add a few! As I think about my 1st heli options, I'm still scratching my head on 2ch, 3ch....7ch. If I missed it somewhere, a link to a description would be fine too.

Thanks!

Jeff
