yeah isnt CP gonna require another channel? I would like to be able to advance to CP some day when I learn what the heck it is, I have an idea but not sure....but wouldnt look forward to having to get a 5 or 6 channel radio to fly it...or worse yet a computer radio.....too dumb to read manuals.. I just want to fly,, 4 channels can sneak up on ya awful fast when your 2 feet off the ground.......Rog
