hey everyone . i have had a cx and a cp rtf and now im assembling a mx 400. im trying to set up the radio . i have a futaba 7uap pcm and a futaba 6 channel reciever. i have the manual for the tx but it is very vague (or should i say very technical ) but i cant figure out which channel to use for the collective pitch servo. this is my plane controller and is geared towards that but there is a heli preset as well.in the manual it looks like its using the 2>6 mix toggle for the idle up mode . any help out there?
