The CPPro has a separate normal 6-channel EFlite rx and a"3-in-1" mixer/gyro/dual esc unit. It is easier to set that heli up with a different receiver, but it has the same issue with the transmitter, if you want to use a different transmitter with the stock rx the arming/reversing/ccpm mix problem comes up again but in a different form. I think it is easier to solve though, I know of some folks who are using Futabas and JRs with the BCPP but I do not know the specifics.
I just put a DX6/AR6000 in mine, no more problems.
