The reciever in the CX2's 4-in-1 is an AR6100 with slightly altered servo pins (A few connect to the mixer board). If you want to use the DX7 there was a thread listing all of the variables that needed to be entered. Other than that, a CX2's 4-in-1 would be all you need!

Does anyone have any pointers on how to the setup the CX with DX7. I would imagine you would need the AR6100 receiver instead of the AR7000. Also, would the receiver from the CX2 work with the DX7 or is it complete different?
