Umm, well where i was looking(helihobby), I costomize the T-rex. Its has the Hitec Eclipse 7 transmitter only with Spectra Modules as a choice of radio. Then I need a reciever. There are 3 choices: Hitec Futaba Shift 6 Channel Dual Shift Receiver, Hitec JR Shift 6 Channel Dual Shift Receiver, and Futaba Receiver R146iP PCM 72MHz. None of those are qpcm. Does this mean either i get a reciever, but never use it, or dont get the radio at all?
