That would be the best choice. 6 Channel (DX6i) is minimum. All my receivers are AR6110e (or similar) and none of my planes or helis use more than 6 channels. I still have an DX7, and one day, I might spend more $$$ and get a 7 channel receiver. I could control lights or camera with another channel. If you spare the extra $$, the DX8 is the newer transmitter, and I understand the menu may be easier to use.
