There are only 5 places to plug things. So, how are you going to get 6 channels? Do you plan to start soldering things to the circuit board?

The receiver provides Channels 1-4 + 6. That's it! There is no dedicated battery port. You either feed it from the ESC, or you put the battery on a Y with a servo.
