Help with RC calibration!

:exclamation: :question:

[size=150]I have no clue what channels on my receiver box to use for channels 7 & 8 on the ArduPilot inputs.
Do those channels even matter when calibrating the RC?[/size] :question:

[size=150]I’m using the Spektrum AR8000 Receiver[/size]

[size=150]I’m also using this transmitter[/size]

Your help is appreciated, thank you very much.

On my Spektrum DX7 I use the 2-way Gear switch (R/C receiver channel 5) for APM channel 7 and the 3-way Flap switch (R/C receiver channel 6, Aux 1) for APM channel 8.
