sorry for the noob question but I've searched everywhere and couldn't find answers to the following:
The RC channels assignment 1 to 4 is common and understandable
Channel 5 for flight mode selection is also understandable, but my question is why only 6? I can relate with some radios not having two 3 way switches that would allow more selections. Was that the reason?
Channel 6 why the limited selection of commands (I'm using APM planner 2.07) mostly related with fine tuning and calibration. Why limit the selection of actions available? Also why only two positions?
Channel 7 and 8. Why only two positions each? Was it the same reasoning of the choice of channel 5?
I forgot to mention that I'm using the latest APM 3.1.2 with a PixHawk. My RC Radio is a Spektrum DX9 and the receiver is a OrangeRX R800X and is connected via the SBus out to the PixHawk RC IN, so theoretically I could use more channels, but can't find a way to enable channel 9 on the APM.
