It was odd, when I armed the Pixhawk initially, all four props were opersating, throttle up, all props spinning up to full throttle. I didnt make any further changes. I then went into ESC calibraiton mode, and only two spin. How about that!
So I understand the order from the diagram. The bit that I just need to further clarify. On the ESC it says something like:
Then next to the cables that leave the ESC for the motors is says M1, M2, M3, M4. So are S1 and M1 linked? And S2 and M2 and so on? I think you are saying they are from your reply, but could you please just confirm.
So then from that I can figure out (by using the diagram) which colour leave, needs to go in which channel input on the Pixhawk.
