I have an X650 Value V4 and the APM2 but I'm having trouble calibrating the ESCs as they won't arm. I read on another forum that the X650 ESCs run from 200 - 1000µs rather than 1000-2000µs. When I check in APM the throttle goes from 1127 -1927, but when I check in the Parameter List it says THR_MAX 1000 and THR_MIN 0 so how do I lower the throttle from 1127-1927 to 175-1000?
I have DX8 with an AR8000 but there doesn't seem to be anywhere I can program this on the transmitter so I guess I have to do it in APM (?).
