Ok, I’ve used Mission Planner to calibrate my engines/ESC’s. They calibrate fine. I move the throttle, they increase and decrease in speed like they are supposed to. Then when I disconnect The Mission Planner and the battery and reconnect the battery, later on, it seems to go through the motions of checking battery size, etc but gives me no control over the motors. I ran the calibrate cycle a couple of more times with the same results. All switches and throttle in the correct position.
Is there a reason you are using an older firmware?
Perhaps an upgrade would help?
