Hello:
I thought I’d try a Holybro Durandal FC and installed it on a +quadcopter. I flashed the latest Copter 4.0.x.
Running through the setup after a compass swing, I find the #3 motor won’t turn. That’s the front motor of a +quad.
I step back through all my settings and nothing is amiss. I load up BLHel_32 and can talk to that ESC fine and get the motor to turn. Swap all the cables back around and load up my quad param file and swap #3 servo cable with #4 at the FC and the failure follows it there. Then I setup AUX5(servo13) as #3 and all works.
It appears there might be an internal failure at MAIN #3.
Does anyone have another idea what might be causing this before I go the RMA route?
Thanks
