I’m building a quadplane using the Pixhawk lite. I’ve got the plane motor working. However, I can’t seem to get the quadplane ESCs to arm. I’ve using Gforce SimonK ESCs. I swapped out one of the ESCs for a non-simonK ESC to see if it would fire up. No luck. In the latest try, I’ve disabled any arming requirements. I’ve spent hours and hours of this with no luck. GPS and compasses are working. Tried to arm using MP. Got Mavlink rejected command. Any ideas? Thanks.
