I have a Pixfalcon setup as shown in the build thread.
I have completed the setup and everything works on the bench as expected in both multi rotor and fixed wing- except, the left motor does not run in any case. (Testing in ACRO flight mode)
Problem is an apparent lack of signal on MAIN 2 servo pin connector.
Left motor will run if I move the signal to MAIN 1 or MAIN 3.
Continuity is confirmed from back of connector on PCB to the signal pin on the servo header and the solder joints look clean.
I've looked through parameters but I'm not seeing anything that would resemble disabling port MAIN 2.
