Failed to drive servo with aux output1t

i tried to use aux1-4 outputs to drive four servos ，but not work，how to set up from the beginning.
the airframe is Generic Quadcopter x
the version of px4 software is 1.12.3dev.
use the QGC

I’d try it with v1.14 (beta or daily) and the actuators tab in QGC.

Are you trying to get a PWM output or a DC voltage to control your relay? I was only able to get a PWM output and then had to get a PWM to DC converter.

yes，u should add an UBEC in pixhawk to provide voltage for servo
