I know to use a ubec to power the servo rail for servos used in an airplane, but what about gimbal servos? This is a pixhawk on a multi rotor with servos attached to three of the AUX outputs. Are the AUX outputs powered on the same rail as the regular outputs? Or should I power the servos separately directly to the ubec?
I ask the same question and RogelioN was kind enough to post this link

On the APM I recall there was a jumper to power that side with the bec. On the pixhawk it seems you would run a jumper from + on the input side to power that side with the bec. I think… it’s not %100 clear to me just yet either. But it looks that way after seeing the link.
