Can't get motors to turn forwar or reverse

Hello Randy;
I loaded 3.2 rover firmware and id all calibrations.It arms and looking great.
I can’t get the motors to turn forward or reverse.I’m using a sabertooth controller and I’m connected to the pixhawk ch 1 and 2.It worked with 3.12 for forwrd and reverse.The difference is there is no skid out param to set.Very confused.
How do I set params for skid steer with the sabertooth in this beta version?
Thank You.

Hello,

We removed the skid_steer_out param in favor of new function on servo_out. On the ouput you want to use (1 and 3 previously) you need to set servoX_function : 73 for ThrottleLeft or 74 for ThrottleRight
