Sabertooth 2x12 Not Responding to Steering with CubeOrange

Hello everyone,

I am using a CubeOrange and a Sabertooth 2x12 motor controller. I’ve set the Sabertooth to “steering and throttle” mode, but it only responds to forward and reverse commands. There is no response to steering inputs.

My DIP switches are in the following configuration:
1: DOWN
2: UP
3: UP
4: UP
5: DOWN
6: DOWN

On MP my servo parameters are set : SERVO_1_FUNCTION = 26, SERVO_3_FUNCTION = 70.
And my RC is mapped : RCMAP_PITCH = 2 , RCMAP_ROLL= 4 , RCMAP_THROTTLE= 3, RCMAP_YAW= 1.

Has anyone else experienced this issue or have any suggestions on how to fix it?

Thank you in advance for your help!
