Pixhawk cube using s.bus


I am currently using a futaba 7008sb and a 18mz controller with a pixhawk cube on arduplane 3.9.1. I have been trying to get these to work using the s.bus through the RCIN. I have been unsuccessful. I have checked my set up on a legacy pixhawk and it worked. But i have yet to make it work on the cube. Any suggestions?

Hi, I have recently started using SBUS.
Make sure you servoX_trim are correctly set to the actual max and mins. For some reason the radio calibration did not pick this up.
