I am pretty new at this, and don't have any experience with Pixhawk. I have been trying to set up my servos with my Pixhawk, but am not getting any response from the servos. I am flying a flying wing and trying to set it up so that I can switch from Auto to Manual. I am also attaching a servo/gimbal to the drone, so I don't think that I can configure it through the servo/gimbal configurations on mission planner. From what I have read, when I switch to Manual mode, the Pixhawk should automatically pass transmitter signals through, so I don't need to change that. I have my BEC plugged in, and have armed it to check, but haven't gotten anywhere. What do I need to do to get my servos to work?
