Tilt Servo Not Moving in Y3 Drone

I assembled a VTOL drone with a Y3 configuration. The flight controller I used is the Matek F765 WING, and the firmware I flashed is ARDUPLANE 4.5.7. During the tuning process, I found that when switching between the MANUAL, QLOITER, or QSTABLIZED modes, the tilt servo didn’t move. I’ve already set the tilt servo to other channels to ensure that the tilt servo is working properly. I think it should be a logic problem of the flight controller. Moreover, I noticed that when I set the servo output of the flight controller to “servo1 function=75/76”, the output was grayed out on Mission Planner. I’ve been looking for a solution for a long time but haven’t solved this problem yet. I hope someone who knows can provide some help. I’m uploading my parameters, and please take a look.

Update mission planner. Some times those fields will grey out if you’ve made changes but you need to re-boot/re-connect the controller to reset.

However, I directly modified the parameters. Now the problem is that the tilt servo doesn’t move when switching between the fixed - wing mode and the vertical take - off and landing mode.

Try setting the trim to 1500

Do the servos move at all? Are they stuck in the positions shown in the image?

It’s not a problem with the servo. I set servo1 out and servo2 to other channels, and the servo works normally.I just don’t know where the problem lies.
