Control Of First Four Servos


I am trying to understand how does qgrouncontrol joystick values are sent to ardupilot. I can able to send commands to servos from 5 to 14 through “sendMavCommand” function. But i could not understand control of first 4 servos.

Which function send mav commands to 1 to 4 servos? Could you please explain how to transmit joystick values to ardupilot?

Any help would be highly appreciated.

That’s not correct.
You can use either MANUAL_CONTROL or RC_OVERRIDE messages. QGC uses MANUAL_CONTROL for joystick.
If you’re after ArduPilot support, moreso than QGC, it’s best to ask at
