Hello. I have an pixhawk px4 board on my quadrocopter. This model will not have any rc control because
it will be controlled via mavlink from orange pi. How can i set up my flight controller without rc?
Be sure that you do setup a conventional RC link for testing and tuning.
You cant configure and tune a multirotor without an RC link, then you will still need it during testing in case you need to take control.
Only once all bugs are ironed out would you remove the RC link and use only GCS.
