Hello,

I am currently working on a project with 3 quadrotors using PX4 on Pixhawks. When I do the setup on QGroundControl, I am currently flashing the firmware with default settings, and then modifying the parameters (gains, filter parameters, ect…) for each drone manually. I am wondering if there is an easy way load the same non-default settings to each device?

Thanks!
