Hello

We have 7 drones. By mistake, I changed the PID parameter, and then I used auto-tune PID via QGC. I guess these steps changed the shipping conditions of the drone. But still the drones are fully not stable; how can I get back to the original condition of stability?

Drone Model: RB5
Hardware Version: M0052
VOXL-Suite Version: 1.1.2
PX4 Version: 1.14.0dev

Thanks,
Amin

@Amin-Bassiri You can either fully re-flash the drone or just run `voxl-configure-mpa` in order to bring the drone back to it's default state based on the SKU
