I made a hexacopter frame and hired CUAV V5+ flight controller with fetched and builded PX4 1.12.3 firmware.
I had got wind tunnel test with the drone. After the test flight, I found that the firmware parameter and configuration have been reset to default.
The situation was only happened once and never repeated yet but, as you know that this would be very critical. Is there any reported cause and solution for the issue?
Thanks a lot.
