Had my first scary moment with my P3A the other day.
I tried to lod a Litchi mission but it refused, saying the GPS signal was too weak, so I just tried flying it around manually. It started swaying aroud violently and controls were unresponsive. Then it just sped off. I thought I was about to see the last of it, as it wouldn't stop when I ordered it to. Eventually I had to steer it back in my direction using the yaw control. Finally, I got it to land.
When I analysed the log with Healthy Drones, I found it had switched between ATTI and GPS over 30 times in a minute and a half, which apparently is a sign of a weak GPS signal.
I've done one Litchi mission since, and it was fine. But a mystery remains: why did it say the GPS signal was weak when it was picking up 16 satellites?
