I recently finished rebuilding my 650mm Quad with U5 motors, still trying to fine tune it. I decided to play with filming blasts at work. Something is off.
The first clip is from a DJI phan2, my Black quad drifts in from the left in loiter mode. Without changing anything myself, it looks like it tries to land (loose altitude) I don't know exactly why.
I need help figuring out this happend so I can prevent it from happening again. I have attached the log file if anyone is willing it help.
the Status shows Err: Baro-2, Err: Baro:0. but the errors seem to happen after the loss in alt. At the time of alt loss, the THRin seems to drop from hover to 0 then kicks up again when I switch to Stabilize. Could the close prox to the Cell tower be to blame, or does it look more like something else? I'm still learning how to decipher logs accurately.
side note, I was having issues with my 3dr GPS showing any Sat's while having the FPV & 3dr's minimOSD powered on, I added a second 3dr GPS and I usually have 10 or more Sats. Has anyone else had issues with the minimOSD and GPS lock?

I think the short answer is that your throttle stick moved to 20% causing it to descend. You had some drift in loiter (GPS can do that and if it's slow, it won't trigger as a glitch) You can see the altitude drop as soon as thrIN drops to ~20%
I don't see any messages in the log for the second GPS either (Though I need to verify how that message is saved in a dataflash log)
Did you Ever figure this out I had the same thing happen today switching to guided mode baro error I didn't save it though ouch!!
