Hi,
I am using this copter quiet a long time. Now it just fell down stopping all rotors mid flight.
Could someone check my log file if there is something to discover and solve?
I think about a battery issue but I am not able to read the logs right.
Thank you for any help on this

Your CURR.Vcc drops precipitously at the end of your flight. In fact, it
falls off a cliff to below 4.7V. Your PixHawk is not going to like that
at all. That sort of drop would certainly explain PixHawk stopping.
Also. Turn on arming checks.

Hi peterbarker,
thx for your answer.
Does this come from the lipo? What shall I do? I don’t want to see that happen again after repair…
thx

Assuming you only have one battery on board - yes, it comes from the LiPO, probably via a BEC or power brick.
The simplest way to avoid this is to enable (and configfure correctly!) the battery failsafe. I can see that it is currently misconfigured - you are flying on 6S and the FS_BATT_VOLT is 10.5 - suitable for a 3S setup.
Hi peterbarker,
thx. I will check that. I was flying with 4s…
thx a lot
