Hi,
I did 2 flights today and on the second flight suddenly all motors stopped and I had a total crash…
Can someone help me with reading the log file?

Looks like a power failure, but the voltage in the log looks unusual.
Starts off at 17v, goes up to 19v when you increase throttle and goes up to 20v when you increase throttle further.
It looks like you asked for 100% just before the power failed?
Hi, no I did not ask for 100%, at least not myself cause I was in AltHold mode when suddenly the motors stopped…
I had to build everything new and I just changed the power module. We will see what happens…
thx for your first analysys
