Problem:
My Hexcopter was flying manually to check flight stability after autotune.
Then suddenly the FC power was shut down and the copter crashed.
I looked at the fallen copter, and the FC power was on again.
I can not verify that the copter suddenly crashed and only the FC power was shut down and the ESC power was shut down.
Even if we look at the log data, we can not observe a drop in the altitude and a decrease in the motor output.
Now we’re done repairing the copter.
Since then, there has been no momentary power loss during flight.
I’m still anxious every time I fly because I can not find the cause.
One suspicious part is that the Power Module I used is 8S
The battery I used was 12S.
But the other copters we made use the same Power Module and use the 12S battery,
but so far there have been no problems.
Build:
Pixhawk Flight Controller running 3.5.7 firmware
Taranis X9D Plus radio with X8R receiver
Ublox NEO-M8N GPS/Compass
T-Motor U8 Lite 85kv motors with ALPHA 60A HV ESC
12S lipo, 22000mah battery (Tattu)
Configured using MissionPlanner version 1.3.52
The power module used the POWER BRICK MINI supplied with the PixHawk 2.1
Please refer to Dataflash log.
I can not figure out the cause.
