Hello,

I was testing with latest PX4 release **Firmware 1.6.0 RC**

My quad was doing the 3rd mission today (2nd set of fresh battery).  
=\> I used to fly successfully before.

I am using a **hobbyking pixhawk and 3DR power modules.**  
I also have a **redundant power supply by my ESC powering back my servos rail with 5V.**

During the last flight, it **stoped mid-air and crashed like after a hard fault**.  
I checked the log attached here [Flight Review](http://logs.px4.io/plot_app?log=9ea27c0a-5c42-4f30-920e-4f5095dbafe0)

And I can’t explain what went wrong.  
Estimation seams good

On the ground,

- The frame was in a bad shape
- The **motors were beeping** (like when they don’t have pwm signals I think)
- The **main LED on pixhawk was on, Green and Still** (not blinking like if it had restarted)

So I would guess that it should not be a power problem. otherwise it would have either no power on the ground OR the program would have restarted =\> the main LED would be blinking GREEN (and not remain still)  
Do you agree with me or I miss something, please ?

I didn’t find such a file on the SD card  
fault\_2017\_04\_03\_00\_26\_05.log

**In case I can reproduce this problem,**  
Would you have any suggestions, please, on what to do next time in order to try to clarify what was wrong ?

Thanks in advance for your help clarifying this problem !  
I wish you a nice weekend
