Pixhawk Crashlog 3.2 rc5: Anybody can help?

Hello everybody,

at first, english is not my native language, but i hope to explane so good as possible.

My hexacopter crashed a few days ago in the trees, after the failsafe jumped into RTL-Mode, because i forgot to set the failsafe off for lost connection to my tablet pc.

Ok, today i was flying outside on the field again and would try to test the RTL-Mode one more time, but my hexa crashed down from more than 28m like a stone after i switched on the RTL-Mode.

After my full crash and four pieces broken frame and a lot of damage in my head i analyzed the last logfile.

I cant find some issues,... nothing.... no RTL-Mode logged, no stopped motors,... really nothing.

Is anybody here, to analyze this logfile again?

It´s not possible to find nothing!

I changed RTL-Mode and all motors stopped at same time.

Thank you very much, to do your best and hope to find something strange.

I used arducopter version 3.2 rc5.

  • I see nothing unusual, except for sudden power loss /end of log at ~30M AGL

    You should check the power supply to your Pixhawk, and add some redundancy.

    • I was wondering, because all ESCs was beeping after the crash.
      Are you shure?
      What do you mean with "redundancy?
      I checked all wires at first and cant see any difference before the flight :(
      • ESC's have their own power supply. - they often beep on PWM loss.

        PWM goes away when pixhawk loses power. - so they beep.  (Pixhawks PWM microcontroller shuts down too)

        Redundancy; Pixhawk is able to take up to three different power sources, and switch intelligently between them, both at too low/high voltage, with priority.

        • Thanks, i understand it.

          My Pixhawk was connected with 5v from the 3DR Currentsensor and second with an external 5v BEC.

          And i cant understand why it should lost the power, when i swiched to RTL Mode....?

          Do you mean it was purely coincidence?

          • if you have a working redundant power supply, (if you can disconnect the 6p DF13  the primary (powermodule) , and pixhawk continues to run)

            THEN this is a clear sign of possible software crash, you are running beta - 3.2

            • Later i will check this out.

              At first i clean my motors and solder the ESCs on the new frame 

    • ???

      • oops, my bad -(posted some ansers to wrong threads.)

        - in your case log ends suddenly at ~19200  -  most likely a los of power to pixhawk, check it's power (+5v) and add some redundancy.

  • I uploaded to my dropbox.... Here it is:
