Pixhawk Disarming

Posted by Erik on December 29, 2014 at 3:36pm

I'm running into an issue with my Pixhawk that hopefully one of you can help me out with.

Problem:

So I just finished my first build, but before my first test flight, I wanted to ensure everything was as ready as possible while on the bench.  I turn on my transmitter, connect my battery, and hit the failsafe switch on the copter.  After the copter appears ready, I arm it by moving my throttle stick to the bottom left position and I get a solid blue LED on the Pixhawk (no GPS yet).  At this point, I am able to spool up the motors - everything seems great.  At some random point within the next 30 seconds however, my Pixhawk disarms itself.  I cannot seem to figure out why.  I am able to re-arm from the transmitter, but hate to take this thing out for a maiden flight until I get this figured out.  Why is this happening?  Help?!

Build Specs:

Pixhawk Flight Controller

SunnySky 4108S 380Kv Motors (x6)

Tarot 680Pro Carbon Frame

DX6i Transmitter

6S 6000mAh Turnigy Battery

Thanks in advance,

Erik

    Under the "Arming the Motors" section, read the 2nd Note:....midway down the page.  

    The Wiki is an excellent read....lots and lots of helpful information in it.

      This was really helpful, thank you!  I was able to fire up the hexacopter when I got home from work today and with the motors running, I never disarmed.

      Now I have a new problem, I can't takeoff!! :)

    I don't think you have a problem.  I have noticed on a couple of occasions that if I don't raise the throttle and takeoff within 15 or 20 seconds that my quad disarms. 

    I have never really tried to find a repeatable time.  It may be a safety feature since there really isn't much reason to sit at idle for long with the props spinning.

    I would just hover it a couple of feet over some soft grass or other forgiving surface to see if it isn't just fine the way it is.

      Will do, thank you for the feedback!  I just spent so much time and money on this build that it's making me paranoid to finally fly it. :)

      Will test it out soon and update.

      Regards,

      Erik
