Pixhawk Shuts down when elevator or Aileron is used

Posted by Tim H on November 27, 2016 at 9:00pm

hello, 

 I have a quad I have been building, and have an issue. I had a problem with pixhawk where every time I would use Ele or Ail (props off) for more than about 3 seconds, the whole thing just beeps and shuts down.I then have to re-arm (throttle stick down, left, not needing to re-push the button). I tried using the arducopter 3.3 forum and cannot get an answer, so I came here. I have since replaced both the power module/cable, and the pixhawk itself. Running no external accessories, and i am getting the exact same issue again! I have spent hours and hours trying to troubleshoot this and scoured the internet trying to find an answer. I don't understand what I am doing wrong here, or why this is so difficult. I have build many drones using NAZA, CC3d, ect and never had the issues or trouble with setup as I am the pixhawk. Can anyone shed some light as to whats going on here?

    I do not know how to read them. Yes, I'm not well versed in Pix. This is first time using one. I have read and read till I'm blue in face trying to figure this out. And I thank you in advance for your help.

    What do the logs say?

  • Tim H November 28, 2016 at 3:04am
    Yes, this i understand and it does exactly that. In my case, I can have throttle to the wall, and just move the other stick over or up, down, and it wil shut down. I am using stock power hook-ups, (the cable with the chip, and wires that go to the pix.) And even using a BEC on the other rail (suppose to be a "backup") it will still do it. This is why I am about ready to just set it on fire!

    unless you throttle up it will auto shut down after about 3 seconds. This is normal and is by design.

    Make sure you are throttling up at least 20% or else it will disarm after a few seconds even if you are messing with pitch and roll
