Uncontrollable Quad Rotation, loss of control and crash,

Posted by Barry Nash on June 4, 2012 at 11:56am

 

 

In the end, all that broke was my mount for my GoPro.

I am thinking that it had something to do with my declination setting.

I should not have flown when i noticed the oscollation at take off, then I should have landed it. I had a weigh point programmed and had 3D lock on my gps.

All input would be appreciated.

Thanks in advance.

    Hi Barry, did you have any luck solving this issue?  I'm having a similar problem with my Hexa at the moment and I'm not sure what the cause is yet...

    What is the best order of pids to tune. I think ive got my rate P set ok now.

    Something sounds out of balance to me.  Odd higher frequency oscillation.  I assume this is a quad?

    APM1?

    Definitely need to drain a couple of batteries just hovering it relatively close to you.  Need to get that yaw issue sorted out first.

    Then try ALT HOLD, then LOITER, then RTL, then AUTO

    Each one will pose its own challenges.

    Just my .02

    You didn't have any YAW authority it looked like. That was very scary. Wow. Did you try flying in a stabilized or acro mode to see how if you have that same problem?
