RTL doesn't appear to work, runs away....

Hi All,

We've been having fun, my prior failure where the motors stopped, and the QC fell, I do believe is resolved by the video transmitter I was using.

So, now I've an onboard Hero2 cam which is working nicely.

Today was our first day using mission planner stuff, and everything seems to work until the RTL.

I believe it may be going to the launch point, but when it gets there (or maybe it just takes off before, not sure which), it takes off like a Bat out of hell, it's been going north.  

I've put it in stabilize and landed it, safely each time.

We've tried everything.

Here's the latest log file, the KMZ file, and a screenshot of my mission planner waypoints.

Thanks for your help and/or opinions, suggestions....

P.S.  Here's a YouTube of one time where I was barely able to fly it back, 'cuz it was so far away, it was hard to see.....  It was a different flying field than the "quadReport.zip" location.

    When you switch to RTL, and the aircraft head off north when it should not, each time I've looked into it this is what I find, that the aircraft was armed/launched before a good GPS fix was established, or after the GPS #of Sats count dropped below 4. Make sure you have a solid blue 3DFix light on your GPS before you arm/launch.

    I haven't looked at your log file yet, just sharing based on the basic symptoms, which are the same for 'copters and planes. 

  • I posted a similar instance.  I had a great flight with my new build but when I brought it in tonight to test since I hit 500ft altitude and I wanted to see how failsafe worked before I attempted anything higher.   I took the props off, fired up the quad, armed the quad, gave 50% throttle.. motors are humming along.    I shut off my radio.. motors go full throttle!.

    Maybe I should go outside with all props off  and test again. Or is dropping the LAND safer than RTL.
