Hi all!
Just had my first fly-away today which was scary. From reading other posts I assume I had magnetic interference when taking off.
I hand launched the MM from the aft/rear of a small boat with a 200hp outboard motor. I have launched the MM from the same boat the day before, but from the stem/front without any problems.
What happened was that the MM lanuched ok, but as soon as I gained altitude and made some distance from the outboard motor, it suddenly darted away forward att full speed. There was nothing I could do to stop it. I tried to turn e t c, but the MM just sailed away at full pace and I realized that I quickly had to do something drastic. So I pulled both sticks downwards until it crashed in a field of thorn bushes. We were boating in a canal at the moment, so luckily there was land to crash the MM in/on.
I think that the outboard motor generated a magnetic interference which affected the "magYaw" input. As soon as the MM was away from the outboard motor, it freaked out and became virtually uncontrollable.
It seems to be unharmed though. I think I only need to change the props. What bothers me a little bit is that the drone never recovered in flight. If, according to the GPS, the drone travels at speed without any input from the RC - why does it not stop flying away??? In my opinion there must be an overlooked bit of code there.
Lesson learned? Never launch the MM from near the outboard motor or other electronics (which many of you already know and so do I now by learning the hard way).
