Yeah Bart, I'm there with you.
My MK red boards are far more reliable than the black ones. My Jib has crashed twice now due to the Black MK boards. The first crash, the pitch gyro failed and the Jib did a forward flip and crashed. It landed on it's feet but was enough force to collapse the retracts, bounce back up and land on the roll cage, which did it's job very well. It was nasty to watch but amazingly, didn't do much damage at all. That DW airframe is tough. Fortunately the AV200 wasn't on it at that time. We replaced the FC 2.1 ME with another, out of the box new, and flew it a little over an hour.
During that time, I never used Pos/Alt hold. Unfortunately, when I decided to try it, it was during a full up test with everything going....camera, video link, monitors, etc.. I was smart enough to fly over a friends yard which has 3 inchs of cushy grass. Just after takeoff, I climbed between 6 and 8 ft and flipped the Alt hold on. As it drifted slightly sideways, I flipped Pos Hold and the Jib suddenly climbed then lost power. During that time, the motors screeched as if they lost timing. It came down flat and the retracts again took the force and bent. The gimbal hit and collapsed the roll arms but the camera was fine and kept recording during the event. Again, the Jib is untouched.
I need to replace the retracts legs. I see that they are making extended legs for more cam clearance so that's perfect timing. Also, the AV200 has a crash kit, http://shop.quadrocopter.us/AV-200-Repair-Kit_p_503.html is now available....geesh, how many crashes did it take to decide on a crash kit?
I'm considering on using my old Okto red stack as it's up to date and has never failed me with a lot of FPV flying logged.
I may change to either the DJI system or the micropilot triple redundant systems, http://www.micropilot.com/news-2011-may-17.htm .
