The problem has not showed up in my two motors while in the air. Only after on the ground and spinning it around at the end of the runnway. I do use the idle up/down programed on a switch. So maybe the extra 600 or 700 rpm is keeping it from dying while it is tumbling.

I dont think I would be giving up or writing off the DA50 just yet. These guys didnt get to where they are by just taking things in stride. I think they will get it worked out.
