Default flat spin problems, what is causing this death spin.

I find much comfort in the fact that you can recognise when you're doing this. I thought that perhaps it was a subconcious compulsion at this pint, er, point......

Thud, I'm tending to believe you and certainly more than one has gone down with the pilot blaming the radio rather than the real cause. But it IS a possibility that can't be overlooked given the backgound of the set. And even a quick up glitch would cause DR to respond exactly as you described and suddenly we have the same situation regardless of whether it was a pilot induced control or a radom glitch that started it. There, happy Bill?

Either way the model is still the cause of it's own downfall. In that you're 100% right. If it didn't have the stall/spin problem then a glitch wouldn't fire it off line like this. And there ARE all the other times that DR was able to recover after it got into a bad situation.

If indeed it was a bit dutch roll'y then moving the CG back to where it should have been may have made it just that little bit more stable. The straw on the camel's back and all that.

DR, what was the snap/ spin reactions of the other model like? It was stable in normal flight you said but I'm thinking about what it was like when you purposely snap rolled it. Did it recover immediatley or did it like to keep turning for a 1/4 or 1/2 roll before it came back to normal? Or did it tend to keep spinning by itself after you started one and it needed to be flown out of the spin or took a turn or two to come out by itself?
