NAZA M hard landing

I was flying my hexacopter this weekend and had been adjusting gains. I've noticed that on descent I get kind of a corkscrewing motion so I'd been playing around with the vertical gain.

I'd just lowered it by 10 and flew away from me about 50 feet. I was doing a slight climb and yaw at the same time and suddenly the hexacopter started cork screwing badly. It started coming straight down as if in a fast descent. I throttled up to full power trying to slow it but there was no response. I landed hard and broke 2 arms and one landing gear.

I have an IOSD Mark II and looked at the logs.

Not sure I totally understand how to read them. There was a lot of wild roll, pitch, yaw change at the point of crash. The motors all seem to be wildly powering up and down

Anyone seen anything like this?

I'm not sure that's it. It was flying perfect. I can yaw perfectly without any TBE. I never have any TBE when flying. This was a loss of input control and the aircraft was not acting like it was rotating around a point off the center of the aircraft.

It was like it was spinning around it's center (not TBE) but pitching in a cyclic fashion. It would be like taking the aleron and elevator stick and rapidly moving it in a circle. When
