Shuglu,

I watched you video. That hurt. To me it looked like cg was ok, you had control until you started the bank and it just kept banking and rolling, nose dropped and she went in. Looks like total radio failure, either from fault in system or failsafe that locked up the controls and didn't reset in time to recover. If it was a servo failure or even a control surface coming off, you would have still had some control. It looked like once that last bank was started, you had none. Really sorry to see that.

However, I've been flying mine, it flys great and I have almost a hundred flights on it now. Go for another Zero. They just fly great. I use Fataba radios an have had no problems on 2.4. I've read reports that spektrum systems go to failsafe and take too long to reset, but personally don't know.
