Tarot ZYX-GS problem

[Koippa]

Have anyone same problem than I have. When I put power on everything go well, but sometimes, every time outside, zyx-gs lost it's horizon, it runs to some direction. In flying it was going so far that i don't can manually correct horizon level. then when i pan, it was picture going like sin wave when panning 360. does air temperature effect something, i was get heli from house to out and flying. Out temperature is something about 0 degree celsius.

thanks

I try today morning at inside to put little piece of ice in plastic to get sensor to go cooler, and it was going to roll left. Then it was about 20degree roll left and i warm sensor, and it was begin to roll back to level. I think, with this system i must get it to outside so early that it can get to outside temperature before flight.
