DO NOT use attitude (ATTI) mode in winter conditions unless you just want to tour the countryside for 25 min and never see your drone again... you need exceptional flying skill unless you are using it all the time. Use P (position) mode and the machine will stay where it is hands off unless the wind is over 20mph or so the S(sport) will be need just to keep it from being blown away....S mode just ups the max current so the motors can draw more power... but it also turn the anti-collision system off
