Over here in lancaster ca it always seems to be windy its like 15 mph to 30+ mph gust mostly all day but I dont let it stop me I fly my 40 size extra 300s and spitfire in these conditions all the time, its funny when I get a rare day with no wind at all im not used to it. It feels weird and kind of boring lol nothing like getting blasted downwind by a 30+ mph downwind =D
