What blade grips are you using? Im using 4-4 blade gripes and Im also flying even in mild windy conditions (5-10 mph winds) The stronger the wind the more a challenge it is. Also adding weight to the heli will help a lot when flying in windy conditions. I also fly with a custom body installed which adds some weight which helps me out a bit and also Ive redesigned my crutch in which I fly with an extended mainshaft which gives me a higher rotor head which results in a more stable flying machine. You can see the design on website Http://darthdrk.4t.com on the modification page.
