One mod I didn't mention that i did was remove those lower landing mount pieces under the gears. Completely cut these flush. Apparently these were the landing pads of an earlier model? Lowered the weight and more importantly removed the vertical surfaces. Haven't had an issue with this and highly recommend for wind resistance.
BTW: How far and how high have you flown yours? Around 150 feet is about as far as I've flown mine and about 100 feet up. I live in an urban area so it's a little dicey sometimes.
