Well I gotta buck the system a bit because I fly -when it is a bit too windy for my other stuff 15 to 20 mph wind . I fly a hundred mile per hour STRYKER because it is light fast and cheap it will really rock with the wind and I just cruise on the upwind leg . This is also good conditions for any type of flying wing with way too much power . Actually in wind that isn't just rediculous all u need is two times the power to weight ratio.. just my tried and tested opinion
