If the environment is windy a spinning broad head would be the least of your concern. The wind will effect the whole arrow regardless.
The idea behind wind planing is, your broad head is directed by the air as it cruises though the air at a high speed. It can create lift or steer your arrow off course. Where the broad head is directed the arrow will follow. Much like a fixed wing on an airplane. Although with a wing on a plane one can control the lift with adjustable 'flaps' (I think that's the word I'm looking for, not sure). Although once the arrow leaves the string you are not able to control is flight. The theory with the spinning insert is that the broad head is now free from resistance and and will not resist the air as it travels at a high rate of speed. If it can't resist the wind it wont guide the arrow off course. I'm still a little skeptical but from my initial test it sure changed my mind!
