Ahhhh OK
So they determine the open position of the wings??????/
So yah put them on so that you know what position they should be in??????
But if their not on you don"t care what position their in??????
Me I don't care so I'll keep em off
But obviously a lot of people do care what position they should be in
And if their not on sudden gusts of wind won't bother them???????
So I'm actually doing the wings a favor by not putting them on
