RE: Primos Real Wing and The Wing Thing ?
I have made my own using five primary feathers glued into a handle I cut out of some 1x pine. i have used it to immitate a fight very effectively. I also use it to make movement sounds while giving soft tree yelps. An early fly down and some soft calls have pulled a wary hened up gobbler to my shooter before all his girls had joined him on the ground. I think they are another tool worth the effort to carry.
