Brother found this yesterday at a yard sale for $5.00 dollars and gave to me. Came with 6 different packs of 4 inch feathers and a new pack of fletching tape unopened. Being the S-1000, it's for straight fletching. I thought all vanes had to have a twist for proper flight? I have been watching youtube videos. seems pretty simple to use to me. Straight fletching? Heck, maybe I just haven't paid much attention.
