just wondering if putting a right helical on quikspins 3.125" vanes is correct? or does it have to be left or straight? thanks.

Right helical, right offset, or straight will work just fine.

Nap does not suggest a helical. They suggest a slight offset, go to WWW.newarchery.com and go to FAQ's they should give the exact specs.

thanks. the site said straight or 1 to 3 degree offset. i guess i'm getting another jig for my bitzenburger. i am assuming that 1 to 3 degrees is very slight? does anyone have a pic of it? thanks again.

On one my set ups I actually found that with a right helical my fixed blades grouped alot better with the quick spins. The small deggree offset like recommended wasn't enough. But that was my setup, and type heads using.
