High quality fin jig, however, the fin span could be wider.

Very limited use depending on the diameter of the fins

Pleasantly surprised with this plywood fin alignment guide. It was nice and thick which allowed for more precise fin alignment than some cardstock ones that I had previously used. I wanted my 2.6" LOC T-LOC to be perfect and this tool certainly did the trick. My T'-LOC put up a super straight flight! I highly recommend this fin alignment guide!
