Estes Black Brant XII Upgrade Fin Set

The Estes Black Brant XII is a fantastic scale model of an iconic sounding rocket but unfortunately the kit has one major drawback. The first and second stage fins in the kit are a nightmare for the average builder to construct due to the way they are assembled and finished. Each fin in the kit is first glued together out of 5 separate die cut balsa pieces then carefully held in place with weights to dry, without the parts shifting position and hopefully without warping. Finally, each fin has to be carefully hand sanded in four different planes to create the correct airfoil shape and then filled and sealed before painting. WOW, that's 40 parts to perfectly glue together without misalignment or warping and 32 airfoil planes on 8 separate fins to sand so that they all match each other!
