  • FAST & ACCURATE fin alignment
  • Great for three or four finned rockets
  • Fits body tubes ranging from BT-20 to BT-80

A precision molded accessory that makes it easy to glue three or four fins to various sized body tubes ranging from BT-20 to BT-80 diameters. Unique and adjustable vertical fin holders can accommodate either 3/32 in. or 1/8 in. balsa, bass or plywood fins. This is a must-have tool for any serious model rocket builder.

Never attach your fins wrong again and remove that painful process of holding them in place while the adhesive dries!

Not an "accurate" or "precision" tool.

I would not use "accurate or "precision" to describe this guide. It does not align the fins parallel with the body tube (or perpendicular to the base). I would not recommend purchasing it..

AMAZING

Simply amazing. Great for beginners. DO NOT USE ON PS II ROCKETS! It needs to be more precise. Also not the best for rockets that have 2 or more fin sets.

Fins do NOT align perpendicular to the body tube even

Fins do NOT align perpendicular to the body tube even paying attention to the 1/8 vs 3/32 markings. The spent casings (or blanks) are imprecise and are not fit to meet the specs of the tubes. Great novelty/concept, but poorly executed. (20+ year rocketeer. Going back to using my eyes and waiting on individual fins to dry.)
