Quick answer

For most builds, use a Fin-Lok™ mount with the AeroTech Arcas/Wart Hog style precision airfoil molded fin for secure alignment, or glue it directly to the body tube if you prefer a permanent mount.

Fin-Lok vs. direct glue: which is better?

Fin-Lok™ mounts let you swap fins or align them precisely without measuring, while direct gluing is simpler and lighter but permanent. Your choice depends on whether you value adjustability or simplicity.

What about the fin material?

The fin is made from high impact polystyrene, which is durable and holds shape well. It's the same style used on AeroTech Arcas and Wart Hog kits, so you know it's proven in the field.

Frequently asked questions

Can I use this fin with a Fin-Lok™ mount?

Yes, the fin is compatible with 1.9 or 2.6 inch style Fin-Lok™ mounts. Slide the fin into the mount and secure it according to the mount's instructions. Check your Fin-Lok™ size before ordering to ensure compatibility.

How do I glue the fin directly to the body tube?

Apply a thin layer of plastic-compatible adhesive to the fin's root edge, press it against the body tube, and hold it in place with tape until the glue cures. Use a fin alignment guide for best results. Use a fin alignment guide to keep the fin straight while the glue dries.

Is this fin a single fin or a set?

The product includes one fin only. If your rocket needs multiple fins, you'll need to purchase the appropriate number. Count the fins your rocket requires before ordering.
