Description

Save yourself the trouble of cutting your own plywood fins with thee sturdy through-the-wall (TTW) 1/8 inch thick laser cut plywood fins. The trapezoidal shape fins resist breakage on landing better than any other type of fin, since they are tucked up above the nozzle end of the landing rocket, so the spent motor nozzle bears the brunt of the landing force. Strong plywood construction and TTW design ensures that you spend more of  your flight time flying, and less time repairing broken fins. TTW fin design relies on fin tabs that anchor directly to the airframe tube and also the motor tube through slits at the aft end of the airframe tube, ensuring superior strength and straight alignment, because the fins are glued to both the airframe tube and the motor tube. 3 fins per set.

One of the coolest features of these fins is the option to engrave your own logo on the fins!  Just click the Choose Files button in the Logo Upload section, and you can upload your logo!  It will be engraved on one side of each fin!  In addition to your logo, it's a good idea to include contact information--an email address or phone number--to help your rocket find its way back to you if you don't recover it. Customization may add up to 48 hours to your order ship date.
