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 swept shape fins are a clone of the Estes Maxi Alpha 3 fins, and in fact, these form the foundation of an upgraded Maxi Alpha-3. 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. Tired of your Maxi Alpha 3 fins breaking out of the plastic centering rings? Upgrade to these fins and to 29mm while you're at it! 3 fins per set.
