The Advantages Plywood Centering Ring Baffles with Lasercut Balsa Fins for Optimal Model Rocket Stability

Model rocket enthusiasts know the importance of engineered motor mounts and fins for optimal stability. Plywood motor mount rings can drastically improve model rocket stability and performance. In particular, these engineered rings offer improved rigidity, more consistent lift-off patterns, and no chance of breaking or bending like some kit manufacturers produce. Our lasercut fins permit a more efficient transfer of the CP (Center of Pressure) to the back end of the model rocket body for a much more stable flight. This increased stability allows for higher accuracy in flight control and offers better protection against unforeseen wind gusts too. All in all, with the right set of engineered baffle rings with lasercut fins in place, anyone setting up their model rockets are sure to have greater success and satisfaction when they launch their models into the sky!


What is a Mylar Foil Parachute and How Does it Enable High Visibility & Safe Rocket Landings?

Mylar foil is a lightweight, reflective material that is often used to ensure high visibility and safe rocket landings. The material has been used for decades to help guide rockets safely back to Earth.
