Welcome to Micro Nitro Rocketry, maker of small cartridge-based hybrid rocket motors. These motors are based on a design by Rene Caldera from the mid-1990s. I am “hand” machining these motors in very small batches (typically 4 motors per run to minimize tooling change-out time and material waste). In addition I am offering prototype rocket kits specifically for these motors along with some related products: Specialty products include: Publications. Precision machined motors. Replacement parts and consumables like O-rings and burst disks. Support equipment. Specialized rocket kits. Micro-hybrid and mini-hybrid rocket motors use whipped cream dispenser chargers and almost any combustible material (like shopping bag paper or PVC plumbing pipe) for propellants. These small experimental motors are easy to operate and inexpensive to fly using rocket kits from us, modified Estes and Quest kits, and scratch-builds of your own design. They are direct descendants of the "Micro Hybrid" rocket motor designed by Rene Caldera and sold in kit form two decades ago (see the Video Extras page). They are arguably the most elegant hobby rocket motors of their size ever designed! |
