Contrail Rockets is the premier provider of hybrid rocket motors to hobbyists, eduational institutions and scientific researchers.

Hybrid rocket motors use a solid fuel and a liquid oxidizer. Contrail motors use liquid nitrous oxide for oxidizer and have several fuel grain options.

The extra-ordinary flexibility and versatility of the Contrail system makes these rocket motors an outstanding value. The liquid oxidizer is loaded at the pad for added safety. Contrail motor components are not classified as hazardous materials, or even flammables. Contrail hybrid motors can be shipped without restriction anywhere in the United States and we also ship motors and reloads worldwide. Conrail Rockets reloads do not have to be stored in a magazine or under a permit or inspection.

Contrail rocket motors offer a wide range of thrust profiles because of our unique injector design. Injector fittings are supplied with the reload kits. The same motor casing can be used in numerous thrust profiles.  This is made possible using various injectors and graphite nozzle combinations, couple this with our various propellant formulas to provide even more performance opportunities.  Contrail Rockets is the only hybrid manufacturer with a Sparky Propellant.  Hybrid flyers are no longer limited to low thrust configurations.

If you can build it, we can lift it with a Contrail Rockets Hybrid Motor!
