Micro Rocket Motor and Model Jet Resources


Why we're here exists to serve the world-wide community of enthusiasts for models powered by micro rocket motors, especially those exemplified by the Jetex series of engines.

Our mission is to be the premier Web resource for information and advice about such models and the motors that power them.

Who's behind it is the collaborative effort of enthusiasts from around the world. Contributors come from Australia, Canada, England, France, Germany, Japan, South Africa, New Zealand, the United States, and Wales. Their names can be found in the 'Acknowledgments' section at the foot of every content page.

How we got here

The domain was founded in 1999 by Dr L Edward Jones (below left), a retired chemist, engineer and life-long Jetex enthusiast. Under his direction, the site quickly established itself as a definitive source of Jetex history and technical information.
