For those of you who would like to find out more about what is involved in loading and flying these motors, download a quick start guide by clicking on the button below:
Since 2011 I have been researching, manufacturing and flying these fascinating little motors. Over the years I have assembled three volumes comprised of notes to myself, instructions for my motor customers, useful tips for owners of any manufacturer's cartridge-based hybrid and some of my research results pertinent to flying rockets with these motors. Previously I offered these publications for sale in a series of three PDF manuals (over 300 pages). I am now making these manuals available free of charge for anyone who has an interest. Hopefully they will help you decide if you would like to try and enter the small cartridge-based hybrid motor arena.
Dexter Labs Micro and Mini-hybrid User's Manual - 187 pages - current version 2/9/24
This PDF covers the background development, motor types and features, assembly instructions, static testing, motor specifications, performance of various fuels, previous lessons learned, success and failure description and quantification, references and extensive resources. This is followed by over a dozen detailed how-to appendices.
Dexter Labs Micro and Mini-hybrid Rocket Construction Manual - 191 pages - current version 2/4/24
This PDF covers construction of airframes suitable for use with micro and mini-hybrid rocket motors. It is broken into three major sections; 1) details of specific airframe components, 2) examples of over a dozen commercial kits modifications and scratch-builds to fly with these motors, and 3) detailed instructions for two prototype kits I have designed specifically for these motors.
Dexter Labs Test Stand Paper - 40 pages - current version - 1/4/24
This PDF covers the construction of an electronic static test stand useful for micro and mini-hybrid rocket motors and also useful for commercial and experimental solid fueled motors as well. This test stand is capable of monitoring and recording both thrust and chamber pressure.
For the time being I am making these manuals available by direct e-mail request. To obtain these manuals please e-mail me at:
