Micro-hybrid rocket motor (D power class) - complete hardware $99
Mini-hybrid rocket motor (E power class) - complete hardware $125
Mini-max bi-hybrid (D boost to E sustainer) prototype motor beta (level 2 certification required to participate in beta tests) $120
Lightweight casing (33% lighter for the micro, 28% lighter for the mini) add $12
A note on lightweight casings…micro and mini-hybrid motors are heavy for their power class because of a number of reasons not the least of which is the steel nitrous cartridge. In an attempt to obtain the best flight performance out of these motors I offer this lightweight case option. The tradeoff is robustness as these lightweight cased motors operate near temperature and pressure design limits; therefore all things must go right, and the tolerance for error is minimal. If you are just starting out with these motors I suggest purchasing an extra standard weight casing when you order a lightweight motor. Perform all your tests (static and flight) with the standard weight case and then fly your performance flights with the lightweight case!
Each motor is precision "hand"-machined from aluminum, brass, stainless steel and graphite. The motor is supplied with a copy of an extensive user's manual (also available as a stand-alone product) including background and history, assembly and launch instructions, performance data, resource lists and more.
