Apart from the spelling, what is the difference between Jetex and Jet-X?
Jet-X, made by Powermax, is a similar concept (a reloadable metal motor system) but came about much later. Production began in the mid 1990s. Results have been variable in terms of certain vintages of fuel and overall weight of their 1997 Z series motors remains a concern. But refinements of old products and developments of new ones was formally announced in late 2006 as the company reorganizes under new management.
