Pro54® reloadable high power rocket motors were introduced in 2002, and with all the great features of the Pro38® line set a new standard for 54mm reloadables. With the Pro54's, CTI introduced the industry-first vernier adjustable delay tool. With no pre-set stops and a range of 10 seconds, you can fine-tune the delay time to best suit your rocket. Again, Pro54® motors feature the quickest and most reliable factory-supplied ignition system on the market, making them the best choice not only for single motor flights but for clusters and upper stages too.

Please check out Andy Woerner's 350 pound 1/7 scale Vostok with a cluster of 20 Pro54® motors - he knew which brand of motor to trust in this monster project!

Currently available in two propellant types, Classic and Smoky Sam, and six sizes from mid-J to L class, there's a Pro54® motor just right for your application. More Pro54® products are in the works!
