Pro38® reloadable high power rocket motors were introduced at LDRS20 in June 2000.

Fliers quickly found out what sets them apart from the rest - super-fast and hassle-free assembly, adjustable delays, instant ignition, and mess-free unloading.

With the quickest and most reliable factory-supplied ignition system on the market, Pro38® motors are the smart choice for clusters and upper stages.

Available in six sizes from G to J, and three propellant types, there's a Pro38® motor ideal for your application.

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!

With the Pro75® and Pro98® line of reloadable rocket motors, CTI pioneered cross-brand compatible reloads that fit and are industry-certified in both ProX and RMS hardware. Each reload is supplied with o-rings that allow the reload to be used in either brand of hardware, giving you more reload choices and saving you big bucks in the process. Of course, we designed features into our hardware that we feel make it superior, like ACME-threaded retaining rings with an accessory wrench to make reloading easy on your hands, and gland-style o-ring seals for reliability. Pro98® reloads are even priced lower than the competition, saving you more money.

Pro98® motors are available in 1,2,3,4, and 6 grain sizes, from L to N class. Currently available with Classic propellant, but like we keep saying, there's more stuff in the works!

New for 2005 are the incredible Pro98® Classic propellant moonburners. These motors feature a one-piece grain with an offset core for amazingly long burn times (the M520 burns for 14.25 seconds!) and are already setting altitude records in their class. But with high initial thrust they can lift large rockets too, for slow realistic flights that seem to go forever. Best of all, we offer these for the same price as our standard core-burners!

The Pro150® O5100 is the largest industry certified high power rocket motor on the market today.

Due to the high cost of the motor hardware, and the limited number of hardware sets liable to be available for loan or rent through normal channels, Cesaroni Technology Incorporated offers a hardware rental program through its dealers. When placing an order for a Pro150® reload kit through your dealer, the dealer may order from us a set of rental hardware to be delivered with the reload kit. The rental hardware will be packaged with the reload. The hardware must be thouroughly cleaned and shipped back to CTI freight prepaid as soon as possible. Additional details will be available from your CTI motor dealer.
