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. Pro75® reloads are even priced lower than the competition, saving you more money.

Currently available in two through six grain sizes and nine propellant types! Try a Pro75® motor in your rocket - you won't be disappointed.
