Not currently shipping. For historical reference only.
TRA doesn't even recognize/honor Kosdon motor certifications issued
from NAR and on the NAR/TRA joint certified motor list, much less the
TRA motor certifications our product line received. GFL seeing them certified.
This TRA policy is contrary to their rules, to NFPA-1125, and the law.
AeroTech announced a price increase for 29mm SU 110 G to $24.95 each
in 1-05. Competition is bad? TRA banned Vulcan, Kosdon, ACS, USR, and others.

Propellant Styles and Outputs (reads) One of the unique aspects of U.S. Rockets motors is a wide variety of options of propellant outputs all with very similar ballistic properties. Therefore we have more shippable motor propellant styles than any other vendor. This page shows a variety of motors in operation, in various sizes so you can see what to expect. |
|
24mm Expendable (Single Use) Generally for model rockets under one pound for power levels C-H as model rockets. Perfect starter or crossover motors moving up from model rocketry (MR) to large model rocketry (LMR). |
|
29mm Expendable (Single Use) The overall most popular motor size in the (over C power) world! Use in model rockets under one pound with power levels C-G and in large model rockets under 3.3 pounds with power levels E-H. 29mm also can cross over into HPR a bit with H-J. Perfect for repeat sport flyers and for use in kits from MR to LMR to HPR. Amazing diversity of motor choices make USR stand apart as your primary motor supplier. |
|
38mm Expendable (Single Use) For High Power Rocketry (HPR) power levels H-K. Get started in larger HPR rockets and stay with the standard motor size we pioneered (38mm) and which has become a true industry standard. When you see our offered motor choices you will soon see why! |

24mm Reloadable The only "grease-free" and "reload o-ring free" reloadable motor experience in rocketry today is also the only system which has 7 fewer leaks than the "other" systems and allows you to reload in almost as little time as prepping an expendable. This diameter is tube compatible with other 24mm product including Estes and Quest. Use caution with thrust on wimpy rockets. Use our rockets for higher thrust motors. U.S. Rockets knows rockets! |

29mm Reloadable The only "grease-free" and "reload o-ring free" reloadable motor experience in rocketry today is also the only system which has 7 fewer leaks than the "other" systems and allows you to reload in almost as little time as prepping an expendable. Last we checked the flying experience was about flying, not fiddling with lots of little parts at the launch site during hot or cold weather as you sweat to death or your fingers freeze off. Our reload kits are "glove compatible" and "big finger compatible". U.S. Rockets knows rockets! Innovative propellant styles too. |
|
38mm Reloadable The only "grease-free" and "reload o-ring free" reloadable motor experience in rocketry today is also the only system which has 7 fewer leaks than the "other" systems. We love saying that! This is the standard motor size we pioneered (38mm) and which has become a true industry standard. There are some companies proffering 62.5g propellant based reload systems as "easy access". Bogus. Our 125g systems are technically superior and are within the only meaningful weight limit. The 125g model rocket weight limit proposed by U.S. Rockets and adopted by NAR and translated to many laws and regulations since. The 62.5g limit is merely a DOT-E-7887 and CPSC limit and has no meaning to adult supervised launches or anything except a narrow range of DOT class shipments. 38mm systems can fly on maximum model rocket power (minimum) and can range in power through H, I, J. Custom variants deliver K and L power. This is a versatile size. |

Custom Motors U.S. Rockets has long served military markets. We now serve the new MIL-COTS market, commercial research and testing, movie special effects (rent "Top Gun", "The Running Man", "Mosquito Coast", "Flight of the Intruder"...) and even the custom amateur market for financially secure humans who launch in remote desert launch sites worldwide!! Big toys for big boys or space rated thrusters for activating your spy satellite, we do it all. And yes, we toot our own horn. Being THE leader gives us that right with humility. Beep, beep. And when pushing that launch button on your own flight remember, "the harder you push the higher it goes." (grin). |

IGNITERS AND ACCESSORIES U.S. Rockets offers several igniters (purchased separately with reloads, included with expendables) and accessories to provide basics such as spare igniters, as well as specialty items such as special staging igniters, clustering igniters, dual deployment system expendables, and much more. |
