The AeroTech Disposable Motor System DMS is a single-use motor in kit form that is assembled by the user. All of the Aerotech DMS motors use all-disposable components. The nozzle and propellant are already installed. You will need to set the desired delay time using the Universal Delay Drilling Tool (UDDT), Not Included, and then pour in the ejection charge. The Universal Delay Drilling Tool (UDDT) is required to adjust to a shorter time delay on all DMS rocket motors and is available in the AeroTech Accessories section of this website.

DMS motors feature a filament-wound fiberglass casing, a glass-reinforced composite phenolic nozzle, a molded plastic bulkhead and RCSs exclusive White Lightning™ aerospace grade composite propellant formulation, which produces a brilliant white flame with lots of dense white smoke and a throaty roar at lift-off.

This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Initiator. Requires HAZMAT shipping via UPS or FEDEX. The sale of this high power motor to persons under 18 years of age is currently prohibited by federal law. This is a High-Power motor requiring Level 1 High-Power certification through NAR or Tripoli to purchase.

Aurora T. ★★★★★

Assembly took me about ten minutes and the fit was snug but straightforward, which surprised me for a disposable. The all-disposable nozzle and propellant design means zero cleanup after the flight, and it burned exactly as expected. Really solid value for a single-use kit.

Lily F. ★★★★★

I was really impressed with how cleanly the nozzle and propellant fit together during assembly, and the motor burned exactly as expected for a single-use kit.

Charlotte M. ★★★★★

Setup was a breeze, even for a first-timer, and I love that everything is disposable so there's no cleanup afterwards. The motor fit perfectly in my 38mm rocket and gave a clean, solid burn that pushed it to a satisfying altitude on a calm day.
