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 Blue Thunder™ aerospace grade composite propellant formulation, which produces a gorgeous bright violet-blue flame with a minimum of exhaust smoke. Blue Thunder™ motors provide a higher level of thrust than White Lightning™ motors of the same total impulse and are perfect for high lift-off acceleration.
This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Jr. 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. Orders containing this item will not be shipped until proof of age (such as a copy of a driver’s license) is received.
Certified by the Tripoli Rocketry Association (TRA), the National Association of Rocketry (NAR) and the Canadian Association of Rocketry (CAR).
