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 Metalstorm™ aerospace grade composite propellant formulation. Metalstorm™ is a sparky propellant, lights easily and produces a large brilliant white exhaust plume, a long yellow-orange dense spark trail, and plentiful white sparks that fan out in flight. As with all rocket motors using spark-generating propellants, special precautions must be taken to avoid fires around the launch pad by clearing the immediate area of all combustible materials in accordance with applicable fire and safety codes.
