AeroTech H550ST-14A 38mm x 203mm Single Use DMS 1-Motor Kit - 085514

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 Super Thunder aerospace grade composite propellant formulation, which produces a bright violet-blue flame with a minimum of exhaust smoke. Super Thunder motors provide a higher ISP than Blue Thunder.

This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire Initiator.

Requires HAZMAT shipping.
