Aerotech High-Power J425R-14A 38mm Disposable Motor System (DMS).

The J425R-14A DMS Single-Use and other DMS motors are different from previous and existing reloadable and single-use motors in the following important ways:

• No hardware to buy, load, clean or lose
• High strength, light weight filament-wound fiberglass casing
• Lighter weight casing means higher performance
• User adjustable time delays in 2 second increments
• User adjustable ejection charge. No more "one size fits all" charges
• High reliability due to less potential for user error while retaining superior customer adjustability
• Low cost

DMS motors feature a glass-reinforced composite phenolic nozzle, a new molded plastic bulkhead and ship with a FirstFire igniter and bondable thrust ring.
