AeroTech Releases Three 38mm DMS™ Motors at LDRS-32

Length: 14.03”
Propellant: White Lightning™



The I140W, I280DM and J270W motors are TRA certified and can be purchased by flyers possessing an appropriate NAR or TRA user certification. They are competitively priced at $39.99 for the I140W, $54.99 for the I280DM and $59.99 for the J270W.

The time delay of DMS motors may be shortened using AeroTech’s Universal Delay Drilling Tool™, which is being provided free of charge to each customer who purchases one or more DMS motors (one free tool to a customer, please).

Motor performance data including a sample time-thrust curve are printed on the motor label.

DMS motors are packaged in a distinctive yellow shipping tube with AeroTech logos printed on the outer spiral wrapping, and the same motor label applied to the outside of the tube for easy identification and performance evaluation by the flyer. Caps on the ends of the tube are applied externally and are easy to remove.

The 38mm DMS motors feature a glass-reinforced composite phenolic nozzle, a molded plastic bulkhead and ship with a FirstFire™ igniter and an integral thrust ring. The thrust ring is designed to fit standard motor retainers.

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
• User adjustable time delays in 2-second increments
• User adjustable ejection charge
• High reliability due to less potential for user error while retaining superior customer adjustability
• Low cost

Additional DMS motors are under development including a series in 54mm diameter. DMS motors are perfect for Level 1 & 2 certifications and for general sport flying.

The DMS motor design and the Universal Delay Drilling Tool are patent pending.

AeroTech`s DMS line ushers in a new era of ease of use, low cost and spectacular performance to the modern hobby rocketry market.

"DMS- When you just want to fly!™"
