The HP-I140W-14A is a single-use High Power motor, from the Aerotech DMS(tm) family of motors. Its thrust is positioned on a middle value and makes it good for a large variety of rockets weighing in at 2-2,5 Kg. 

DMS (Disposable Motor System) motors are already assembled and ready-to-use, you don't need to reload anything. This is a great advantage when you need ease of use and a fast turnaround, just like Estes motors: you install the motor in the rocket, launch it and throw it away after use. No need to buy reloadable casings.

The only operation required is the delay adjustment. The included delay is 14 seconds long and you can adjust it with the UDDT - Universal Delay Drilling Tool.

This reload requires the purchaser to hold a Level 1 HPR certification.
To purchase this reload you have to send us your certification papers or your membership card showing your certification level.
