Enerjet E30-4T Model Rocket Motors

The Enerjet by AeroTech E30-4T composite propellant model rocket motors provide over twice the power of the D12 and 1.3 times the power of the Estes E9 model rocket engine! That's not all, you also get a bright violet-blue flame with a minimum of exhaust smoke on each flight! These powerhouse engines fit all flying model rockets built for the Estes D12 and E9. The E30-4T is the correct delay time to be used in place of a D12-3, E9-4, E12-4 or an E16-4.

AeroTech composite propellant rocket motors are the most powerful and technically advanced model rocket motors in the world. AeroTech motors use the same type of propellant found in the Shuttle and military rockets. Pound for pound, this propellant can deliver over 3 times the power of black powder used in other model rocket engines. AeroTech composite model rocket motors allow you to fly larger rockets, heavier payloads, and achieve higher altitudes than ever before!
