Estes D12-3 Model Rocket Engine (2)

The Estes D12-3 is a high-power, single-stage model rocket engine designed for larger, heavier rockets that need strong thrust and a moderate delay before recovery deployment. With a 3-second delay, the D12-3 delivers impressive altitude performance while allowing the rocket to coast briefly before ejection.

• Total Impulse: 16.8 N-sec (Class D Engine)
• Thrust Duration: 1.6 seconds
• Delay Time: 3.0 seconds
• Maximum Lift Weight: Approximately 226 grams (8.0 oz)
• Optimal for: Larger, heavier rockets requiring strong thrust and moderate coast time before ejection
• Recovery Delay: Moderate delay allows rocket to coast toward peak altitude before deploying recovery system

Each D12-3 engine pack includes:

• 2 D12-3 engines
• 3 igniters
• 3 igniter plugs
• Recovery wadding

Recommended Use: For use in rockets designed for D-class engines, especially heavier builds that benefit from strong initial thrust. Ensure safe launch practices by following the NAR Safety Code and local regulations.
