A6-4 Model Rocket Engines – Six Pack

A6-4 model rocket engines are designed for lightweight rockets, longer coast phases and gentle, stable flights. These low-thrust model rocket motors provide a smooth lift-off followed by a longer delay before the ejection charge deploys the recovery system. This makes the A6-4 engine ideal for slim rockets and designs that benefit from a slower ascent and extended coast time.

This six-pack of model rocket engines is well suited for schools, beginners and educational rocketry projects where predictable performance is essential. A6-4 engines are commonly used in classroom demonstrations and supervised launches, helping new rocketeers understand thrust, delay timing and safe rocket recovery.

The rocket motor dimensions are 18mm x 70mm

Each package includes:

• 6 A6-4 Engines
• 6 electronic igniters
