Details

The Estes C11-5 engine delivers a powerful punch for mid-weight rockets ready to soar. This single-stage engine features a 24 mm diameter and 10.00 N-sec of total impulse, making it a reliable choice for modelers looking for extra lift without moving up to E-class engines. Whether you're launching for altitude or demonstrating flight consistency, the C11-5 offers performance you can count on.

With a 5-second delay, the C11-5 strikes a great balance between boost and recovery deployment—ideal for rockets that require more coast time to maximize altitude before ejection. It delivers up to 22.10 newtons of max thrust, giving your rocket the force it needs to get off the pad with authority. The C11-5’s power and profile make it a perfect fit for rockets that are too heavy for a B or C6 but not quite ready for an E engine.

The engine’s 0.80-second thrust duration ensures a quick and responsive launch phase, helping stabilize your rocket as it climbs. With a max lift weight of 5.0 oz (142 g), the C11-5 works well with a wide range of mid-sized rocket kits in the Estes lineup and beyond. It’s a versatile choice for flyers who want to push their altitudes while keeping control and reliability at the forefront.

Each pack includes two engines, two starters, and four starter plugs—everything you need to power two thrilling flights. Whether you're a seasoned modeler or taking your next step up in engine class, the Estes C11-5 brings confidence and performance to your next launch.

The Estes C11-5 engine is a powerful single-stage engine built for mid-sized model rockets that need a strong boost off the pad. With a 24 mm diameter and 10.00 N-sec of total impulse, it delivers robust performance for flights requiring a medium delay between thrust and ejection.

With a 5-second delay and high thrust output, the C11-5 is a solid choice for rockets weighing up to 5 ounces. It provides consistent, dependable launches and is ideal for rockets that need a little more power than a B engine can offer.

Includes:
- 2 C11-5 Engines
- 2 Starters
- 4 Starter Plugs

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

John C.

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
