The Estes C5-3 engine offers retailers a versatile option for customers seeking a high-thrust motor with earlier recovery deployment. With 10.00 N-sec of total impulse and a 1.85-second thrust duration, this 18 mm engine is designed to deliver sustained power during boost, making it ideal for mid-weight rockets or builds with higher drag. The shorter 3-second delay ensures a quicker transition to recovery—an attractive feature for modelers seeking more control in variable flying conditions.

As an engine with a maximum lift weight of 8.0 oz, the C5-3 fills a specific niche between lighter A and B-class engines and the longer-delay C6-5. It supports hobbyists who want to experiment with custom rocket builds, payloads, or conditions that require early ejection timing. Its reliable ignition and consistent thrust profile make it a trusted choice for intermediate to advanced rocketeers.

Each retail-ready pack includes 3 C5-3 engines, 4 starters, and 4 starter plugs, offering end users multiple launches per purchase. Packs are clearly labeled and UPC-coded for streamlined inventory management and shelf display. As with all Estes engines, the C5-3 meets stringent quality and safety standards, which adds confidence for both sellers and end customers.

By stocking the C5-3, dealers can expand their engine assortment and provide a distinctive option that enhances the customer's launch flexibility. It's a smart addition for shops serving experienced flyers or anyone looking to offer a broader range of flight profiles in their engine selection.
