Estes C5-3 Engines #10022 is an Estes model rocket engine for powered model-rocket flight and launch-day use.

That shorter delay window minimizes coast time and helps deploy parachutes earlier in the flight arc, leading to safer, more predictable landings; perfect for designs that don't benefit from long coasts or for flying in variable wind conditions. Each pack contains 3 C5-3 engines, 4 starters, and 4 starter plugs, giving you everything you need to prep for multiple launches. Just add your recovery wadding, launch pad, a
