Estes C5-3 "Super C" Standard 18mm Rocket Booster Engines (3-Pack)
The Estes Super C is back! Reintroducing the Estes C5-3 engine – 50% increase in maximum thrust over a standard C engine and the punch you need to propel those heavier rockets off the pad. The Super C is a great choice for larger birds and for payload rockets, like competition egg-lofters, that need that extra push.
Estes Standard 18mm Engine 3-Pack. Standard Estes engines fit the standard BT-20 body tube and are 2.75" (7.0cm) long and 0.69" (18mm) in diameter.
3 pack includes engines, instructions, igniters, and igniter plugs.
