Explore the Estes F15-4 Engines (29 mm) at MegaHobby. This model rocket engine pack is selected by its complete engine designation, not simply by the letter class.

Product features and specifications

The Estes F15-4 engine delivers high-thrust power and long burn times, making it a reliable choice for mid-power rockets. With a 4-second delay, it’s optimized for heavier, single-stage rockets needing a smooth boost-to-deploy transition.

Built for performance, the F15-4’s extended 3.45-second thrust duration provides impressive altitude gains, while the 29 mm casing ensures compatibility with a wide range of larger rockets. It’s an ideal choice for modelers ready to step up from D and E engines.

Includes:

2 × F15-4 Engines

2 × Starters

4 × Starter Plugs
