The Estes Plugs for Large Engines are a must-have accessory for rocketeers flying with C11, D12, and E size engines, as well as larger 29 mm E and F engines. These plugs are designed to hold your starter in place during launch preparation, ensuring that ignition is consistent and reliable every time. Without them, pressure inside the motor may not build correctly—so keeping extras on hand is essential for smooth launches.
Engine-Specific Fit
Each pack includes 40 plugs in two sizes and colors for easy identification. The white plugs are made for D12 and 29 mm E and F engines, while the black plugs fit C11 and 24 mm E engines. This thoughtful design helps eliminate guesswork and ensures that your starter is properly secured to match the engine type you’re flying with.

With this 40-pack, you’ll always have spares ready, giving you peace of mind and the confidence to keep your fleet flying.
