## Features

- Combo pack includes 9 engines total — three A8-3, three B4-4, and three B6-4 engines. Starters and plugs are included. NOTE: Please verify that these engines are compatible with your model rocket before purchasing.
- All the engines you need for low and medium altitude model rocket flights!
- The A8-3 is a single stage engine designed for flights in rockets weighing less than 3 ounces, including the engine. It is ideal for first flights and small flying fields as you get used to how your rocket will perform and where it will land in your flying field.
- The B4-4 engine is suitable for use in rockets weighing roughly between 1 and 2 ounces, which is typical of most rockets being 1 to 2 feet tall. It will almost double your altitude compared to the A8-3.
- The B6-4 is a medium impulse engine that delivers high altitude flights. It works great for launching larger, heavier rockets, too
