## Description

You will get one package of each Estes A8-3, B4-4, B6-4 mini bulk pack - includes a total of 9 engines

Review: Watch the Rockets Soar! - Engines do what they're required to - shuttle your hand-made creation into the sky! (And maybe into trees, powerlines, stranger's back yards....) And they're excellent in doing so. Starting with the A8-3, you can get a sense of the fun of rocketry without having to have long distance running stamina. Engines go in the bottom of the rocket, typically by clipping in to the engine holder (if you built it properly). Once the igniter is shoved in and secure, the countdown builds excitement. Always count down. Check for stray fools walking into the launch area. etc. These are designed to just-fit, and they do. They're a one use item, so be ready to buy lots of these, if you don't lose your rocket during a B6-4 flight... Very fun! Use on low wind days for the next enjoyment factor. Use on windy days if you want to get some cardio in. Perfect for kids, and tinkerers. They also can be used on other things, like toy cars, your sister's favorite doll (duct tape works), or whatever else. But remember, they're rocket engines, and are as dangerous as they are fun. Adult supervision recommended. (Losing a rocket on its solo flight can crush a child's excitement)
Review: Engines - As advertised.

## 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
