Compact Bulk Pack - 9 Engines for A8-3, B4-4, B6-4 Mini

The combo pack includes a total of 9 engines - three A8-3 engines, three B4-4 engines, and three B6-4 engines. Starters and plugs are also included. Before purchasing, please ensure that these engines are compatible with your specific model rocket.

These engines are perfect for low and medium altitude model rocket flights. The A8-3 is a single-stage engine designed for rockets weighing less than 3 ounces, including the engine. It's an ideal choice for first flights and small flying fields, as it allows you to get accustomed to your rocket's performance and landing within the flying field.

The B4-4 engine is suitable for rockets weighing roughly between 1 and 2 ounces, which is typical of most rockets measuring 1 to 2 feet in height. This engine will nearly double the altitude achieved compared to the A8-3.

The B6-4 is a medium impulse engine that provides high-altitude flights. It works exceptionally well for launching larger, heavier rockets as well.

Please note that it is crucial to verify the compatibility of these engines with your specific model rocket before making a purchase.
