Model Rocket Motors & Engines

Model rocket motors and model rocket engines are the power source that safely launches and recovers your rocket. Our range of rocketry motors includes trusted rocket engines UK customers rely on for schools, beginners and hobby use. Designed for consistent thrust and reliable deployment, these motors are suitable for educational projects, classroom demonstrations and hobby rocket kits.

Important

Rocket motors are classed as dangerous goods in the UK. This means that they can only be purchased by an adult who is over 18 years old. Motors must also be shipped in accordance with ADR regulations.

More About Rocket Motors

How rocket motor classification works

Model rocket motors are classified by letters (A to O) and numbers. The letter indicates the total impulse range, and the number represents the average thrust in newtons. For example, a C6-3 motor has a total impulse range of 5.01 to 10 N·s, produces 6 N of average thrust, and has a delay of 3 seconds before firing the ejection charge.

Motor sizes and power levels

  • Low Power Motors (A to E): Suitable for beginners and small rockets.
  • Mid Power Motors (F to G): Require some experience and can lift larger rockets.
  • High Power Motors (H and above): Used for larger, more advanced rockets and 
    require certification.

Motor Codes

  • A motor code like C6-3 breaks down as follows:
  • C: Total impulse range.
  • 6: Average thrust in newtons.
  • 3: Delay in seconds before the ejection charge.

Storage and handling

  • Store motors in a cool, dry place away from heat sources and direct sunlight.
  • Handle motors with care, avoiding rough handling or dropping.

Safety and certification

  • High power motors (H and above) require certification from organizations like the 
    National Association of Rocketry (NAR) or Tripoli Rocketry Association (TRA).
  • Always use safety glasses and follow launch safety guidelines.

Choosing the Right Model Rocket Motor

Selecting the correct model rocket motor is essential for safe and successful launches. Motors vary in thrust, burn time and delay, which determines how high the rocket flies and when the recovery system deploys. Smaller and lighter rockets typically require lower-thrust motors, while larger rocket models need more powerful model rocket engines to achieve stable flight and safe recovery. Using the correct motor improves performance, reliability and overall safety.

Model Rocket Motors for Beginners

For beginners, starting with the right rocketry motors makes rocket building easier and more enjoyable. Entry-level motors provide controlled thrust and predictable recovery, making them ideal for first launches and school use. Beginners should always match the motor size and power to the rocket kit instructions to ensure safe operation and consistent results.

Safe and Reliable Rocket Engines UK

All of our model rocket motors meet recognised safety standards and are suitable for supervised use in schools and educational environments. These rocket engines UK customers trust are designed for consistent ignition, stable thrust and reliable recovery system deployment. Proper storage, handling and adult supervision are always recommended when using rocket engines.

How Model Rocket Engines Work

Model rocket engines operate in three stages. First, the motor produces thrust to lift the rocket from the launch pad. Next, a timed delay allows the rocket to reach peak altitude. Finally, an ejection charge deploys a parachute or streamer to ensure safe recovery. Understanding how model rocket engines work helps beginners choose the correct motor and launch rockets safely.
