All NSWRA members are entitled to fly rockets with motors up to a total impulse of 20Ns (equivalent to black powder "D" motors), and black powder "E" motors. (Low Power Rocketry)

Members need to have Medium Power Rocketry (MPR) Accreditation to fly rockets using composite motors in the range "E" to "G" (impulse greater than 20Ns, up to 160Ns).
PLEASE NOTE: There are now a number of new "G" motors available such as the Aerotech G138T that fall outside the total propellant weight or total impulse range and will require HPR accreditation to fly.

To use motors "H" and above ie. High Power Rocketry (HPR), individuals need to be certified by the Tripoli Rocketry Association or AMRS(separate to NSWRA) See the HPR certification page for more information.

A member applying for MPR Accreditation must be a NSWRA member in good standing. The member should be able to provide evidence of experience in low power rocketry and demonstrate that they are capable of successfully making, launching and recovering small model rockets. Evidence could include rocketry log books or flight record sheets. The member should know the meaning of any terms used in this procedure.

Procedure for Applicant

  1. Provide evidence of experience in low power rocketry to a committee member
  2. Determine the weight of your completed rocket. If the rocket is scratch-built, the CP location must be known and/or marked on the rocket
  3. Determine a motor appropriate for the rocket, and which is suitable for the launch site restrictions. Ensure that the weight of the rocket ready for launch is not greater than the maximum weight recommended for the rocket motor
  4. On the launch day, complete section 1 of the Application form. Give the form to an approving member
  5. Present your rocket for inspection by the RSO. The RSO will assess the rocket and its construction, including ensuring that its stability is greater than 1 calibre (CP must be known if the rocket is scratch-built). The RSO will check that the total weight of the rocket is less than the maximum weight recommended for the motor, and that the rocket will not exceed the permitted altitude. The RSO has the final decision if a rocket can be launched
  6. Assemble the motor (if a reload) under the supervision of the approving member
  7. Launch and recover your rocket
  8. Present the rocket to the approving member
  9. The approving member completes section 2 of the application form and gives it to a committee member.
  10. If the flight is successful, the applicant’s membership card will be re-issued showing MPR Accreditation
