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) Assessment 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 assessment 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
A member applying for MPR Assessment 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
- Provide evidence of experience in low power rocketry to a committee
- Determine the weight of your completed rocket. Note: RTF rockets cannot
- If the rocket is scratch-built, evidence of its stability must be
- Use 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
- On the launch day, fill in a flight card and complete section 1 of the
- Give the application form to an approving member.
- Assemble the motor (if a reload) under the supervision of the approving
- Present your rocket with the flight card for inspection by the RSO.
The RSO will assess the rocket and its construction, including ensuring that
it is stable. 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
- Launch and recover your rocket.
- Present the rocket to the approving member for inspection.
- The approving member completes section 2 of the application form and
gives it to a committee
member. The decision as to whether the flight merits achievement is at the
discretion of the
approving member and the committee.
- If the flight is successful, the applicant’s membership card will be
re-issued showing MPR capability.
