hey, we're looking to purchase rocket motors for a school project, do we need a permit to purchase rocket motors or is there a size limit that we are allowed to purchase. Is it illegal to make our own rocket motors? :lol: is so where could we source rocket motors from, looking in particular for the f10a motor or is there any other motors with a burn time longer than 6 seconds available in australia.

Making rocket motors in Australia requires a commercial licence.

It’s my understanding that anyone can purchase G motors and below without an issue. Flying them may be an issue, especially something as big as an F. I don’t know what rocket you are planning to use but flying at altitude will require CASA approval and possibly approval for whoever owns the land you fly on. Plus you are going to need a large recovery area, most school ovals will not be big enough for that motor. Also insurance is a consideration.

Not sure where you are but joining a local rocket club will be the way to go as they have already sorted these issues.

For a school oval launch, something like an A or B motor would be more appropriate and depending on your circumstances should get you around the aforementioned issues.

Blake from Australian Rocketry has far more knowledge of the rules and can supply you with appropriate motors.

Making a wild guess, but if you are looking for F10’s you are possibly trying to do Thrust Vector control cos you’ve seen it on you tube.

Those motors are not readily available in Australia. If you do a simple search in this forum, you’ll see the question has asked on more than one occasion by people with the same aim.

Certainly agree with above comment. Join a club and get the basics of model rocketry sorted. Your questions would suggest you don’t have a working knowledge of the subject.
