As for launch dates, we have set the calendar but are waiting for final approvals to come in for release. Thanks for your patience. It should be rewarded with lots of dates this year :) .

Re: Newbie: Make your own rocket from scratch or buy a kit?

Hi Kae, welcome to the forum! You can try making a "scratchie" if you think you have the skills, and buy (or scrounge) the materials. Look up "swing test" to see if it is stable before you fly it. Parts are readily available from Australian Rocketry. The advantage of buying a kit...

Looking for uMAD Documentation

Does anyone out there have documentation for the uMAD (micro magnetic apogee detector) that Whooshtronics produced a while back? I am having trouble finding schematic diagrams and operating instructions.

Thanks!

Re: Greetings from Sydney

Welcome Garonious! Sounds like you might have done something in the radio astronomy field for work? Interesting stuff. Aiming for a PhD in ion or plasma drive maybe? In learning aerodynamics etc are you familiar with "Fundamentals of Aerodynamics" by Anderson? I found it to be a great book...

Re: Importance of an inner motor tube for high powered rocketry

Hi Shepherd. Welcome to the forum! I have pondered the same question myself. In LPR I think it adds structural strength and makes it easy to mount a motor hook onto. In HPR it can also add strength and spread the motor forces to the airframe more evenly. If you can get the forces to the airframe wit...

Final Preparation for Thunda2 Here we are, within three months of Thunda2 where this stack will fly :) . Final preparations for the rocket are underway, and p...

Re: I Need a Nosecone!

What is your expected flight envelope? Max velocity? I have a 3D printed design that I personally would fly up to low supersonic (<M1.4) if printed in ABS. Details here: https://forum.ausrocketry.com/viewtopic.php?f=6&t=5019 I have probably around two dozen flights on it so far. I can send you t...

Re: Batteries needed for Thunda

Welcome Jonathan, My experience shipping LiPos when traveling is to take them as carry-on. They are not allowed as checked baggage. Personally if I were traveling with some of those LiPos (not particularly large) I would put them in one of those protective bags you can get for use when charging. Tha...

Upscale to M motors and if it survives the centripetal forces it would go orbital!!!
