The fins look great OTT! Good luck with the flight, I'm very much looking forward to the flight report. How do you think the fins will go on landing?

Here are the next two parts of the series. Part 5 is about building a test stand to apply forces (up to 10kN) to different components before we subject them to compressed air. v5f0stjvqLE Part 6 describes the overall launcher design and also how we made the release head that holds down the entire ro...

Sounds like a great design. I will definitely be following the build thread.

Hi Derek, Welcome to the forum and back to rocketry.

Very interesting update on this project OTT. Wow, 140W is quite a bit power to have on hand when needed. Interesting problem with the negative G-s. How will you determine when it is safe to start trusting sensor after burnout? Also when the servos are in their neutral position, are they actively bei...

Thanks for the nice words OTT. Dad and I are having fun building this rocket together.

It's been a while since I have updated this thread. We're continuing to make good progress on this rocket, and with Thunda less than a year away we need to push a little more. Here are parts #3 and #4 of the series. Part #5 should be out next week.

That's great! Very well done Congratulations on your L2!

I'm all ears! Do you have a reference for the 55-degree number? I heard something similar before but could never find a source. I would also be very interested to understand how you are estimating your case strength and how this is stacking up against test results. One of my big questions right now...

Thanks for sharing all the great details of your build Mike! Looks a like a fascinating project. Would it help to cool the mandrel with ice when extracting it from the tube? I am looking very closely with what you do with carbon fiber casing, as we too are in the process of making some high pressure...

Here is a highlights video from the Saturday launch.

Hi guys, Here are some photos from the last launch at Mullaley. We had absolutely beautiful weather with blue skies, little wind and nice temperatures. There were some pretty spectacular launches, as well as some sub-optimal ones. http://www.nswrocketry.org.au/gallery/2018_Launches/Mullaley_2018_05_...

Wow that's awesome. Congratulations on a great flight Mat. How did the performance compare to simulations?

Cheers guys.
@SpaceManMat - That's why dad was wearing an old Helmet, eye protection and earplugs. I don't want to get anywhere near that thing. One day we'll get confetti. ...hmmm .... that will have to be the name of the next rocket ... "Carbon Confetti"

As it has been a couple of years since we last flew this rocket, it was time to dust it off again at the last Mullaley launch. Here is a highlights video from that flight: fvebpl3W1Sg We are still not sure what the upper pressure limit is for this rocket, though some recent ground tests on similar p...
