Whoa, that's a lot of water. :shock: I hadn't seen that video before. Is that coming from the water tower?

Not sure where it comes from, but that's a lot of pressure.

Probably not in the spirit of the current NSW water restrictions.

Here is a video of the rebuild of the sustainer that will hopefully fix the bending problem we saw with the previous one. At the end of the video is an accidental pressure test that points to the upper pressure limit for these airframes. :D



We are hoping to launch this next week at the Mullaley HPR launch.

When good water rockets turn bad, they are turned to the dark side:

Here is the latest video in the series. This video covers the completion of the launcher for this rocket. There are still minor tweaks to do, but we wil now move on to making the actual booster, and then tweak the launcher to suit. At this stage we are not sure on the timing of that but there are certainly things we'll be able to work on. I hope everyone is well and keeping safe.

Thanks for asking Derek. I am just ramping up again after having a short break, I finally received my order (after 5 weeks) from Soller Composites which I needed before progressing. I've slowly been gathering materials to make the booster. I now have everything I need so booster production will be starting very shortly. We are first going to make a short prototype of one of the pressure chambers and test to see how it handles the pressure, and then based on that we are going to make the 3 pressure chambers for the booster.
In the order from Soller Composites I got 12 yards x 42" of plain weave 200gsm carbon fiber cloth, and 33 feet of 3" and 16 feet of 2.5" carbon fiber sleeve.

I've also been working on another rocket project which I'll bring to Whalan on the weekend to see how it will go. It's a water rocket specifically designed for Whalan Reserve and the club ceiling we have there. :wink:

It's been a while since we did an update on the project. Here is the latest set of pressure tests we did on a second test pressure chamber for the booster:

Great to see that Horizon is still progressing, that you are still learning as you go.......and you are still listening to your dad!

And what a great endorsement for Jolly Logic and your soldering skills that you were able to discover Nova's altitude after all that time. Amazing!

Did you ever work out why Nova's chute didn't deploy?
