Re: SpaceX details its plans for landing 3 Falcon Heavy boosters

Yeeehhaaaa. That was spectacular. :D I heard someone mention on a live stream that they had overheard the announcer say that the central core was lost at one point. But can't confirm. I suspect that is the case because we would have heard otherwise that it was sucessful. Still there is a Tesla float...

Re: Horizon - 2 Stage Water Rocket

Here is the next installment in the series. In this video we discuss the design concept behind the staging mechanism for the rocket. We also do a couple of low pressure test flights to test the concept. zT-8YG1hTyA In the next video we'll have a look at how we modify this design to work with the Hor...

Re: Devilish Project (Go Devil 38 kit bash)

Looking good OTT. How fast are you expecting it go if you needed to upgrade the fins? :D You mentioned you went through a couple of blades when cutting the CF sheet. Is there a preferred cutting blade matrial for CF? I've gone through a few blades as well.

Re: Nsw Laws About Water Rocketry?

Hi Laurie and welcome to the forum. You are right there are no clear regulations relating to water rockets specifically as far as I know. In their absence we follow the regulations specified for normal model rockets. This includes total impulse limits, altitude limits, proximity to airports, etc. Th...

Thanks for posting crom. :) I am not sure why we made the list, I reckon the Victorian V2 should have been on the list instead.

Filming rockets at apogee

Over the last couple of launches at Whalan Reserve we've had a go at trying to film a rocket from a drone as it flies up to apogee and deploy's its parachute. Here is the result from the five attempts:

Re: Just to say hello

George: I write to you from the State of Iowa, USA. I am getting started in water rocketry after having retired recently. I find it a satisfying experience. The launches are fun, but the planning and building the rockets and launch equipment are just as enjoyable. I have found your information to b...
