Re: SunSeeker II

Hi Mathias. Looks like a great project. Looking forward to seeing it fly at Thunda! Don't forget to run a thin bead of epoxy on the GPS antenna on the TeleMega. You need to glue the ceramic to the printed circuit part with a thin bead. Under heavy acceleration the antenna can rip off (problem with a...

Re: Joe Turners L2 Build Thread

[youtube]Another question, does the ejection charge damage tubular nylon much? [/youtube] I use TN, but the sections near the deployment charges are sheathed by nomex protectors. That section of TN is also considered consumable to some degree. I would also z-fold the harness. There is a discussion o...

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

Sadly it was visual only, as the couple of hundred km between us pretty much damped-out any rumble. I don't have a particularly good camera so I just enjoyed the sight from the beach. Nice to see though. Maybe someday I will be a little closer.

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

Falcon Heavy has had a successful static fire of it's engines. 20180124-hotfire-678x381.jpg Some video here: https://twitter.com/SpaceX/status/956236301275054080 Sadly I have returned from Florida and obviously the static fire did not happen whilst I was there. I was hopeful, but the universe usual...

Re: Smallest data logger??

Ravens immediately sprung to my mind. Great little units. They are good to 70G. They used to do a 250G unit but to get that functionality nowadays you need to change out the accelerometer device for the higher accel unit (but get reduced resolution as a tradeoff). I am in the process of doing that c...

Re: Featherweight GPS Tracker

I would have probably purchased a pair of these already but they are only Apple so far. I am allergic to Apples. An Android version is in the works I believe.

Re: Are there any beeline users out there?

The Baofeng is quite a good transceiver. My previous manager ran a suite of tests on it (he is an RF engineer) and said he really couldn't fault the performance. If you are using it for tracking, keep in mind that the signal strength meter is not really functional. If you use something like an exter...

Re: What is your project for Thunda Down Under 2019?

Thanks Drew. I am looking at making my own HEI adaption and have been considering it for a number of years. It will, of course, be based around materials and methods that are up to the task.

I have a few other ideas around the safety theme too, but I don't want to hijack the thread too much :) .

Re: What is your project for Thunda Down Under 2019?

Thanks for the comments Drew. So that is the official AMRS stance on HEI? If so, is it documented somewhere, and what are the requirements for using other HEI setups other than the CJ system? Agreed. HEI is definitely not the main safety issue for staging. Not so bad if things go awry up at altitude...

Re: What is your project for Thunda Down Under 2019?

What is the official statement regarding the allowability of HEI (head end ignition) at the Thunda event? Is it a proscribed technique? Is it allowable with certain caveats? Some info on this would be great as there are a few multi-stage rockets to be flown there by the looks of it.

Re: Drama Queen

Welcome 03flyer. Yep This hobby is addictive, especially once you see the HPR stuff.

I notice you have Nikola Telsa as your icon. I will be traveling to Europe in a few months and will be visiting the area where he lived and the museum there.

Re: Rocket Lab prepares for Electron test launch

Congratulations to Rocket Lab :) :) :) . That's twice NZ has beaten Australia to space. Shows what is possible when given support at government levels. Their first flight would have gone orbital too, if the ground tracking equipment had been configured correctly by the external contractor providing ...

Re: Newbie / Oldie

Welcome back to rocketry, and to this forum, Kelstra. Given you are in Melbourne I will probably catch up with you at a launch sometime.

Lots of great information around here. Enjoy!

I was just up close to this pad yesterday :)

Spent three days at KSC so far, and another half a day today will be the end of it for me. Lots to see.
