Re: HPR X Wing - T70
Excellent work Mat! I'm having flashbacks to my childhood when my father would melt lead in a process virtually identical to this to pour lead weights for duck decoys.

Re: Ejection charge cap
Vast majority of flights i use 5ml centrifuge tubes for charges. They're bigger than the 3ml ones that come with AeroTech motors. I've yet to have one rupture the tube, the cap gives way and that's it. I bought a 300 pack of them from Amazon for less than $30 AUD. I'm not a fan of charge canisters a...

Re: Arduino Radio Beacon
Hey DiscountBatman! Apologies for not replying sooner but I do think I've got a point worth making. Specifically, if you're looking to make a radio beacon, you want to stay away from radios that utilise spread spectrum modulation. This is due to the fact that spread spectrum utilises a wider bandwid...

Hey OTT, good to see you working on your VTS again. With reference to the 1.3GHz telem, I assume you've selected that frequency due to COTS kit already available for your FC?

Re: Hobbyking Pulse Jet
Anyone got one of these that they no longer require? I've got a mate that's interested in getting one but it appears HobbyKing no longer sells them.
Cheers.
Cheers.

Re: Vacuum tooling for composite construction
I love your use of the metal tubing to ensure your threaded rods for the fin alignment guide are equal length. I'm going to have to steal that technique!

Re: CTI 38mm Tailcone
If you do a bit of digging in TRF looking at posts from Crazy Jim on this topic he and Charlie Ogino did this YEARS ago (2015?) and it was a "certified" modification in CTI's eyes. IIRC that would have been the rocket you can just see on the Tripoli Single motor altitude records page, entr...

Re: Vacuum tooling for composite construction
Great work mate. I might have a line on some super cheap breather if you'd like some.... Safe to say we know a guy.

Re: Running in the 90's - my Aeronaut Project
Lol, the Bare Necessities fincan folded up like an accordion. No, it did not, It survived the supersonic corkscrew, same for the nosecone. Huh, fair enough. I think we can both agree that the rocket wasn't stable though. :lol: Also, fingers crossed you're not falling down the "optimized" ...

Re: Running in the 90's - my Aeronaut Project
Talking about the design, I've ditched the sustainer's composite fin canister for a "Bare Necessities" style fin can. I'm currently expecting it to weigh less than 550g :lol: , I'm still working on it. Getting it 3d printed in one piece out of aluminum is something I'm considering (with a...

Re: Institutional knowledge
Laminate thickness depends on the type of reinforcement AND the amount of resin. Correct. And the "ballpark" ratio we work towards in the hobby is 1:1, right? And maybe a little less if your layup is under vacuum? I'm not an expert but from my understanding anything above a 1:1 ratio will...
