I have some battery connectors on their way, and when they arrive I'll make the booster electronics panels. Then we need to start thinking through the 2rd/3th stage electronics in earnest. I have a...

So you're ready for booster electronics, then? Do you have a spot to incorporate a panel with altimeters and batteries for the booster cluster ignition? I can do it in one or 2 panels. I'm guesst...

For the bolted interface, I would suggest to design it so that the airframe tube of each section is butted up against each other and the nylon bolts just preload that interface. That way, as long as ...

For the exploding bolts, I'd recommend Quest Q2G2 ignitors because we can run as many bolts in parallel off of one electrical output as we want. For the booster, I could make up a couple of small plyw...

Thinking outloud here and thinking towards a worst case scenario, of the three main motors, only two ignite in the booster, and only three of the 6 outboards ignite, and they are all on basically one ...

To maximize the chances of all 6 outboards lighting, and minimize the consequences of one failure, I would use 2 Raven altimeters to give each outboard its own channel, battery, and arm switch. Then t...

O.k., so light all 6 outboards on the rail at first motion, then stage separation, then light the sustainer, right? What size for the outboards? Are you still plannnig for a K sustainer motor? I'm p...

What's the current plan for the airstarts and electronics? I have a Rocket Tiltometer from Frank Hermes on the way that I should be able to loan for this if needed. But if the outboards are just goi...

You can get tungsten powder from Amazon, but it's not all that cheap. People use it for weighting golf clubs. It's about $15 for 1/2 lb if I recall correctly. It's a pretty easy way to shave 1/2" o...

Thanks, Warren, for accepting the correction of this misunderstanding with such grace. No hard feeling here.

Apology accepted, Warren. I know you have been doing your best on this and your heart is in the right place. There is one assertion that you are making that is incorrect, however, that I think has b...

I'm reposting what I wrote on another thread, with minor mods, because it's relevant here and it might have been missed before: Different people get hooked on rocketry for different reasons. For me, t...

I've had a lot of flaws in my scratch tubing too, but they've been mostly cosmetic. I'm making my own tubes for 2 reasons: I like using mostly axial unidirectional fibers for more efficient tube ben...

I deal with ITAR issues all the time at work, because all specific technical information about spacecraft designs are covered. I'm not a lawyer, but I'm pretty sure that there's nothing we're discuss...
