Well said, James and Steve!

My prep is going way overtime, so now I’m planning to come up early tomorrow so I can keep working tonight. I have range duty in the morning tomorrow and then I’ll be free to install the electronics sleds in…   Read more»

Hey Gang! We have a bit of a snafu with the planned parachutes and may will need to do some scrounging. We had planned for a 16′ or so chute for the booster section .. about 80 lbs .. but…   Read more»

I’ll make time to come out sometime this weekend to help finish with the electronics.

I’m going to finish up the booster electronics panels and then deliver them today, sometime between 10 and noon.

Could the project make use of a SkyAngle deployment FreeBag?, XXL (10″ x 17″)? I won it at the rocketry dinner and I don’t see myself ever using it.-Adrian

I could see using the Missleworks radio for the 2nd stage ignition and then using the TiltoMeter for the 3rd. Does anyone have one that they are willing to lend for this?-Adrian

Update on the electronics: In communications with Frank Hermes, his TiltOMeter can’t provide tilt checking for more than one event, and he’s not interested in making firmware updates that could let it be used for more than one. The Featherweight…   Read more»

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 tiltchecker now, but I haven’t powered…   Read more»

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 guesstimating now that it would…   Read more»

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 the preload from…   Read more»

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 plywood sleds that have…   Read more»

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 side so that a…   Read more»

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 there would be 2 booster channels…   Read more»

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 pretty sure the ban on the…   Read more»

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 going to be…   Read more»

are there any repositories of known HPR webshops? I’m considering the possibilities of starting yet another HPR-based web business, and the next step is estimating the cost of advertising.www.rocketryforum.com and http://www.rocketryplanet.com are both great places to let people know about…   Read more»

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 been at the…   Read more»

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, the idea of flying a rocket higher than…   Read more»
