Looks like a beautiful machine, and it should be a blast. Any way to check the stability on it? There’s lots of fins, but lots of motor weight back there, too.

Also you might need little beefier moters than “B”s in the bottom. I think it looks like you have room for “D”s :)I’m just throwing out concepts, and I don’t want (or want any of the helpful NCR members) to…   Read more»

Just a little more complicated than my 5 stager starting with a 4 “D” cluster. Ok a lot more complicated! In mine, if the center “D” didnt light, it would have been a much shorter ride. And no deployment….   Read more»

Clip whips or flash in the pan for the first stage ignition? Either way, kool project.

Model Rocket version of Cradle BoosterI had some down time up at our cabin, but brought some model rocket parts up with me. I made a model rocket version of the two-stage cradle boosted rocket which would use three (3)…   Read more»

Great idea Mike. Can’t wait to see it fly. Hold off until warmer weather would ‘ya? Given the current weather forecast, I don’t think 1/3 is going to happen for me.Warren

Was the motor retention your own scratch design, or was it part of a kit?Thanks, guys. This retention methode was my idea, as there was no room at the rear for the typical Aeropack retainers, plus the sustainer has a…   Read more»

Way cool, Mike. I love it. Kind of like a launch-able tower.Was the motor retention your own scratch design, or was it part of a kit?

That really looks cool. I want to start getting into multi-stage rockets this year. Bring it to the meeting, I would love to see it and ask you tons of questions 🙂

Brian! Did you manage to dig your computer out of the snow up there? How are things going? Give us a report from up North and a little to the West.Art

Merry Christmas everbody

I may be hanging out in FC over the weekend, I’d be up for catching up w/ some rocket geeks?JW

Whitney’s flight was delayed, but he should be in CO now and is skiing for a few days. Email him and hopefully he can connect with a few of us later in the week.

Come on folks – this is a fellow rocketeer from another state. Let’s get it together and have a nice visit with Whitney over a few beers, talk rockets and projects and so forth. I for one would be up…   Read more»
