I've supersized my launch tower in anticipation of some larger projects. Now it has 8-foot long 1.5" diameter aluminum uprights, and a new ring at the top that will accomodate up to 10" fin circle di...

You can take the boy out of Iowa, but....😉

If you're a weather nerd like me, you may find the "scientific forecaster discussion" interesting at the Weather Underground. Apparently some of the models they use are predicting around 3-6" total, ...

There's a winter storm watch posted now, with 3-6" likely late Friday night and possible blizzard conditions on Saturday. Sunday looks better, with the storm cleared out. There may be 6-12" on the g...

That would work with the carbon fiber, but don't expect it to work with the Kevlar. Once you've got the kevlar fuzz as small as you can make it, you would need to do an epoxy coat or something to get...

Excellent, Ken! Sound like a fun job.

If you're looking for a range where you don't have to worry much about it, I'd say probably around 1000' for a small A rocket, 2000' for a 38mm min diameter rocket. Above that, others could provide s...

Does the Alt15k do apogee deployment? I wasn't aware of that.

Cross-posted at RP, but this is too fun to keep in one place. Check out this 38mm forward motor retainer I got at Home Depot this evening, for $2.97: I'm sure an enterprising person could also figure...

Is this a 70/35, 30kft version? If so, I have a customer for you, since I'm temporarily out of stock on that model.

It works fine. That's how I did the setup in my 24mm booster and Der Mad Rex. I ran the deployment wires along the shock cord, past the chute, to a piston. Then the charge pushes the piston and the...

Ken, It was an H999.

Thanks, Chad. Usually I like long-burn motors too, but it was quite a thrill to see it leap off the pad like that. So are the oscillations in the 250G meter real thrust pulses, an artifact of the sam...

More fun stats from the Mad Rex's final fight:It left the rail at 150 mph10 feet above the ground it was doing 191 mph0 to 500 mph in 0.225 seconds Peak sustained Gs: 114Peak measured Gs: 130 Peak ve...

It's probably too late to modify this year's alphabet contest, but as a variation for next year, we should have the first tie-breaker go to whoever does their set with the least number of rockets. Or ...
