I owe the SSS pot $20.I must be a glutton for punishment, because I already dreamed up a new and improved version of the SSS rocket. Actually, the dreaming up part is easy and fun. The building and flying is…   Read more»

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.http://www.wunderground.com/DisplayDisc.asp?DiscussionCode=BOU&StateCode=CO&SafeCityName=CarrApparently some of the models they use are predicting around 3-6″ total, and others are predicting more like 1-2 feet, based on……[Read more]

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…   Read more»

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 some estimates. Of…   Read more»

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…   Read more»

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 sampling method, or…   Read more»

And if you think about it, pretty much everyone who did their jobs really well that day are union members. This link gives more details:http://www.dailykos.com/story/2009/1/16/11125/1166/655/684821

Great news John, glad to hear it. We look forward to having you back. This should be fun.That 2.5″ glass tubing and cone sound like the perfect setup for Adrian’s next step up the altitude junkie ladder!Unfortunately, there aren’t any…   Read more»

I’ll be donating some sort of altimeter for the raffle again, but I haven’t decided which model yet.-Adrian

Of course, you could ignite your second stage motors with Parrots in those 18mm tubes, and get apogee deployment and some cool data as a bonus. Might be tough to pull together before this weekend, though. I’ll lend you one…   Read more»

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.

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?

Thanks, Ken.I’m looking forward to flying tomorrow. The Briggsdale winds are forecast to be only 1 mph from 11 to 2, with 4 mph the rest of the day.I know Mike will fly his twins. Who else is coming?My flight…   Read more»

Thanks for your great work, Ray.

Thanks, Joe. We’ll see if I can get my transmitter working properly this time.

In case people haven’t seen the build thread on TRP (http://www.rocketryplanet.com/forums/showthread.php?t=2409) and want something to fill the void,here is what I’ve been working on recently, a new 38mm av-bay. It will have 2 Parrots, a Beeline transmitter, and 2 deployment…   Read more»
