If that is a 24mm rocket (hard to tell?) and if it was calm (I wasn’t there) and if it landed 3 miles away? Then that was a MONSTER boost, record or not!The picture is of a 24mm booster, built…   Read more»

Sweet!That’s my booster that I flew as a single stage on Sunday after my sustainer failed to ignite on Saturday. It looks like the altimeter and transmitter broke off or something, though. 🙁 But i think I threaded them onto…   Read more»

I’ll be happy to head out to the North Site and help you look, and maybe you could throw a few rocket design technique bones my way.Chad, that’s a very generous offer. I wasn’t sure I was going to go…   Read more»

THANK YOU very much Adrian!!!You’re welcome, Doug. Those booster attach fittings were really interesting. I couldn’t figure out how they worked.Adrian,What day and time were your launches? I ask because my launch to 4600′ on Saturday at 2pm indicated more…   Read more»

Your found item sounds like one of the boosters for Doug Gerrard’s Freeze Frame.KenAnyone find my Wacky Wiggler yet?

Yep. It was back at the LCO table on Sunday afternoon.

It is Doug’s, I have it now and will see that he gets it.any idea were you found it?Go to maps.google.com and in the entry box for “search maps” type in “doug’s booster.”. I’d post the link here directly except…   Read more»

Here’s an update on my little 2-stage 24mm rocket:I’ll fly it with an F28-E6 combination on Saturday, which could go 9k-10k. Then if I haven’t lost it yet, I’ll put a bigger motor in it, G37-E6, which could go over…   Read more»

If I can get it done and sufficiently tested, I’m going for the G staged record with a G37 to E6 rocket. See http://www.rocketryplanet.com/forums/showthread.php?t=1999 for more info. When I was planning smaller fins it simmed to 15kft. Now it’s more…   Read more»

I’m planning to be there at Octoberfest. I’ll help you set up Jim Yelle’s download program. I also have some formulas you can use in Excel to remove the extra lines; I was just hoping to get you a cleaner…   Read more»

Having “Append line feeds to incoming line ends” selected could be the problem. Try de-selecting that and let me know if that fixes it.

Mark,Jim’s program looks at a batch file that’s among the files that are zipped up to see which port to use. You have to modify that to match whatever port number the Parrot gets hooked up to. One of the…   Read more»

I have been using excel 2003 without any trouble so I don’t recommend going back to Excel 95. I did take another look at the hyperterminal settings under properties/settings/ASCII setup, and there is a selection box for appending line feeds…   Read more»

I haven’t run into this myself, but I have heard from other customers that this is a problem with the newest versions of Excel. If you don’t have a previous version of Excel available, there are a couple of other…   Read more»

Thanks, but it doesn’t count since part of the rocket wasn’t recovered. I’ll probably try again for the G record on an Ellis G37 later this year. I’m thinking about going for the G-impulse staged record also, with a G37-E6…   Read more»

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

Glass with high-temperature epoxy would do just fine for the fastest, hottest flights. The hobby store fiberglassing epoxy I used on Barack-it got noticably softer around 120 F. Aeropoxy is one of the higher-temperaure epoxies in common usage and it’s…   Read more»

I agree that the epoxy will be the limiting factor for any of these, but wouldn’t carbon and glass both be more heat-resistant than Kevlar? Both are refractory materials, particularly carbon-carbon composites. Glass melts at 1400C. Carbon is nice for…   Read more»

Not sure about the temperature, but keep in mind that it can’t be sanded, unless you want your rocket to look like a sweater, that is.

I think I’d use barbecue paint on that bird….What kind of temperature is the BBQ paint good for? I was thinking of just using cotronics epoxy and thin FG for the finish. No primer to run. I’ve checked out the…   Read more»

I don’t know about Rocketwhiz, but what I had in mind was just a top speed record, a la Mach Madness at LDRS. Featherweight Altimeters is sponsoring a prize for that, by the way. Integrate data from an onboad acclerometer…   Read more»
