Thanks to everybody for the replies. Appreciate the varied perspective on different brands, very good to know as this is a significant investment. As far as the "wait, you're not a middle aged man doing this in your suburban home with a garage? This sounds like a cause for concern" comments...

When you're three years out of college paying market price, out-of-pocket for every piece of every project you pursue, you become prohibitively frugal. When it gets so bad that you're spending your Saturday nights following a Craigslist ad to a storage unit an hour outside of town to try and...

Email sent. By my count, I'm #9 to respond, so hopefully there's one left for me. Thanks

13.5k/11.5k = 117%. Not a sterile experiment by any means, and not even my data - but serves as contextual validation in the residence time debate, among other things. Randito's historical favorite formulas are 68/10, catalyzed Mg/Zn white, and Blue 22 (78/2/2), so pretty middle of the road in...

Apologies for the vapid update, but I'm hoping to keep this current, and today is my deadline for over 50k', so no time like the present. Three weekends ago, Manny and I totaled 4 hours of sleep, and it took four days to reach that total (Friday-Monday). I added 860 miles of driving on top of...

Replied, thanks Nick. SPF

Traveled back east this weekend to help my dad fly his large two-stage project in single-stage config. The project was years in the making and the sustainer suffered an early ejection and as such recovered with no chute, so the booster electronics purchased for the eventual two-stage flight are...

You guys are talking about it, so their mission is accomplished. Love the double entendre - the whole selling point of gaming systems is living vicariously through the game's graphics, so why not extract the same attraction for the ad campaign? My boss always says, if you have to mention...

Haha, James is an old friend of mine and taught me everything I know about building high performance projects with hand tools among many other things. Just posing a generic reply as I've gotten a a few inquiries all asking the same thing since that pic was posted.

Precisely. It's interesting, I'm surprised this has caused conjecture on the forum and elsewhere, with the common misconception being that we mixed a random amount of properly ratioed trimodal oxidizer, shook it, and measured out the amount of total AP from that bucket, with the resultant...

I'm normally not the type to load my projects up with gratuitous electronics (there's a distinct demographic in rocketry with the opposing viewpoint, I've learned) - but TINY (my most recent high-alt project, build thread in HPR forum) intentionally sacrifices a bit on mass fraction due to...

Shoot, and here I was thinking it would be Crossfit-themed.

The dominoes are starting to fall here. We have our ossified parameter now - the actual tube - so we can get building around it. Spent a couple hours last night mulling my final propellant config in the gym, where all the best design work happens, and consulting some friends before freezing...

Without getting into a jovial review of the constitution, being in a position of having to justify to the BLM how information was disseminated and having to explain who knows who, and how, isn't something I think anyone would want to sign themselves up for. Best case, it'll be an added stressor...

Gus Piepenburg's 5.5" FWFG rocket (60lb pad weight) on an N10k 11 and change per the Telemetrum, I think MB posted the data earlier in this thread Perfect recovery about 100yds off of FM1950 -sh

Despite the fact that the forum is generally indulgent with hyperbole (which I try not to participate in) this is objectively the coolest thing that's been posted on here all year in terms of innovation, engineering, self-sufficiency, execution (machining) and outcome. 408 views...crazy...

Dan - this is what I was referring to.

Wilson ran my geometry in those motors, so I can attest that it's just fine. Perfectly concentric cores help too, he'll get there. The source of cooking here is likely paper liners while loading up on metals. Wilson - like we talked about, I'll use over 1.5x of your metals loading here in your...

Took a sardine can flight up to Chicago over the weekend to see some friends in Chicago and hit MWP with Manny for a few days, and there were some developments on this project as a result. First, got my liner in the mail on Thursday - one sexy piece of phenolic (well, actually two). Seeing...

Hey Barkley, Thanks for the suggestion - I haven't called Metal Supermarkets. If I'm going to mail order the tube (or have them mail order the tube), I may as well get it from Online Metals - cracking the code here would mean hunting around a warehouse for something that's just out-of-spec...
