    DYNACOM KIT INSTRUCTIONS & MORE !

    Eric, I have a few fins left over from the booster stage of our LDRS 21 T2 if you want an original or two for yours! (I think two are fully intact, but I'll check Thursday.) And nice Anaconda pics in this thread ;) Thanks for the deal on that one, Gary, I'm honored to be the one who's keeping...

    Midwest Power 17 - Nov 15-17, 2019

    I knew that guy couldn't be trusted as soon as I put the motor in his car. I mean, come on, just look at him :p Finish that deck while you've got the weather for it, don't worry about me! Can't wait to be back in the fall fields. (It's supposed to be 90 here today, yuck.)

    Love coffee

    Local roasters, for sure. My regular supply comes from YES PLZ, they're off La Brea between me and my office so the coffee is always super fresh, plus it comes with a free zine. My supply is synced up to get delivered with their music issues, which I love. When I'm in Brooklyn, I always grab a...

    Midwest Power 17 - Nov 15-17, 2019

    I'll bring a spiral snap ring that fits in an Aeropack tailcone if you bring that Sconnie Sparky again :D I also owe Chuck some video footage and Amy a Punisher race. Beyond that... just amped! Can't wait to see y'all again!

    Nice flight! I love Blue Baboon :)

    Has anyone else noticed a change to the way CTI is producing 54mm motors?

    Maybe it's just me being a grouchy old TAP, but this attitude ain't the recipe for success. It's ultimately the flyer's responsibility to understand and verify the form, fit, and function of your vehicle's components, CTI's advice or no. NFPA 1125 8.2.6 requires the reporting of "changes...

    Anyone visted SpaceX headquarters in Hawthorne?

    Yep. Orbital ATK donated two empty SRB hardware sets, and they've already got an external tank. More info on the campaign is here. Take the Expo line and enjoy an LAFC game while you're in Expo park, and (if you ask nice) maybe even a tour of USCRPL. SpaceX has good froyo.

    Has anyone else noticed a change to the way CTI is producing 54mm motors?

    I can never keep track of which motors use pellets and which don't, so I have a trick. I pull the forward bulkhead out (like I'm gonna drill the delay) and look to see if it has a pellet. Then I choose an appropriate motor starter for the situation. Then I fly it :D (Don't forget to put the...

    Princeton University attempt at a suborbital space shot?

    Spotted in the wild last night.

    Old AMW propellant

    Demon 6 (4 fins, natch) :) Pics in the Balls thread. BTW, on the topic of o-rings: Buna-N or Silicone will both get fried on the nozzle from the heat soakback with high-output loads--Paul and Frank liked the silicone ones because they were easier to get into the case. If you've got Buna...

    EVENT BALLS 28

    Ain't that the feeling! :) Had a great time at Balls. Flew an L, an M, and an N, didn't make any groundbreaking discoveries, had fun, but more importantly: Guided Tim through easy (and hard!) Black Rock recoveries (with a major assist by Tony!) Caught up with so many people I haven't seen in...

    Old AMW propellant

    The increased surface hardness is not a surprise; the thing that makes the flame blue also encourages the binder to react with the surrounding air, leading to faster aging. Blue Thunder has a similar problem, though to a lesser extent (it's a slightly different thing). I wouldn't worry too much...

    Wildman's MACH 2 rocket

    Nah, very normal. Tim cuts tubes to length on a chop saw, so there's always a little bit of unevenness. (I keep telling him to do them on the slotter but they'd take a lot longer that way!) To get things even, you can do the paper/sanding block thing, or--as Griffin taught me--stick a coupler...

    LOC Hawk 7.5'' Build Thread

    Ayii, logging in for the first time in a month--sorry for not getting back to you before the last launch! Yes, the deflector slips out, you just pull straight up--there's a pin on the back that slips into a receiver on the pad. Drop it on the lakebed right under the pad so you still meet the...

    LOC Hawk 7.5'' Build Thread

    Since I started taking the deflector off, I've flown lots of Ms in 40-60 lb 5"-6" x 10-12 ft rockets off those pads with no issue. They're heavy and have a nice, stable, wide footprint. The big fins on the Hawk may have been a challenge in the breeze--I bet the pad scooched around a little as it...
