    Wanted 38mm Giant Leap Threaded Closure?

    Is there going to be anyone at LDRS40 with a 38mm Giant Leap threaded closure for sale? I have lost the threaded ring to my 38mm SLIMLINE BELL-SHAPED NOZZLE RETAINER and will gladly buy the whole retainer even though I only need the 38mm threaded ring. I still have the tool, but managed to lose...

    The Anisoptera -- A Home-Built Camper

    In another thread, there was some interest in my home-built camper that has been seen at launches from Argonia to Balls, and everywhere in between. I am creating this thread to show some build photos and as a place for others to post any photos they may have of this beast. The whole thing is...

    3D Printing PETG Glue Initial Testing

    As if we didn't have enough glue threads... I've been building high power rockets that include 3D printed parts for some time. I've migrated from rail buttons to electronics sleds to airfoiled fin edges, and am now looking at complex centering rings. Almost all of the rocket stuff I print is...

    Saturn V Stability

    I have 3D printed a 1/50 scale Saturn V and now I'm modeling it in Rocksim to calculate how much nose weight will be needed to make it stable. When I look at the Rocksim file provided by Apogee for their 1/70 scale Saturn V, I see that they have taken the profile of the F-1 fairings and created...

    U.S. Rockets Stiletto

    I've had this mostly built (like many of my rockets) for a number of months. I finally got around to finishing it up today and I think it turned out pretty well. It weighs 1200g without motor adapters, parachute, or motors. It's way too heavy for the 4xD12s on the recommended motors list, but...

    Mach1 Saberhawk Rocksim

    The Mach1 web site has an Open Rocket simulation for this fiberglass BT-55 rocket, but not a RockSim file. I downloaded and ran Open Rocket, and I can open the simulation, but when I try to "Save As" a RockSim file, it throws a Java exception. Has someone out there already done this conversion...

    EVENT LDRS 39

    I have been tasked by the Utah Rocket Club to create an official LDRS 39 thread, and this is it! Planning has already begun and at this point I can confirm that the location will be the Bonneville Salt Flats and that we will be launching from Thursday, July 30th to Sunday, August 2nd. As more...

    Reason #934 why I hate friction fitting motors.

    I had a 3 x 24mm cluster booster staging to a 3 x 24mm cluster sustainer. There were no motor blocks or retainers and the two stages were held together by the sustainer motors intruding by an inch into the booster motor tubes. As you would expect, the design relies on each black powder booster...

    Mixed BP and APCP clustering

    It looks like I may actually get my Sirius Saturn V done in time for Hellfire. I built it as a cluster with the central 38mm surrounded by four 24mm motor mounts and I plan on flying with the recommended I284 and four E12-0s. I don't have a lot of experience clustering a mix of BP and APCP...

    Sirius Saturn V Mini Build Thread

    I was lucky enough to grab one of these off the forum so I thought I would post a few pictures of my build. After looking at all the other build threads on this kit, I've decided to stick very close to stock. I plan on substituting Blue Tube (already had on hand) for the 3.9" airframe and...

    Cluster Duck

    Got two great flights out of my Cluster Duck on Saturday at the UROC Cinco de Mayo launch. I planned on building a boost box as described on https://bpasa.com/Cluster-box.htm, but didn't get it done in time. I went ahead and followed Boris and Paul's advice and wired the seven motors in two...

    Replacement BSI Epoxy Caps?

    Does anyone know of a source of just the screw-on caps that are used on 5-minute hobby epoxy? Not just the tiny push-on part, but the whole screw on lid/cap. I have a new bottle of resin and hardner that are plugged but have no caps, and I don't want to use my messy old ones. It seems that these...

    Cooper Development Corp Logo

    Does anyone have a copy of the logo that was on the sides of the Point Defiance Nike-Asp's? I could create it from the ROTW image that's about 2" across, but if someone has already gone to the trouble, it would save me some time. It looks like John Coker had it on his 5" model from the early...

    Lego Saturn V's in stock...

    ...at the Lego store: https://shop.lego.com/en-US/LEGO-NASA-Apollo-Saturn-V-21309 I had two in my cart, but chickened out and ended up just getting one for me for Christmas.

    Crowd-sourced Image Interpolation of Aerobee-Hi

    OK, I'm finishing up a Cosmodrome Aerobee-Hi, based on the round that appears in the Life magazine "Aerobee Hi Shoot For Space Frontiers" photos, currently hosted by Google Images. There are many awesome photos clearly showing many of the markings, my only remaining hurdle is the booster fins...

    Aerotech I59 Issues

    I have two Aerotech I59s that I would love to fly this weekend at HellFire. My problem is that the last TWO times I flew this reload, my rocket and casing were destroyed due to burn through. Two years ago it burned through the case just above the aft closure, maybe half-way through the flight...

    Composite Camper?

    It looks like our old faithful truck camper is starting to fall apart at the seams from a roof that is leaking all around the edges. We were planning on building a new camper, maybe based on the Glen-L plans, with a traditional wood frame, luan interior, aluminum siding exterior, and then moving...

    Alphabet Contest?

    I have an idea for an informal contest at that involves flyers launching the most "letters" of motors (1/4A - M?) on the fewest possible rockets. I need a formula that works out so that launching a single rocket (say an Alpha) on a single class of motor (say an A), doesn't help your score much...
