A friend and I spent much of 2023 designing, testing, and building a rocket that uses the carbon fiber body of the rocket as the motor case, and finally got to launch it at the end of the year. Not everything went perfectly as you will see in the video, but this was still the highest performance...

I've wanted to build a filament winder for years now but always considered it to be too daunting a project, given that building one includes mechanical, electrical, and software work, not to mention lots of messy composites. Examples of homebrew winders are few and far between with no real...

I recently had the opportunity to bring a project with me to the Friends of Amateur Rocketry launch site near Los Angeles. Both because FAR is great for high-performance projects, and because the rocket had to be shipped across the country, I chose to do a compact, high performance build. I had...

I'm trying to track down some tender descenders, especially the L3 version. Let me know if you have one that you're looking to sell.

I'm the chief engineer for the MIT rocket team this year. We're working on improving on our rocket from last year, Hermes I, which flew to 33kft over the California desert on a student built and designed 6" diameter O motor. We hope that Hermes II will exceed 80kft as we continue to build on our...

Does anyone have experience with satellite-based asset trackers like these units? I have an Eggfinder and have used it successfully, but range results I have heard of people getting with the system makes me wonder if it would work in the case of a main-at-apogee on a high-flying MD project...

If anyone has either a 75mm flanged AP retainer or the 54mm->75mm adapter sitting around for some project that they never got to build, I'll take them off of your hands for a bit under retail. I'll order them from Wildman by the end of the weekend if I don't get any offers on here.

I was the vice president of the MIT Rocket Team this past year, during which time we worked on our largest rocket yet. In one year we characterized a new propellant, fired our first successful 4" motor and a series of 6" motors, laid up our first carbon fiber fin can, and developed a dual deploy...

I got my L3 yesterday at the MMMSC launch in Berwick, ME. Like my two other certification flights, I used a scratchbuilt rocket that included many custom parts. As shown in my cert doc, the rocket is 6" in diameter by 11' in length and is made from G10 tubes that I laid up myself. I used an...

I'm looking for a main parachute for my 30 pound (dry mass), 6" diameter rocket but I'm running into serious indecision and could use some help. I could go with a TFR 120", because it is cheap and just a larger version of many of my other parachutes. I was hoping to get something with fewer...

I'm looking to pick up a used-but-clean 75mm reload adapter system or AT-compatible forward closure. I'm definitely open to either the RAS or the FC, but I'm more excited about the RAS. I'm also on the lookout for a seal disk, and would be happy if I could get both from one source. PM me with a...

I'm looking for hardware for an eventual L3 attempt. I don't really care what brand/diameter it is, as long as it can fit a certified M motor. My ideal case is an AT-compatible 75/5120 because it would let me fly L3 and the upper L2 range, but I'm open to any hardware if the price is right. I'm...

I'm current trying to build an N2000 in a generation 1 CTI 6GXL case and it isn't going particularly well. It seems that the reload is one o-ring too long and I can't get both closures screwed in. Any suggestions? I have watched the AT 75mm crossloads video and assembled the motor using it, but...

I'm planning a relatively stubby 5.5"x69" build that will have a central 54mm motor mount and a pair of 29mm mounts for airstarts. Due to the length constraint, and because I want the primary deployment altimeter (an RRC3) to fire the airstarts, I would like the rocket to have one avionics bay...

I finished my quarks a few weeks ago but just got around to testing them. I started with the serial barometer test, but I am curious if the results that I am getting are right. I followed the procedure in the manual and on both of my quarks every serial monitor that I try is showing a sequence...

I just picked up a shiny new Loki 38/480 case and a handful of reloads (2x I405 and 1x I210) that I can't wait to use! I was curious about what other people use for igniters with these reloads, as none are included. I was looking into getting a kit to dip my own from quickburst, but that...

My 18th birthday is approaching quickly, meaning that my Jr. L1 is about to turn into a regular L1! This is exciting because it means that I will finally be able to prep engines at home and will hopefully be able to fit more flights in per launch. It is also awesome because it means that I will...

I placed an order with Wildman close to 3 weeks ago and haven't received anything (not even a shipping notification). I have tried calling and emailing and got no answer on either. Is something up with Tim? I know he was busy with LDRS for a while, but that was only a few days around the middle...

About a month ago, I was fortunate enough to go to L.A. to participate in the International Science and Engineering Fair. Lots of amazing stuff there, and my team ended up doing very well. There wasn't a large number of rocketry-related project to post pictures of here, but on the last day of...

I emailed Robert Dehate about some time-sensitive business about a week ago and never got a response. I tried to call today and got an answering machine. Anyone seen Robert lately?
