    Build Thread: 38mm Min Diameter Fiberglass Estes Vapor, "City Pop"

    Back Story: Aesthetic Rockets and Drag Separations I've been enamored with Estes' Vapor rocket since I first saw it mentioned. It's over a meter tall, slender, and has those photogenic, long, triangular fins. The problem, for a long while, was that it was a Hobby Lobby exclusive, and there's...

    Diameter difference between Body Tube ID and MMT OD

    Hello fellow rocketeers, hope you are doing well. As I kept designing my future rocket, one doubt came into my mind when looking at my BT and MMT. First of all, my BT is 1,968" OD and 1,85" ID; my MMT is 1,574" OD and 1,496" (38mm) ID. The thing is, there is only left 1 3/8 or 1,377" (3,5 mm)...

    Sold 38mm Hardware

    I've rediscovered my hardware but have been out of rocketry for a long time. It's all Dr. Rocket it seems and save for a new 98mm threaded Slimline retainer. Some of the cases have never been used; others no more than twice. I'm not sure which is which with regards to that. Prices don't include...

    Loc Terrier Sandhawk build thread

    There seems to be a fair number of people building the Loc Terrier Sandhawk right now so I decided to throw my build on here. I'm sure plan will evolve over the course of the build, but my two main goals for this build are focused on camera placement. I want one internal Mobius in the Sandhawk...

    Build Thread: Mega Der Red Max, 38mm: New Clone Kit

    Wanted to post a build thread on Toby's (Big_Red_Daddy on the forum) cloned Mega Der Red max kits. He's doing them in both 29mm and 38mm flavors and since I already have the Estes one with the 29mm, I got this one with the 38mm. (more fun right!?) I also got the optional nosecone bulkplate for...

    Streamer Recovery for 38mm Minimum Diameter

    After lots of test fittings, and experimentation I've decided that I'm simply not comfortable with using the JLCR in my 38mm minimum diameter project. Going to go with apogee deployment and a streamer instead to try to bring the rocket down close. The foundation for the build will be a Wildman...

    JLCR in 38mm Rockets

    I'm working on a 38mm minimum diameter rocket to meet some very specific objectives. These include breaking mach 1, altitude exceeding one mile, and transmitting sensor data via telemetry back to the ground during flight. Have a 38mm carbon fiber airframe ready to go, along with one of the new...
