    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...

    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.

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...

    Welcome to my ambitious build! A little backstory: My name is Caden, I'm 18 years old and this is my first year in HPR. I've recently completed my level 2 certification and ever since I've been anxious to move onto something bigger and better (I know I'm another hot shot young guy). Below are...
