    Madcow AGM-33 Pike

    The AGM-33 Pike is one kit I've wanted for quite some time. And now, thanks to Papa Elf & my 2019 CIJ Secret Santa, I have one. Just to start things off, here is the OR file, updated with the measured weights for all the parts and a few things that I will be adding to the mix. More to come.

    Hey all, this will be my first post on TRF! I decided I wanted to go for my HPR certifications after building rockets with my school’s rocketry program this past semester. So, I bought myself a LOC 4” Black Brant X to certify L1 and L2 with. I figured going with the biggest kit I could find...

    Military Base Launches

    There is a particular Military Base (Bradshaw AAF) that I would like to approach to see about doing either an annual or semi-annual HPR Launch Day(s). The airspace is restricted (of course). I think (that's probably dangerous) that the FAA is not involved since it is an MOA. I need some guidance...

    Hard Hats in HPR

    BAR, only returned to rocketry about two years ago--and that was my first foray into HPR. Old enough (and hopefully wise enough) to be very serious about safety. Fortunate to be in a section that feels the same way. I'm curious if the NAR or TRA has ever considered adding a requirement for HPR...

    HPR Staging

    Newbie reaching out here on the subject of two stagers. I'm thinking of projects for Bama Blastoff this year and, having recently achieved my L1, though I'd try a more ambitious multistage rocket. I was thinking of using a LOC Goblin as the booster and a LOC Hi Tech H45 as the sustainer (they're...

    OpenRocket Streamer Issue

    I am currently in the middle of designing a rocket in OpenRocket that uses duel deployment. I was thinking about maybe using a streamer instead of a drogue chute. However, it seems to be acting weird when I put the streamer in. For example, if I don't put any recovery devices in the rocket at...
