What diameter rockets and motors do you prefer or fly most often? Choose what comes closest from the available choices. Select all that apply. Feel free to explain and add other preferences (e.g., cardboard vs fiberglass, DMS vs RMS, single vs dual deploy, etc) in your post.

The purpose that I am making this post is to have a discussion about all things parachutes and recovery. Although I do have a few particular questions and want to hear others opinions, I want there to be a place where alot of this information can be found in one spot. Im sure there are other...

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 may be explained elsewhere, but I'm having a hard time finding reliable information about taking the NAR Level 2 exam. I received my Level 1 in March and decided it was time to go for my Level 2. I have the rocket, motor, and a launch date picked out. The only thing left is the...

Hello all, here is my plan for my L3. I have a limited time to build this as I have a specific date I need to launch by. I ordered all the components today, I also have a Loki M2550 on order for the flight. The launch will be the first weekend of June, so I will need to work quickly but...

Hey folks! l am a student freshman level at university. l am planning to build HPR and have a problem. l want to use Dacron polyester material for my parachute. l am not sure whether Cd is correct on openrocket software or not. As Nasa resources, ıt would be 1.75. But as openrocket software ...

Hey guys has anyone used a Telemetrum for single deploy before? Like deploy main at apogee and thats it? And also if a 28 inch parachute is deployed as a parachute at like 10000ft and I am prepared to walk for however long it takes could I recover it? Like with GPS guidance from the telemetrum...

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...

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...

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...

Hello! The other day I posted on here about an issue with my Hyperloc835. This issue has been fixed, thanks everyone that helped (and thank you, Loc Precision). I now have another question. I'm considering changing how my dual deployment is done. The instructions call for the drogue chute to go...

Falcon Rocketry is having a grand opening sale now that all products are in stock! To celebrate and mark the beginning of our journey providing high quality fiberglass rocket kits, we decided reduce prices on all items by 15%! This sale lasts from November 15-22 (Thanksgiving Day) or until...

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...

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...
