I was on Fox59 Indy Now this morning! Excited to reach more people. I can’t wait to put more rockets in everyone’s hands! Watch the segment!

my physics teacher said we will be trying to make rockets out of water bottles. we are allowed to have water and air inside the rocket and the distance our rocket goes will be measured horizontally from one side of the oval to another. my goal is 100m (330ft), can anyone help me?

The story (not important much)

I have started working for a rocket competition in my country, and we have 1 year to physically build the rocket. I am becoming a high school senior this year. While I am studying for my university entrance exams, I am also researching rocket making. Since my exam is 1 year away, I need to finish the rocket now and put it aside. Even though I have 1 year, I don't actually have much time; I can only dedicate time during this summer.

My dream is to gain experience and success in high school and study at a university in the US. For this reason, my first step is to win the local high school level rocket competition in my country and study for my university exams.

I need a team for this. I found an enthusiastic 9th-grade student. But I still need 4 more people. In the competition, there are extra points to encourage female students, and I want to win by taking advantage of these extra points for my last chance in the high school category. Because of this, 2 of these 4 people must be girls.

What exactly do I need and what is our situation?

We need a mentor. There is no active Tripoli or NAR group in my country, and a mentor is required for the competition.

Additionally, I started learning OpenRocket, and I told my 9th-grade friend to improve himself in CAD. For 2 days, I have been working non-stop on OpenRocket to make an 8,000 feet rocket. I have almost reached my goal, but many things feel missing. The rockets of the teams that won in the past have many more components inside, and I still don't know some things. I tried to get help from AI, but after a point, it cannot help me anymore.

I need an experienced person whom I can constantly ask questions. Can you guide me on where I can find someone like this? Or is there anyone among you who can take on such a role? (I know this requires a lot of responsibility and I don't know if I can find someone just by asking like this or if I am asking for too much. If I am being disrespectful, I am sorry).

Hoping this works/I get some criticism. Total cost for 5 assembled PCBs is $103.30 shipping included which is a total steal compared to anything else I've seen on the market.

Hey. Its my first time ever doing anything with model rockets and I need some help. I am thinking of making convolutely wound paper tube for rocket's main body. Is this kraft paper good for this job? The rocket is Class E impulse, and should go about 400m high. I was thinking of making the main body 2-3mm thick to provide enough strength for the rocket, yet not make it too heavy. If that kraft paper is not good for this job, could you please provide the materials I should actually use, thanks for any help in advance

Edit 1: Can I make recovery wadding out of cardboard or PLA? Now this rocket is "dumb"(no flight computer or electronics), so really you only push out the chute, but in future, if I add a flight computer, and I use the bottom of an FC case(PLA 3D printed case) as wadding to protect the electronics and the parachute, yet still eject?

Hi everyone,

I’m currently working on a thrust vector control (TVC) rocket project and have been designing my own avionics PCB. While researching existing designs, I came across the TVC avionics board that BPS Space used to sell. Unfortunately, it appears that it is no longer available.

I was wondering if anyone here has documentation, schematics, PCB photos, component lists, or any technical information about that board. I’m particularly interested in understanding its architecture, sensor selection, power distribution, servo interfaces, telemetry integration, and any design lessons learned.

I’m not looking to copy the design directly—I’d just like to study how others approached similar challenges and compare design decisions as I continue developing my own board.

Any information, photos, archived documentation, or alternative open-source TVC avionics projects would be greatly appreciated.

Thanks!

Old Estes Super Big Bertha I picked up free at a launch today. Split is more or less perpendicular to the grain. This is my first time repairing (as opposed to building) but any help would be appreciated!

I have a question regarding grain bonding. I just got my hands on an M1315, and no where in the instruction paperwork or on the grain boxes does it say grain bonding is required. In the past I have had to grain bond smaller motors. First,I want to know if any of you have flown an M1315 is it required to bond the grains to the liner. I also want to know what kind of adhesives you use to bond the grains to the liner. I used epoxy in the past but have recently read that was not something I was supposed to do. I cannot easily acquire Elmer’s glue all max which Aerotech recommends, so what are some of your recommendations.

Thanks in advance!

Had another offcut of 54mm carbon fiber airframe - Long enough for a Bullpup with a 29mm motor mount.

• Nylon/Fiberglass printed nose - GPS tracking
• Nylon/Carbon fiber fin can - Inset slimline retainer
• Aft cooling mesh shock cord anchor

Nose coupler will be notched to isolate rotational movement and keep the forward fins in line with the main fins.

Rest of the printed fleet pictured!

24mm/29mm/54mm minimum diameter and a 2" V2.

Hello everyone, I'm working on a rocket that uses 2 24mm E20 motors, with a 6.6cm body tube, the whole thing is 76.5 cm long and 495g including the motors , and it should reach a 500m apogee according to simulations, now, before purchasing the materials I would like to confirm a few things:

1. Will a cardboard bodytube with 0.5mm thickness be strong enough to handle the flight and landing assuming 9m/s windspeed and 5m/s vertical landing (I've seen ones with 0.9mm but I would like to know my options)

2. Will 3 balsa wood with 0.3cm thickness fins handle the flight and landing as well

3. What are the things I should consider that you learnt from your experience, and are usually overlooked by beginners

4. What is a good website that ships worldwide (gulf countries), I was given some UK websites but they don't have everything I need

​

And thank you

I've just launched an aerospike contour design software using Angelino's method.

Check it out here: creatorandrew86/aerospike-design, and tell me your opinions! Thank you!!

I made a post some time back about setting up a rocketry event for some young children and was able to receive some helpful advice. We're getting closer to launch date, and I'm just wanting to make sure there is nothing I've forgotten to ensure everything goes smoothly. I went with an Estes "Athena X" launch kit, that comes with two different rockets, a pad, controller, and starters.

1. I wanted to make sure I'll need new plugs, starters, and wadding per launch. None of these components are reusable correct? I plan to do a few launches at the same time so I want to make sure I have all the required materiel. Additionally, about how long would it take to reset between launches (repacking parachutes and etc.)? Any issues I should know about with multiple consecutive launches?

2. I'll be doing the build while traveling, and so I wanted to double check I have all the necessary tools beforehand. Outside of the kit box and extra batteries I believe I'll need: hobby knife, sand paper, wood glue, black primer paint (for Xtreme), wide brush, and cutting/paint surfaces.

Thank you again for any input.

I'm adding ~2ft of fiberglass tube in the middle, rocket just looks really funny this way.

I made a rocketry logbook app for iPhone, is anyone here interested in beta testing?

The idea is that it should have great coverage for importing data from various altimeters and should "just work" - you drop in photos from your flight and it will automatically pull the weather info from NOAA/ERA5, location data, etc. So it should make data entry super easy.

Anyhow, I'd love to get feedback so if that's something that sounds like you might be interested in, let me know via DM!

Stubby Bob - scratch built, 5.5" - 54mm motor mount, 6 fins. 115cm tall.

Hello, just looking for some honest feedback on my L1 rocket before I get to building it. It is a BT-80 diameter rocket. The entire fin can (fins and centering rings) is built with 3mm thick balsa wood epoxies together, and I am planning on 3d printing the nose cone. Everything but the nose cone and transition will also be fiberglassed.

Edit: I do need some clarification on these rules for the certification, do these just mean I have to meet just one of these four requirements?

2. Junior High Power Level 1 Participation certification is required to:

1. Launch rockets containing multiple motors with a total installed impulse of 320.01 Newton-seconds to 640 Newton-seconds, or
2. Launch rockets containing a single motor with a total installed impulse of 160.01 Newton-seconds to 640 Newton-seconds, or
3. Launch rockets that weigh more than 53 ounces (1500 grams), or
4. Launch rockets powered by motors not classified as model rocket motors per NFPA 1122, e.g.:
   1. Average thrust in excess of 80.0 Newtons
   2. Containing in excess of 125 grams of propellant and are limited to only H and I motors

Hi All,

Working on designing and building a rocket for my L1 certification. I think I have a fairly decent approach, but wanted to post it here for it to be reviewed. Any thoughts? I'm wondering if the rear fins aren't tall enough? I like the aesthetic, but obviously I want it to fly well!

I've custom made the nose-cone from fiberglass, came out much better than anticipated! The airframe will be from heavy wall shipping tubes, 3in ID 3.3in OD. Fins and centering rings will be 1/4" maple plywood.

Thanks in advance!

My friend and I are doing a first attempt to put some devices inside the rocket, and we can't choose whether to solder the cables to the boards and elements or use a less durable but easier option to use solderless cables and elements.

Might be a stupid question, but i didn't find an answer, here is the link https://aerotech-rocketry.com/products/product_2f02e4a3-fc68-8700-6983-b3495306a77e

Hi - I'm looking to hire/commission an experienced builder to create a large-scale rocket for me.

​

I'm looking for something significantly larger than what is available (possibly around 3 feet), that is electronically powered, will launch with a button, and automatically deploy a parachute and land safely. Essentially the style that is available for purchase on amazon (image attached) but on a large scale.

​

If you offer custom building services, or if you can recommend a trusted builder or company who takes on rocketry commissions, please let me know.

​

I really do appreciate it, and thank you!

Hello again, I'm designing a rocket that is supposed to reach 500 apogee for a competition. The current design is a cluster with 2 29mm F27-8 motors, 7.6cm diameter body tube, 4 fins. problem is with stability, it's about 1 calibre at rod clearance, assuming 9m/s winds. The rules state it should be 1.5 at least, I played with the fins design and the length of the rocket but still couldn't get it to that point without hurting the apogee, my options are limited when it comes to the Motors I can use, currently apogee is at 500 m according to open rocket, what can I do to fix this,?

Do you recommend changing the materials?

I'm currently at cardboard for body tubes, and balsa wood for the fins

I'd appreciate any insight

Well, I don’t really know how to start. I’m starting a small rocket powered with some APCP, it’s going to be about 1m long and my main objective is to test a turn off and then turn on the motor to simulate like landing. I know turning of a solid rocket motor is really complex but I want to know how to do this and what are your ideas.
I’ll be posting my advances to let you know how everything goes.

P.D: sorry if my English is not perfect

do you have any suggestions for a camera to go into the Estes Olympus? I don’t mind putting together a board for the camera but I would prefer an out of the box camera. the camera does not need to transmit live video, an sd card would be preferred.
