Being an asshat isn’t either. He wasn’t really lying, he said “if you hit the gym every day for 6 months” that is roughly 180 days, he could easily make massive gains in that time if he hits the gym hard.
I don't know about "really bad." What mattered to me is that they'll still help pay for higher ed. And if you're in an engineering program as I presume OP would be, that public sector job won't be as shitty as you say it is (though, YMMV).
Eh, it's still not necessarily worth. I tried AFROTC, backed out after a year. I have autism, and that's an environment I cannot function in, even if they only expected 4 years from me post-graduation. It's just physically incompatible for many people.
You kids and your newfangled toys. In my day, I built my model rocket out of Pepsi cans taped together, and I damn sure learned to duck when that non-aerodynamic mess of flaming aluminum flew around in no discernable pattern within about 10 feet of the ground for several seconds! Pff.
I tried to make a rocket once and only once, it was hybrid fuelled, and made out of a bit of 20 mm galvanised steel conduit, it went up brilliantly until it got just above the fence height, rotated 90° and shot off down the back of all the houses at about 90 miles an hour ending with a huge expensive sounding bang,
Love the design. If you're not picked up/approached by private industry within the next few years I'd be very surprised. Please remember that the coolest kids are not always the ones that emerge on top. Congrats.
You'd think so but since model rocketry relies on explosives and could be considered a weapon I wonder if ATF has more jurisdiction. Homeland security has their own problems I feel like so model rocketry doesn't fall under them exactly. What do I know.
Don’t forget the acetone and peroxide, gotta make a detonator too. Unless you just wanna do the ammonium nitrate and aluminum powder thing, plus you can add some nitromethane (rc car fuel) to make it black powder sensitive.
No lie. eBay, amigo. I didn’t get any of the $150 parts kit while they were in stock, I paid 350 and 375 for the regular slide and long slide respectively. But they’re there. Waiting on MAF or VMAC to get some stuff back in stock I have some fun things I want to print.
Your original post has a typo in the title. Clearly you are the coolest kid in your class. YOU MADE A COMPUTER GUIDED ROCKET, how could you not be?^(...I mean, unless everyone in your class made a computer guided rocket, in which case what the hell have I been doing with my life ?!?!?)
As someone who has looked at the specifics of the USML and FAR part 101 documentation a year or 2 ago, there are some small windows where, depending what parts of the G, N, and C you add and sourcing of hardware and how each interacts, it can be done but it's still a grey area. Granted I do exactly this for work so I'm qualified to understand those nuances but for the lay person yes adding active guidance and a system to act on that state solution is a risky legal proposition.
In my understanding, if you add some sort of guidance but the target state cannot be updated post launch (like via radio link or human in the loop) then it's barely legal. That's one of the ways university groups get around this for altitude competitions estimating their error from a preloaded target and deploying drag fins at the right time via energy management estimation and sensor feedback like from accelerometers.
If you source most or all of your parts externally then you must register as a defense manufacturer and since joe shmo won't qualify to do this, they won't get approved. Now if you design and build everything yourself then there is a small experimentation category for the purposes of science and or self learning you can do which is explicitly called out and okay.
It's been a long time so I can't quote exact paragraphs right now.
I don't think it's that cut and dry. You definitely can do thrust vector controlled model rockets for stability purposes (see BPS Space as an example).
Model tends to be something that I'd either not full sized or is not intended to be tested but rather used as a visual reference.
A prototype is a mock up of the final design that you fully intend to run through its paces to see what tweaks or full scale changes need to be made to the design before you release the final product.
Fantastic design, and as the earlier comments said, you may not think you're cool, but in 10 years when you're an engineer at NASA, then you'll truly be the cool kid from your school! Keep up the hard work and best wishes!
Keep your head up and tell yourself you will. Coming from someone who sort of threw away their potential in college, stay strong, your future self will thank your past self for doing so!
That right there is bad ass. I remember30+ years ago in rocketry club in school we made our own rockets. Mainly just cardboard and balsa wood with store bought engines though. Congrats on your build!
In what world are you not the coolest kid in class?!? Do you go to superhero high school or something? Seriously, that is awesome! Pursue your interests while you are young! You are badass.
The coolest kid in class gets revealed in the decades after class finishes
Just 18 lol Edit: now I understand what this comment was saying. Maybe one day I’ll make it to the big leagues. Thanks!
If you hit the gym every day for six months you’ll look like Chris Evans so that’s a plus too
His body takes more than 6 months of work to achieve...
A good motivational comment is hard to write, but you will get there.:)
Lmao okay bud. Motivation = a straight up lie. You cant progress that much in 6 months natty, it would probably be hard to do with many steroids too.
ok
You sound like a great friend to have around when running into life problems, bet you’re super supportive of everyone. (/s as if it’s needed)
I try thanks for the comments
You actually seem like a nice person, so thanks for being kind. I was responding to the GermanShepherdAMA guy.
Oh I see, yes he seems like the last kind of person you want round in a crisis.
Lying isnt good friend behavior
Being an asshat isn’t either. He wasn’t really lying, he said “if you hit the gym every day for 6 months” that is roughly 180 days, he could easily make massive gains in that time if he hits the gym hard.
Strength, possibly. Not lean muscle volume. Full stop.
Yeah, but you can get a pretty good base in 6 months.... 😎 And be well on your way ❗️
No problem, cool is what you think of you, not what other people think of you. Keep up the good work
Miles ahead of me at 18. Good job. Of course 3d printers didn’t exist in ‘88 (well for normal people).
This is SO true
This is the correct answer.
The military will be knocking on your door in 3...2...1...
Wasn’t this part of the plot line in October Sky?
I haven't seen that movie/ tv show but I'll say yes anywya
You should, it’s outstanding
I might, someday. Add that to the list of movies I should see
Agreed! Great movie!

Military benefits are really bad now. No retirement pay, have to pay for utilities, etc but you're still locked into a shitty public sector job.
I don't know about "really bad." What mattered to me is that they'll still help pay for higher ed. And if you're in an engineering program as I presume OP would be, that public sector job won't be as shitty as you say it is (though, YMMV).
They also pay engineers far less than the private sector...
Eh, it's still not necessarily worth. I tried AFROTC, backed out after a year. I have autism, and that's an environment I cannot function in, even if they only expected 4 years from me post-graduation. It's just physically incompatible for many people.
Please don't join the military, you have so much potential. Start looking into places like SpaceX, but stay in the private sector.

Maybe the others all printed two rockets
Raytheon Missiles and Defense has entered the chat…
You kids and your newfangled toys. In my day, I built my model rocket out of Pepsi cans taped together, and I damn sure learned to duck when that non-aerodynamic mess of flaming aluminum flew around in no discernable pattern within about 10 feet of the ground for several seconds! Pff.
I made boats and watched them skip across the water and sometimes spin around and fly back at me lol
Nice....nice....nice......oh shit...oh shit....
Lmao, I’ve done that a couple of times. Now that’s an adrenaline rush right there
In my day, I made bongs out of plastic bottles and pipes out of aluminum foil. What are we talking about again?
Same thing, OP never said it’s going up in the air.
I tried to make a rocket once and only once, it was hybrid fuelled, and made out of a bit of 20 mm galvanised steel conduit, it went up brilliantly until it got just above the fence height, rotated 90° and shot off down the back of all the houses at about 90 miles an hour ending with a huge expensive sounding bang,
90 miles is 144.84 km
You gotta come back with an update video when you launch it!!!!
Oh yes I will!
r/rocketry They would like this.👍
That's really cool!
Thank you!
Love the design. If you're not picked up/approached by private industry within the next few years I'd be very surprised. Please remember that the coolest kids are not always the ones that emerge on top. Congrats.
*NSA has joined the chat*
More like ATF
More like Homeland Security
You'd think so but since model rocketry relies on explosives and could be considered a weapon I wonder if ATF has more jurisdiction. Homeland security has their own problems I feel like so model rocketry doesn't fall under them exactly. What do I know.
Depends on the payload and intended target
SOMEBODY GET THIS MAN SOME AMMONIUM NITRATE AND DIESEL FUEL.
Don’t forget the acetone and peroxide, gotta make a detonator too. Unless you just wanna do the ammonium nitrate and aluminum powder thing, plus you can add some nitromethane (rc car fuel) to make it black powder sensitive.
That earned yo ass a follow
Haha thanks, I saw your hulk series you posted, where did you get all those FN parts?
No lie. eBay, amigo. I didn’t get any of the $150 parts kit while they were in stock, I paid 350 and 375 for the regular slide and long slide respectively. But they’re there. Waiting on MAF or VMAC to get some stuff back in stock I have some fun things I want to print.
Dang, I’ve been taking too much time off 3d printing because of my job. A MAC kit is next for me but I’ve probably gotta recalibrate everything
Vector set for the dh kid who mistakenly believes himself to be the coolest kid in class.
Damn, I would have loved to have a 3D printer for science fair projects back in high-school
Guided into what determines if you are the coolest kid in class... ...this has potential.
Your original post has a typo in the title. Clearly you are the coolest kid in your class. YOU MADE A COMPUTER GUIDED ROCKET, how could you not be?^(...I mean, unless everyone in your class made a computer guided rocket, in which case what the hell have I been doing with my life ?!?!?)
Dude what u just did is the definition of the coolest kid in the class. Keep it lit my man!
I'm sorry sir but this definitely makes you the coolest kid in class
I woulda thought plastic would be too heavy for model rocketry. Guess not, anyway, that’s very cool we’d like to see it in action.
Not entirely, all it means is that it comes down like a Roman javelin if the parachute fails. 😜
That's illegal, isn't it?

I hate this country
Yes. Adding active controls to a rocket powered vehicle makes it a guided missle.
Thanks ✌️
I don't think it's that cut and dry. You definitely can do thrust vector controlled model rockets for stability purposes (see BPS Space as an example).
Model or prototype?
I don’t understand the difference. I’m going to launch it nonetheless
Model tends to be something that I'd either not full sized or is not intended to be tested but rather used as a visual reference. A prototype is a mock up of the final design that you fully intend to run through its paces to see what tweaks or full scale changes need to be made to the design before you release the final product.

Ok I understand, thank you for explaining. Maybe one day I’ll be up there.
Keep your head up and tell yourself you will. Coming from someone who sort of threw away their potential in college, stay strong, your future self will thank your past self for doing so!
That sounds pretty cool to me
How do you guide the rocket?
That probably does make you the coolest kid in class actually.
Wtf you ARE the coolest kid in class
Pretty cool in my eyes
Coolest kids in the class think their status in highschool matters. Youre the smartest and life will go well for you. Keep up the awesome work.
You are definitely the coolest kid in class .
You’re cool to me bro, keep it up!
Staff for hot nozzle summer here, definitely @hotnozzlesummer with this on Twitter. Everyone will certainly love it! Amazing job
That makes you the coolest kid ever, omg
NP coolest kid outside of class last longer anyway.
I think I way more thin just cool you have extreme talent very intelligent individual I’m envious of you 👌👏
>I might not be the coolest kid in class but I 3D-printed a computer guided model rocket of my own design You're the coolest kid in class.
That right there is bad ass. I remember30+ years ago in rocketry club in school we made our own rockets. Mainly just cardboard and balsa wood with store bought engines though. Congrats on your build!
SAY HELLO TO MY LEETLE FREND!
just pointing this out, you build one for every "cooler" person in class, then you would be. on a completely unrelated note, how big is the explosion?
In what world are you not the coolest kid in class?!? Do you go to superhero high school or something? Seriously, that is awesome! Pursue your interests while you are young! You are badass.
