Lesson learned… the focus ring is clockwise for closer, counterclockwise for further. Sorry for getting half the flight out of focus on the tracking cam.

You should release some of the music in your videos, it’s really cool!
Yes – it is all *very* interesting. Continue on this path. Naysayers usually do nothing but naysay (go figure).

Awesome video! Mimo systems is definitely a thing. One idea for the reaction wheel might be to leave spots for some heavier items you can put into the wheel like pieces of metal or nuts. Given that the frame is still in PLA it can create some nice moment of inertia.
Keep working on the wobbly oversteer, you’re an ace dude!
I’ll make that flywheel for you send me the file
4:45 yes.
Must have full control authority before I can sign off on the next launch schedule and L1 Dig day.
Things are getting serious now, i have followed you for some time now and im getting more and more exited for every video you upload.
Best of luck Joe! We are cheering for you!
I’m so in love with this!!!!!!
Hey, when are you going to space? srsly…..You feel like the next Elon Musk
You are inspirational! I’ve really enjoyed following you on this journey.
Yep, I made my decision. Of all my 200+ YOUTUBE subscriptions this is my current favorite YouTube channel.
I always thought it would be interesting to continuously optimize your gain values in a secondary feedback loop i.e. neural network optimization for gains
What an amazing flight!!
I would be interested in machining a reaction wheel for you if you have the cad files.
I love that launch pad… it even has launch clamps!
That looks like some nice valve hardware sittting there, AVA the next RCS system confirmed?
Yes! It’s interesting! I’m flying racing drones and am hobbyist so it’s all taken in with appreciation… by me at least
1:00 nice smiley face lol
One of the simplest yet most exciting videos you’ve done! Love it!!!
That 1st launch was an actual jaw dropping moment 😱
Great job……I felt like I was at Canaveral watching a real launch!!!!!! Minus the salt air !!!!
Congrats from France, your movies and this one too are so amazing! Very impressive! 🚀🚀
i was just starting to wonder when the next video would be released
Watch out for that reaction wheel. I’d tune it AFTER you get the I term in gimballing done. Looking at that footage makes me think that there’s a little of some kind of gyroscopic “coupling” between the two oscillations.
Epic, would appreciate videos of you doing the random things for this, maybe taking us a bit closer in to the process and making it more personal. Regardless, love the vids keep it up!
MIMO is totally a thing. Look up those fancy routers with multiple wifi aerials on.
I love how advanced the rockets you experiment with are!
Congratulation is Joe, I’m glad to see all your hard work paying off!
The interesting thing is that all of the “problems” that occur is probably 95% of the problems that “real” rockets have.
So there is very little difference in the complexity of what you are doing. Keep it up!
I love the thumbnail! Totally looks like a massive rocket!
The roll control just made me drool a little. Thats amazing!
Dude! That internal view with the TVC working and the “window” in the rocket body was super dope! Well done!
oof, right on the road
Reminds me of the time I had a rx failure in an rc heli and it just drilled straight into the only tiny patch of concrete within hundreds of feet … looked like it’d been through a wood chipper. Raised some real Ship of Theseus-type questions.
Have you ever considered flying a hybrid engine?
NO WAY HOMEMADE REACTION WHEELS!!
I dont Understand the design of the reaction wheel, also, will you have some trouble avoiding momentum saturation or the math works for even longer flights?
Absolutely fantastic, love the miniature tail service masts/hold down arms, keep up the great work.
Can confirm MIMO is a term used. I mostly hear it when dealing with wireless devices
I love that TVC camera angle. looking forward to the larger motors!
None pizza with left John. Nice
Yeah, its interesting Joe
Really enjoyed the quick recap with a lot of info. Have a great day!
I’m interested to know what simulation tools you use? I would also love to see a walkthrough of the model. Great content!
4:46 compared to you i am an idioT ,but i’m hanging on your every word, so YES….you were saying?
0:50 why is moving so muhc? nee new fins or something or somthing to avoid balancing the rocket with the fuel.
Lil guy is just swimmin his way to space like a lil fish and I support him
So cool! As a control engineer myself – I can verify MIMO is a thing! Also, since you are dealing with actuator delay, you might be able to incorporate the delay into your state space observer (if you have one), and by that make the control loop stable, because the control loop is aware of the delay. If you decide to go that way, look into delay handling with Observer/Kalman filtering, or even Smith predictors. Looking forward to seeing more state-space rocket control!
Damn joe really out here using aerotech motors smhing my head.
7:35 yes finally
*Department of Homeland Security has entered the chat*
I absolutely love the interior camera showing the motor gimbaling.
The green bps sign in the background looks sick
Yes it’s interesting, keep going.
Wow joe has really has gone revolutionary!
4:45 Yes! I want to hear more about PIDs
Roll control is amazing. I wondered how to do it, I thought maybe by movable fins. Now I know better. And it looks like it worked pretty well. 👍 Great job.
This is so cool. I love moving the tech level of model rockets from “gunpowder and cardboard” to some real GNC and reaction wheels. Thanks for moving the hobby forward Joe!
2:33 It is now!
4:45 Yes, it is fascinating.
Really great video! Loved it, seeing sprite paying off. Have you done a video on the simulation software you’re using it sounds interesting.
Taking the time to tie what you’re doing all together by explaning your long term goals in a video, will drag more people in… people love anticipation.
4:44 Absobloodylutely!!!!!!!!!
I’ve been a rocket nut since my first guyfawks as a kid but I was never dedicated enough to my studies to make a career out of rockets!
One day I’ll build a rocket motor but I don’t think I’ll get to the point where I’ll do what you are doing!
Thanks so much for sharing your journey! You are travelling a path I would have loved to have taken!
He lost me at “linear quadratic regulator” hahah
Nice launch!!!! Love the TVC!
“Back to rockets”
WOOT!
6:22 I learned that the hard way too… Make it simple… It will became difficult on its own
This is very interesting, and I love that you have a reaction wheel. Also, you’re making me feel better about my MFA in dance and inspiring me to up my game.
The test isn’t that hard
The test: him explaining
When he said “arrow tech”, the subtitles read “error tech”
So excited for 1 kilometer flights!! Also great test flight and lots learned from it.
4:45 It is very interesting! Your entire audience believes that. We wouldn’t be here if we didn’t think it was interesting. Keep up the good work!
I’ve been waiting for this test flight for awhile. And, yeah, whole lot of oscillation and overcorrection. Still, looks freaking great, Joe.
1:30 shit… That’s young elon! You freaked me out 😂
Hurwitz and Niquist would not like this video at all.
(Good job. I’m looking forward to the second test flight!)
Awesome camera angle of the tvc mount
“it’s youtube man, I’ll do what ever I want” I love it, congrats on the successful test flight!
2018: We’re gonna land this rocket
2020: WE’RE GOIN TO ORBIT
Yes! Yes, that is interesting, and I love it! Congratulations to this launch – if you can see a launch like that and dissect things that are wrong, you are in a good place
Once you have boosters, you can make the reaction wheel bigger and simulate gravity for your little space-cowboy
Love the smiley face on the back of the motor
Me: *High Pitch Squealing* “ITS FINALLY HAPPENING!!!!!!!!”
3:04
i’m just here for the carbonated milk, and dancing…
Question: what’s your ultimate goal about your rockets? Do you have an ultimate altitude that you wanna reach?
pizza john!
The long wait is over!!!!!!!!!!
“It’s youtube, maaaan, I’ll do what I want”
Did people actually cry about rockets not being launched? I honestly didn’t even realize you hadn’t launched one in a while. I quite enjoyed the test rig!!
I cant wait till Im done with this ME undergrad in May so I can just sit on the couch and go through your entire library of videos of MATLAB, simulink, data processing, programming, modeling, PCB design, ect ect.
For now, I only have time to watch your awesome launch videos.
Just pulled my 3rd all-nighter trying to keep up with assignments…
MIMO is a real abbreviation!!! We stand by it!!!!! and I’ve heard people with PhDs in control say it! RISE UP MIMO GANG
Also I don’t think people appreciate the leap it is to go from PID to state space— like that is a non trivial jump to make so nice job!
3:06 like drinking carbonized milk?
The interior view is so cool!
This is all interesting. I want more please.
4:45 i might not know what the heck you’re actually talking about, but that doesn’t mean it’s not interesting.
* volume warning*
Me: *wearing headphones* *blast off* “Uh why are my ears rings?”
I still can’t comprehend how the hell you do all this on your own, you have my eternal respect and admiration my man
1:28 literally return to launch site
4:45 yes.. definitely!!
2:33 Yup, currently taking a multivariable controls course and we definitely refer to them as “mimo” systems
I feel like I attended a technical debriefing meeting. This just BECAME a job!
Yikes! Right on the hairy edge of stability with that thrust vectoring.
Woah that inside view of the gimbal is amazing
Heck yes it’s interesting and viewers are retained as heck if they’re like me
