Well, well... Its been a hot second (AKA over 6 months) since my last video, but its finally ready. I'm pleased to present my submission to Ortus City, a fully reusable spin launcher! The reason this took so long is that I went through several different failed designs that ultimately took a lot of time to develop. However, that time is not lost; I learned a ton from it and some of those failed designs show promise for future projects... So hopefully that means the next video will come out in a more reasonable timespan. This project was organized by Knight of Saint John. They contributed a huge amount of effort into organizing and building this city and it really shows. Check out their showcase video here! kzfaq.info/get/bejne/i9WJg6ti3uC3nYE.html

"Use these Mammoth engines as RCS thrusters" is a phrase I want to never hear again.

The whole "mammoth engines as rcs thruster" really puts the insane size of this thing in perspective

NASA administrator: "Why do we jettison the fairing and do stage separation so high up in space?" Engineer: "Reliability. At that height Florida is rendered at a significantly lower LOD, so it reduces lag, and without Atlantic wave physics we can easily delete the booster debris from the ocean" Administrator: "That makes sense"

Can we appreciate how this guy perfectly positioned and timed that spin launch so that the payload could intercept duna from minimus

I figure putting a huge spinning arm with a projectile attached exactly in line with the colony is the most optimal way of positioning it in case of a failure.

Hes in Spain without the a Very nice job on the sci-fi trebuchet, perfect cherry on top for this incredible outpost. I have absolutely no doubt that whatever upsilon comes up with next will be even more ambitious and awesome. keep up the good work homie

Normal people: 'I put this payload into orbit with a rocket!' Stratzenblitz: 'Haha, payload go YEET!'

This is just incredible, great work to everyone who participated in this project!

"Wow that's gonna a pain to disassemble, launch, land, and reassemble" I thought. But apparently there was another solution to that problem. Subscribe button smashed.

However much I am grateful for the time and effort everyone in the team put into this project, without you, neither Upsilon, nor Ortus City would have been possible in the first place. And on top of that, you've been able to push the limits of KSP yet again! All that while holding a stable job... if you can do this, then I guess I should give it a go as well. Being perhaps the only person who has had to record a lot of footage inside that lag-infested city, I've acquired new heights of respect for many of your previous projects. *cough* helicarrier *cough* You didn't compromise on getting the best shots, in spite of the strain this project puts on your sanity. Truly Marvelous! (oh and by the way, I take that comment about 'unruly dissenters' personally)

The good thing about the lag, is that you can never miss your ejection timing. You even probably can make yourself a cup of coffee while releasing, because of the immense lag due to the unclamping process. Genius.

I appreciate how this channel has slowly shifted slowly from building more and more impressive crafts to completely fucking over the physics engine

The insane engineering and calculations necessary to build the launcher...throws the payload the wrong way flinging it into interplanetary space, nice! Then uses it to throw a bunch of (flattened) minty ice cream. Genius

This launcher has an impressive amount of engineering to it. Well done stratz!

The amount of physics simulation mastery and just regular physics know-how that's gone into this project is just downright impressive

Well done to Stratzenblitz and everyone else who worked on this project! We really smashed a few colony records here and set new standards of cool! (Also as the designer of the spaceport, I hereby announce that the radar of the control tower can spin at 460 rotations per minute. Who in hell needs phased array radar again?)

THE UPSILON INTIATIVE IS STILL ACTIVE?!? EPIC that City looks Glorious btw, absolutely glorious, the builders who made those buildings are phonomenal artists. I lost it when I saw the fish tank That spin launcher is amazing too, it looks great, functions spectacularly and is awesomesauce

The Electric-To-Duna video is still your magnum opus, but this video is an elegant demonstration of your ability to inject magic into the science of the KSP world.

i love how the spin is in the same plane as the milky way, makes for a majestic orderly background

I love that old spinlaunch ion engine video to death, the music and cinematography were perfect. I am glad to see you revisiting the concept. Also, doesn't the game allow you to hotkey any engine as an RCS thruster with the robot parts expansion?

The Spinlaunch concept just made an impressive come back to the KSP universe, which it should have NEVER left.

the joker threatening space-gotham after he hacked the spin launcher

A magnificent build. Also I always love to see your elevator designs, each one is a little different and equally awesome.

This is what a master of a sandbox game looks like. It’s insane how much knowledge about the game you have. Mad respect

The stream for this was so much fun to watch!

Absolutely incredible work. You are definitely the most impressive KSP youtuber, always love when a new video comes out.

It's so cool, most people watching haven't even watched the hours long stream you did for just the launch and landing of this

This Guy came back for a Spin Launcher and just disappeared again.

Love this solution. My own Minmus fuel station to LKO route involved driving the payload as fast as possible along the flats until they become airborne before switching to conventional rockets. Only saved about 40 m/s Δv and was really finicky.

I've always fantasized of the concept of a centrifuge deployment system and you just made my day so much better

I discovered your channel recently and it has quickly become one of my favorites. I absolutely love your ideas, engineering, editing, and style. I am so excited for your next upload, as I know it will be fantastic. Keep up the good work!

Imagine having such intimate mastery of a game that you can do something like take B-reel and stage shots whilst still casually maintaining the orbital mechanics of rockets and landers. Props to Stratz for showing that it IS rocket science… and rocket science… at least in game… can be pretty easy with enough hours and practice 😎

I think using the word "engineering" instead of "building" is pretty accurate for this thing

Always a great pleasure to watch your videos and admire your amazing skills !

this is absolutely amazing well worth the 6 months of wait ly and hope u had a great xmas stratzen!

As I said on Knight's vid, It was an honor to work with you all. I hope to be able to do this again! ~Still Snosib- Still too lazy to switch accounts

I'm 1 minute into the video and I'm already convinced that you broke into several high security facilities to assemble the computer you're playing on

From all the ridiculous builds I seen in KSP over the last 10 years, this probably takes the cake, amazing! I love it.

Man, your videos are always so well done. Thanks for the awesome content.

im starting to believe stratzenblitz is obsessed with spinning catapults

Gonna Need to step up our game to reach this

Such an awesome looking addition to the city. Definitely the coolest thing there, plus it comes with real and useful application. Nice job!

The amount of planning, design, and time (lag) you all endure to put together such a GOAT of project is so well appreciated. Fantastic job on the video and much love to all the contributors 😃

WOOHOO! I started playing KSP with the intention of building infrastructure, my plans are well under way, and Minmus has proved to be an essential part of those plans. I love this video already and I've hardly started watching. :D Ortus City looks super-cool from above. I'm taking notes for my city plans. :D :o the gravity hab! socool! _notes down the mod name for rocket rcs_ i wondered if the 200m limit would play a role. i rewatched the dres canyon bridge video the other day to remind myself of it. haven't used it yet tho. interesting bearing! all this bearing stuff is still in the future for me. 5000 hours is not enough! haha! let me guess; the tanker's actual target is another planet, and it's going to get there with a kerbin gravity assist... aw, but that was just wishful thinking. :D oh duna, cool! got to keep those dissenters in line! XD great launcher, great city!

"In order to save fuel launching from the moon, we strapped 150ish saturn v rockets to a 38,000 ton tower and sent it to space" Also, spinlaunch is a real thing people are working on... just without the nearly 200 saturn v rockets.

You never fail to impress. This is awesome!

This is absolutely awesome! Dang!

He ditched us

Hey, I remember watching this stream! How possible is it to colonize (surface base + orbital station) the entire Kerbol system in one launch? Asking for a friend.

Hell yes, a new video! Every time you make one, it’s awesome

This is the coolest construction yet. Thanks for sharing!

It'd be awesome to adapt this to make a working skyhook (as seen in Kurtzgesat's video)

You think you could make a space elevator on Gilly using the base anchor thing?

YESS I'VE BEEN LOOKING FORWARD TO THIS SINCE THE LIVESTREAM

This is a certified "Yeet" technique of transporting cargo in space.

I want to see a scaled down version of this. Just so I could make my own mini outpost complete with smaller space yeeter trebuchet to deliver smaller payloads possible up to 50 tons.

I wanted to watch this but I forgot the name so I searched ‘big spin boi ksp’

Man that was epic. I love ksp so much.

god damn dude i cant stop watching this, something so satisfying about the spinlauncher going YEET

Mind blowing. Like every time you do something like this :D

Spin Launchers, so hot right now. Nice work!

Thank you for continuing to upload even if it's through long time gaps

Great video, such a cool idea!!

Incredible! I would never have the patience to stretch the limits of KSP to such an extend

The amount of dedication, the edition, no lag footage to us..... I hope you grew a lot more in here

Using Mammoths as RCS is something only Stratzenblitz would do

Loved this video. Great work!

New sub. I've watched KSP videos for years, but i feel like I've literally doscovered a new world of Kerbals.

The master is back at it again. Cant wait for the next crazy kerbal defying contraption!

This was somehow enjoyable to watch :D

Been waiting for one of these

This is proper kerbal engineering, I'm amazed by this!

Ahh still waiting for the next vid. Hope it is great like all the other ones.

Amazing, KSP master.

This man is underrated, i mean LOOK AT THESE!!

Best KSP video of 2021

In the end I low-key expected you to strap Jeb to the launcher with a seat, just to see how far you could throw him. Amazing work!

This has to be the coolest thing I've seen in KSP so far. And off I go to build a yeetinator of my own.

These guys are gonna do some wild stuff in KSP 2

This whole video is just... Geez. A lot of Gs

First video I've seen of yours. 5 minutes in and I love it!

this is truly remarkable

Glad to see the video after the livestream! Nice work on the video and the 37 Gs!

I didn't think it'd be possible to make something like this. Not even just the spinner but the city as a whole!

I'm speechless Very Nice! 👏👏👏👏

Your videos are always incredible

The legend returns!!!

Holy moly this is amazing

TCA is my favourite KSP mod. absolutely the GOAT.

imagining being in it made me motion sick. Nice video!

The long anticipated video is here!

This dude is insane. Subbed

You are truly the best ksp player I have ever witnessed.

"speaking of things you shouldn't do..." and the camera shot had me cracking up in anticipation. Good video.

This was incredible! Waow! 👁👄👁

Awesome design. Very well done.

All the creations in this base are amazing, man I love the KSP community so much, I wish I could contribute something

I love how he is making concessions to realism with the counterweight and overall spin launcher design, then uses THAT launch vehicle.

first time on this channel and im blown away by the production quality. Also my pc would melt if I tried to load that many structures next to each other on the minmus haha
