Breaking Kerbal Space Program by Only Using Monopropellant

[@ReidCaptain]

I still want to try using the mining equipment in the future. I was thinking of doing a planet hopping mission, but does anyone have another good idea?

[@robotrick6891]

Maybe capturing an asteroid? I don't know if this is possible, but you could refill your fuel by mining the asteroid so it could be possible

[@SephirothRyu]

Redirect asteroids to crash them onto the space center. Yes, ONTO.

[@jakemckee2005]

I recommend making fatter rockets out of bigger parts, and making much stubbier landers. Big tall landers like these are much harder to land. Also, when returning to Kerbin, the easiest way to land is to just send down a capsule with a parachute and heat shield into the water

[@snowboyz0825]

Yo you got this idea from me! Commented on the solid rocket booster vid. I'm not mad, honestly just happy

Engineering Advice: - You should put more effort on minimizing weight. The rocket equation means that removing 1 kg of dry mass is *much* more effective than adding 1 kg of fuel. For example, the Mk I cockpit is one of the heaviest single-kerbal command modules in the game. The Mk I Lander Can is nearly half the mass - You can improve FPS and decrease flop by using larger fuel tanks. As you found, the tanks all have roughly the same mass ratio, so fewer, larger tanks will be more rigid while holding the same fuel and being the same mass. - As you found out, it's not a good idea to add a payload right at the start. If you aren't doing careful mathematics, you can't know how much your rocket will be able to lift before you build it. - Make sure you're using small, lightweight upper stages. Up until the final design, your final stages were missing out on a lot of delta-v because of how much extra mass in engines and empty tanks they were carrying.

[@paranaenselol]

He should also try making a plane that sends the payload, there are the space shuttle like monoprop tank and the jet monoprop tank

[@theencolony5595]

Here's a couple tips: if you alt-click a stack, it will copy the parts If you open the actuation toggles on the RCS parts, you can enable "control by throttle", allowing them to be used like regular engines

[@charlesgarlets5362]

Hey RC, I love the channel, and I have some tips for you about KSP. 1. In the editor, you can press the 3 buttons above the symmetry to show center of mass, aerodynamics, and thrust 2. In flight, there are a few buttons on the bottom left. the bottom purple one is very useful for showing flight info like apoapsis, periapsis, and when you will hit them. 3. You can enable/disable fuel crossfeed throughout decouplers when you right click on them (to prevent fuel going though to different stages) 4. In the editor, there are 5 blue buttons at the top. The 2nd one allows you to make button presses or actions (like pressing numbers on keyboard) that can do actions, like toggle an engine or extend solar panels I hope this can be useful.

[@chri-k]

5. The CTRL-Z copy method is unfavorable, undoing is very unstable

I'm speechless. While doing almost everything wrong, you still manage to achieve quite challenging goals in this game! From the building to the staging, everything is insane! This game was meant for that, and you've earned my subscription. You're joining Stratz, Matt, Scott and associates. You're like the unprofessional version of them, I feel like watching a hamster on cocaine and I love it! Keep doing what you do! (All is meant as a compliment, by the way ;) )

[@Denamic]

It's actually more efficient to have 1 double size fuel tank than 2 smaller ones, even of the amount of fuel is the same, as joints can be a bit wibbly wobbly and end up magicking energy away into the nether instead of making you go more up. Especially if it's a load bearing joint.

[@thirsty_yt6481]

This dude is literally the definition of "more is better"

[@AmryL]

On top of all the other tips that people have given you: if you click on the 'Total delta-V' number at the bottom of the stage bar (bottom right in the VAB, bottom left just above the attitude gauges while in flight), the stage bar expands and gives you useful stats fot that stage, like Thust-to-weight, burntime at max throttle and delta-V. On top of that, in the VAB the DELTA-V button in the app-bar allows you to set the parameters for those calculations. You can check quickly your T2W of the final stage on say Minmus, which is in low gravity and in vacuum.

[@ryanspence5831]

4:41 you’re wrong, it calculates the mass of physicsless parts by adding it to the parent part’s mass

[@chri-k]

Which can sometimes have very unforeseen consequences on weird rocked designs ( like these “only X” rockets )

[@serendipity-tilde]

Protip: You can hold alt while dragging them to duplicate :D You can also enable "control by throttle" on the RCS, which basically makes them an engine.

Control Z copying causes crashes because assets get stored in ram and never unload, so the more you copy and use copied parts the more likely it is to spill over and muck everything up Edit: oh, this is conjecture, by the way. I just know others have that issue.

[@ajdinhalilcevic6270]

Considering the means of propulsion, this is just a giant bottle rocket.

[@safehavenonice6431]

In case no one else let you know: There's an option you can use in the *decouplers* to disable crossflow between stages. Good for use in disposable booster stages. Edit: A wise Scot also told me that the max G's you hit in atmosphere ideally shouldn't top 2 or 3, otherwise you're just wasting thrust pushing around air.

[@HappyBeezerStudios]

yup, when any other part of the rocket besides the engine starts to glow red, you're going too fast.

[@hinglemcgringleberry]

[@RagerBlazer1]

You know that when Reid Captain uploads a video its already chaotic...

[@asparagusstaging430]

You can see the thrust to weight ratio in the editor.

[@eekee6034]

14:16 Pogo spaghetti! :D Rather more intellectually, you can look at TWR -- thrust to weight ratio -- to see how it'll take off. Click a stage thingy (with the orange top bar) for extra info. One of the 'apps' is a big-ish panel which configures which data to show for stages; it has checkboxes for several things including TWR. The top of the panel is all about TWR; it controls which body it's calculated for, and how deep into its atmosphere. Rockets always need a TWR over 1.0 to take off and to enter orbit. (Spaceplanes can get away with less within the atmosphere.) It can be interesting to play with the controls and see how things change. Some rockets - the ones with the best vacuum efficiency - lose a lot of power at Kerbin sea level, but experimenting with these controls shows they get quite good sooner than you'd think.

The closer your engines are to you center of mass, the better your thrust is going to be. Also it's much more stable when you've got wobbly engines.

[@Terminarch]

Instead of using Undo for copy, just hold Alt when clicking on what you want to copy. It chains down to whatever is attached to it.

[@sadboysuss]

when you angle the boosters towards the fuel tank in the first rocket, some of the energy is wasted as it's cancelled out by the other opposite thruster and the elastic force of the rocket

[@bradley9856]

In the early days of KSP, there was a weird bug/quirk in how RCS was first implemented. You could slap a RCS thruster on a small probe and get incredible amounts of delta V.

Ctrl+z is the undo command and even tho it can let you copy stuff it's easier to just hold alt and click the part or cluster of parts you want to copy

[@Radical_Larry]

You can turn off the fuel flow thing in the decouplers

[@odarkeq]

I've been able to correct for some of the 'oscillating' you referenced at 14:45 by turning off SAS and stabilizing by hand. When you have a high torque, the Automatic Stabilizer can over-correct and then have to catch itself, over-correcting again in the opposite direction and creating a feedback loop of oscillation. This was actually a problem for NASA in the Apollo 6 mission, and they had to solve it by putting a Kerbal inside the engine to lightly pinch off the fuel nozzle. The previous sentence is not true.

[@elisereichrath4162]

Pro-tip for stability: if you go into the game setting and enable advanced tweakables, you can assign auto-struts to make the structure a lot more rigid. They are a lot more stable than they used to be but your mileage may vary

[@theburgerbox9576]

you can copy stuff by holding ALT while clicking on a thing Its really useful

[@sebastianlippold9120]

At 15:20, another reason why it has so much delta V is because the isp increases the less atmosphere there is

Amazing Assuming that in KSP monopropellant is hydrazine, like in real life.. Well, each time these rockets explode in mid-air, an ecological catastrophe probably happens on Kerbin

A lot of the time when KSP "crashes" it can eventually fix itself given enough time. Anything that makes it lag too much will trigger the window prompting to close it, but if you don't close it, it will usually come back.

[@theneonbop]

Important so you don't have to deal with fuel tank priorities: you can set most decouplers so fuel can't travel through them, making the bottom stage not able to access the fuel from the top stage

Yeah monoprop will draw from all the tanks on the rocket regardless of stack separator fuel valve settings etc so you gotta watch your level yourself, its a bug. Its caught me out a few times when I use very minimalist service modules on return capsules/eve ascent vehicles etc where i set rcs to fore by throttle and use the big thrusters as orbital manoeuvering engines a bit like soyuz and find manouevers from earlier int he mission have drawn from the monoprop I thought I'd valved off and RCS thrust disabled correctly to ensure I have fuel left for final orbital docking or retro burns.
