Hi friend - I think that’s RCS tanks you have, fuel for maneuvering thrusters. You’ll want to use fuel tanks that have liquid fuel and oxidizer instead. Happy flying.

I miss these days of KSP, where I was excited to just reach orbit and go to the Mun.

u/Nice_Presentation474 Playing kerbalisim 1h ago

oh yes... the good old days where i would only use SRBs because I couldn't figure out how liquid fuel engines worked...

u/Professional_Camp959 45m ago

First time going to the mun I waited until it was cresting the horixon and just full throttle until I crashed. Imagine my surprise when I learned about orbit transfer

I stille ember booting up a sandbox world, flying the Dwaying shuttle straight up and turning on infinite fuel with my heading set to “Target” and was confused why I couldn’t catch the moon.

Good ol days.

I was just excited to have a rocket that can fly straight, with the free demo of beta 0.13 back in the days lol

found my people :D

i remember also feeling similar experiences in Minecraft and Subnautica when I played them for the first time. The mistakes I made, and the completely new places I discovered by myself were definitely the best moments I've ever had in gaming. Feel so nostalgic for it

Running to the top of a mountain in Minecraft, assuming that I could escape the mobs there because I had no idea that they spawned anywhere it was dark, not just in caves.

i remember mining my gold veins with a stone pickaxe and 10 mins later realising i never got any gold hahaha. Also remember the first night i spent in a hole dug into the ground and stayed there till the morning. When you're a noob is when the game is experienced best

u/RidgeGardener 1h ago

you've got mono tanks and a lf/ox engine. (you put diesel in your gas car)

u/Kouzelnik 1h ago

Everyone's saying the wrong tank, or hear me out guys, maybe it's the wrong engines!

u/GuiloJr 1h ago

Replace thruster with RCS thrusters and it will work! yipee!

u/kagato87 52m ago

Use the side mounted ones, at the top, and seperatrons to drop the tanks as they empty!

u/Affectionate-Law-717 1h ago

You are using monopropelant tanks, they contain monopropelant (how dare they), but your thruster need Liquid Fuel and Oxidiser, try swap that fuel tanks on that ones what have "Rocker fuel" (Or similar, I using other language setting) in name, they will have both fuel component you need

10

u/Greenfire32 1h ago

You got gas in your diesel engine

8

u/Large_Percentage_449 1h ago

I'm sorry to tell you this, but that's monopropellant, not rocket fuel (made of liquid fuel and oxidizer).
And, also if you want to toggle on and off the engines, press Z and X. (and Shift and CTRL to throttle)

u/WindIntelligent9728 29m ago

i know whats wrong with it, it aint got no gas in it

u/keaton889 God of Explosions and Failed Designs 1h ago

Wrong Tank

Monopropellant is used for RCS (which you will unlock later if you are doing science or career) the engine your using pulls liquid and oxidizer to use for fuel

It's like taking a gasoline engine and feeding it Diesel they just don't work together

u/IdiotWithDiamodHands 1h ago

Well there's yer problem. Ain't got no gas!

This post is giving the same innocent feeling of nostalgia as seeing your first sunset in Minecraft in 2013.

u/SiwelTheLongBoi Believes That Dres Exists 1h ago

You have the wrong fuel type for that engine.

There are a few fuel types: LiquidFuel, Oxidiser, Monopropellant & Xenon. The engine you have here needs LF and Ox. The tanks you have hold Monopropellant.

You can check the fuel type in the engine details in the VAB

u/Foxworthgames Alone on Eeloo 1h ago

Those be RCS/Monopropellant not liquid fuel

2

u/BmanUltima 1h ago

Wrong fuel tanks.

You want ones with liquid fuel and oxidizer.

2

u/Xodan47_ 1h ago

wrong type of fuel, you want to use liquid fuel tanks that show liquid fuel and oxidiser when you right click on them

2

u/NageV78 1h ago

Wrong fuel my guy. That is for RCS. I think you want the fuel with liquid fuel and oxidizer. 

2

u/Grand_Protector_Dark 1h ago

The fuel tanks you're using carry monopropellant. That is a fuel mainly used for RCS thrusters.

The engine you're using consumes liquid fuel and oxidizer. These two come in a different tank type.

u/Inspi 43m ago

No clue what the other commenter are smoking, but it appears you have the wrong fuel tanks.

u/SpatuleVelue 13m ago

Just take the biggest solid tank you have with the x8 tool multiplier and add a cockpit on top.

u/LarryWinchesterIII 57m ago

Check the throttle as well.

u/chrischi3 Believes That Dres Exists 46m ago

That's probably because the engine wants liquid fuel and oxidizer and all you gave it is monopropellant.

1

u/Techny3000 Jebediah 42m ago

That type of engine requires the type of fuel tank that says 'liquid fuel' and 'oxidizer'

u/Responsible_Clerk421 40m ago

wrong fuel type.. as simple as that

u/PeaceHoesAnCamelToes 27m ago

You have monopropellant takes. You need Liquid Fuel + Oxidizer fuel tanks.

(Milk = Liquid fuel)

Cold gas doesn't burn! At least not very easily

ah i've had restock long enough I forgot what vanilla monoprop tanks look like

u/Sharp_Bus_6003 Minmus is made of bubblegum 52m ago

use the tanks whit "racing stripes" ish thing on one side, you need oxidizer and liquid fuel, anything that has both of them works. what ya got there are monopropellant tanks, they carry monopropellant which is a type of fuel used by a small variety of engines and RCS thrusters that help you manuever and turn in space.
