Newest newbie question ever...

[Bundyfly]

I have honestly tried to figure this out and can't...how do I fire liquid engines? I can lift off with solid boosters and separate when they are depleted but then I cannot fire my booster engines. I feel silly asking because I am sure it is something simple that I am not doing. Please help

[FanaticalFighter]

Are you sure the liquid engines are attached directly to the tanks? Generally, you just press space till the stage for liquid engines, and then press shift to throttle up.

Yeah, SRB's (the yellow rockets you started with) and liquid engines are very different:

SRB's have fuel and engine in the same part, and they are unable to throttle down until they run out of fuel!

Liquid engines require a fuel tank part. To use them, you press shift to throttle up, and then space to activate (when they are in staging.)

Watch Scott Manley's* videos for beginners!

(If you don't know, Scott Manley is pretty much KSP's Holy Saviour. He is so good at the game!)

Good luck!

With Love,

Might want to check out the in-game tutorials they might be a bit old but they still work.

Make sure your throttle is at 100% by holding shift and watching the throttle rise to the left of your navball. Hope this helps!

Either you don't have fuel, or you did the oposite and have fuel but no engine. Solid boosters are a single thing, but liquid boosters need both an engine at the end and fuel tanks ontop of the engine

Or you are using the plane fuel tanks (plane tanks have only liquid fuel. For a rocket you need the version with liquid fuel and oxydizer)

Or you forgot to throttle up. Solid boosters don't need to be throttled because they always fire at 100%, but with liquid boosters you can deceide yourself how hard the engines burn. Shift throttle up, ctrl throttle down. Your throttle is the little bar on the left side of the navball

Most likely you forgot to throttle up. Happened a friend of my.

Press shift to raise your throttle, then fire. Also liquid fuel boosters run on liquid fuel tanks. If all else fails, then use moar boosters.

Make sure that the engine is directly under the tank, you throttled up and have the engine in the right stage. Don't worry, I'm new too, and the kerbonauts never seemed to mind when my engines failed. Granted, they were dead, but you have to take the good with the bad.

Don't let the abundance of knowledge on the forum intimidate you, Bundyfly. There are no stupid questions here. Help is right around the corner.
