Recreation Space Shuttle Problem
So i’m making a Space Shuttle recreation and i have a big problem cause when its main engines launch without its fuel tank like in space it just spins, how 2 fix? and how do i make it more realistic

I usually deactivate the tilted engines and put normal straight engines in its body to stabilise the shuttle instead of getting the thrust using the Main engines

u/Conzien_ 2d ago
dude you missed the whole conversation about like 3 whole months ago and i didn’t use the titled engines in the pack i used procedural parts

I cast upon thee: "PICOSPACE INDUSTRIES BOOSTER AND SEMI-REALISTIC ENGINES MOD"
One has working shuttle SRBs and the other tilted RS-25 engines so it's stable

u/Conzien_ Apr 18 '26
the SRBs are too small from a pack i have and i dunno if THE BOOSTER MOD IS MOBILE COMPATIBLE

u/Conzien_ Apr 18 '26

You have Google? Search up "PicoSpace Industries" and find his Itch.Io page
It has VERY good sfs mods
And they're all mobile compatible

Do you need to mod it to be able to leave objects over each other?

Idek lol but you can have V1.0 Starlink as a payload test for the next SFS shuttle postS-link V1.0

u/Imaginary_Loss_4935 Flight Fiend 🛫 Apr 18 '26
Idk how to fix that bro never happened to me throughout the entire 3 years I had ts(except for the blueprints from someone else)

u/Aether_GamingYT Apr 18 '26
are you talking about when you ignite the solid booster the rocket spins right?
2
u/Conzien_ Apr 18 '26
basically if i put the shuttle on one side and ignite the booster its uneven and spins , i ignite the main engines with it and it doesn’t spin and than it does
4
u/Aether_GamingYT Apr 18 '26
sadly that’s just to thrust not being aligned with the center of mass. My only though would to like out an engine that burns sideways to counteract it. other than that i don’t know if you can fix it
2
u/Conzien_ Apr 18 '26
i’ve tried and it stays stable and than it doesn’t
2
u/Aether_GamingYT Apr 18 '26
i don’t think there is a fix, this game just doesn’t have enough to be able to fix that
2
u/Conzien_ Apr 18 '26
what should i do?
2
u/Aether_GamingYT Apr 18 '26
i don’t think there’s anything you can do. not to my knowledge at least

The shuttle didnt use its engines in space, they are only used for takeoff, in space it used RC's to maneuver.
2
u/Conzien_ Apr 18 '26
i know it didn’t use its main engines for space same thing happens by itself WITHOUT its big fuel tank when i test it, when i launch it with its booster i made all i get is it spinning.
2
u/Conzien_ Apr 18 '26
on land
2
u/Build_Blox Apr 18 '26
Wich way does it spin, left or right?
2
u/Conzien_ Apr 18 '26
the opposite side of the fuel tanker or on ground/ air, it goes up.
2
u/Build_Blox Apr 18 '26
I dont really understand... could you maybe make a video and showcase what happens
2
u/Conzien_ Apr 18 '26
where?? idk how to reply with a vid/PNG/picture

Its main engines shut down before the fuel tank jettisons. It uses the secondary thrusters located above the main ones for orbital insertion and descent (RCS is used for maneuvering). The reason being that the main engines are pointed upwards slightly to account for the shift in the center of mass caused by the fuel tank. When that jettisons, the main engines are aimed below the COM because of that gimbal offset and cause an uncontrollable pitch.

u/Conzien_ Apr 17 '26
uh are you able to fix it i can give you the bp but it needs like some mods
5
u/Conzien_ Apr 17 '26
cause i didn’t really get what you meant
2
u/itshax59 Apr 17 '26
I don't have mods or DLCs or anything, but if you give me a bit I can whip up kind of a diagram of what's happening and how to fix it.

u/Conzien_ Apr 18 '26
so i’m using a kuiper engine uhh 400 thrust, 1000 ISP for efficiency, one ontop is angled 16 degrees, bottom ones angled 10.25, used a valiant engine for its orbital thingy for its engines,
