RCS in KSP2 Explained; Find Out What It's For

Kerbal Space Program 2 is a simulator of a space agency. The player gets a chance to build ships (and more) and sends them to other planets. The game is very popular, because it is one of a kind. KSP 2 is in early access state, so you have to be prepared that there are some bugs and not all functionalities are implemented. However, RCS is present in the game from day one. Nevertheless, it is not well explained. In this guide we will tell about this system.

What RCS is in KSP2

RCS is Reaction Control System. It helps to make small and precise manoeuvres. It is very useful in the case of docking or moving on the surface of other planets. However, you need to mount proper engines to use this feature.

How to use RCS in Kerbal Space Program 2

1. First of all, you can equip RCS engines in VAB (Vehicle Assembly Building) under category Utilities. They are not in Engines tab. It confuses many players, so they can’t find them. Remember also about monopropellant fuel.
2. RCS toggle – at the lower left corner there is a button which activates or deactivates RCS controls. You can find here more information about them.
3. RCS can be extremely helpful in the case of orbital docking. It allows to delicately change the position. Very useful in precise manoeuvres. This characteristic makes it also valuable as the part of landers.
4. Note: Players inform about some bugs using and installing RCS. For example using it makes the orbit unstable or combination of RCS an SAS causes the ship to spin. Remember that a strange behaviour of your RCS may not be a reason of your mistake, but a problem with the game.
