== Usage ==
RCS thrusters are used to rotate and translate the ship, and can do so outside of the atmosphere unlike canards and control surfaces. They need fuel from an [[FL-R25 RCS Fuel Tank | RCS Fuel Tank]] but do not need to be placed on the tank itself, unlike the larger engines. When you don't want to spend fuel you can toggle the RCS thruster system on and off with the R key. RCS thrusters work together with the [[Command Pod Mk1 | Command Pod's]] reaction wheels and the [[Advanced S.A.S. Module|Advanced S.A.S.]] system.

This RCS thruster can produce a force in any of the directions its nozzles are pointing. Four of these blocks equally spaced around the center of mass of a vessel is typically enough to allow a small craft to rotate and translate in any direction, but larger ships often require more. In the current paid version (but not the 0.18.3 demo), it has "PhysicsSignificance = 1", making it a zero drag and [[massless part]].
 
 
The little cold gas thrusters are still powerful enough to be used instead of liquid engines for major orbit changes with smaller ships. This capability will be useful for docking (planned in future versions). For adjusting heading, it is helpful to have the [[S.A.S.]] on to prevent unwanted rotation.
 
 
 
The positioning of your RCS thrusters is very important. They should be placed as far from the centre of mass as possible to give them maximum leverage. You should to mount at least 4 RCS thruster blocks around the nose and tail of large rockets. Beware, they will be fatally damaged if they brush against the ground.

The RV-105 RCS Thruster Block is a part with four RCS thrusters used for spaceship rotation and translation movement and is fuelled by monopropellant.

Usage

This RCS thruster can produce a force in any of the directions its nozzles are pointing. Four of these blocks equally spaced around the center of mass of a vessel is typically enough to allow a small craft to rotate and translate in any direction, but larger ships often require more. In the current paid version (but not the 0.18.3 demo), it has "PhysicsSignificance = 1", making it a zero drag and massless part.

Product description

The recent discovery of a third law of physics made it possible for STEADLER Corps engineers to produce these small monopropellant thrusters, to help with attitude control and linear motion. Even though many Kerbal physicists still dispute the validity of this new law, studies show that the thrusters seem to work as advertised.

The third law of physics referenced in the quote is likely a reference to third law of motion, which says that every force generates an equal counter-force. That's exactly how monopropellant thrusters or rather any kind of reaction engines work: When expelling propellant with a specific force, an equal force pushes the spacecraft in the opposite direction.
