This RCS thruster allows thrusting in any direction sideways to it. Placing four thrusters of this kind is sufficient to rotate and translate the craft in all directions, but then are only good for one them. In this layout the translation force along the roll [[axis]] is twice as high as the two other axes usually.

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 physicsless part that adds its mass and drag to its parent 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.
