The FL-R25 RCS Fuel Tank provides fuel to the spaceship's RCS thrusters.


RCS fuel tanks provide fuel for all RCS thrusters of the ship. There is no need to place the thrusters directly on the tank. If there are several RCS fuel tanks the lowest will be used first to avoid jettisoning full tanks while preserving empty ones. Similarly, RCS tanks are emptied radially from the outside in. Within a stage, radial position takes precedence over vertical.

Be aware that RCS fuel tanks do not have a built-in feedthrough for regular liquid rocket fuel, so you will have to either place your RCS tanks on the nose of your rocket stages or make use of fuel pipes.


These fuel tanks carry pressurized gas propellant for RCS thrusters. New advances in plumbing technology made it possible to route RCS lines to any point in the ship. So unlike liquid fuel tanks, RCS Fuel tanks can be placed anywhere.
