Reaction Control System

From ΔV: Wiki

The Reaction Control System(RCS) is a set of 8 thrusters, 2 pointing in each direction.

RCS allows your ship to perform fine maneuvers.

RCS consumes propellant, heat and electricity.

All thrusters take 4 hours to repair* and 1 hour to replace.

*The number of mechanics you have hired affects repair time. See Category:Equipment for more details.

K37s start with RA-K37 thrusters, coming in at a usable 200kN thrust. The RA-K44 thrusters are a good cheap upgrade, but 'excessive wear' matters and they break down a lot faster. It might be better to 'downgrade' to one of the less efficient higher power systems (NDVTT or NDSTR). It takes a lot of fuel rods to begin handling the upper range systems, but once you get there, the MA350HO is a great system so long as you don't need gimbles. You need gimbles if your thrusters are melting things you are trying to pick up with your manipulator arm.
