# Rational Resources RCS Family
This modlet enables all supported RCS thrusters to receive multiple propellant options that they may be useful with the diverse ambient resources that occur on RR supported planets. Some of the MonoPropellant RCS options are treated as cold gas and not catalyzed. The (lack of) impulse on such options is very clear.

> :small_orange_diamond: = Given values are for reference and will scale with the original thrust and Isp of the affected engine.

> :bulb: This mod involves an opt-in system. Parts must be tagged and correctly in order to be handled. Conflicts or undesirable overlap (duplicate patching) have been observed with mods including Nertea's Cryogenic Engines, and the Kiwi Tech Tree.

> :bulb: WBI Classic Stock is supported.
