The Advanced S.A.S Module, Large is a large diameter reaction wheel meant to stabilize and help keep a rocket on course. Since virtually every command pod in the game already provides SAS, the torque is what will interest most players. Extra torque means that the player's spaceship will rotate faster when ordered to, resulting in a more nimble feel to the craft. The Advanced S.A.S Module, Large is the size 2 reaction wheel. It is expensive, relatively heavy, and provides a very large amount of torque compared to the other reaction wheels.
This module was previously used for ASAS module functionality, hence it's name. It was never meant to produce any torque, it was only meant to function as a computer unit, a sort of autopilot to keep the ship on course. Since 0.21, it has been changed into a reaction wheel. There are several problems with this, however. The reaction wheel is still totally hollow, so there doesn't seem to be any way for the module to actually generate torque.[dubious] The KSPX mod, from which several parts were implemented from 0.19 to 0.20, includes a solid "SAS module, large". Unfortunately, the mod's developer left Squad before the SAS redesign, so her mod could not be implemented.
|“||After many years of research, STEADLER Corps rocket scientists discovered that Kerbal crewmembers just can't be trusted to keep a spacecraft under control. The Advanced S.A.S Module adresses that issue by correcting flight controls continuously. It is highly recommended that crewmembers are kept unaware of the presence of such a device, as experience shows that many Kerbals will see that as a 'challenge to their flying prowess'.||”|
Before the SAS was redesigned, the “Advanced SAS Module” (now the Advanced Inline Stabilizer) and the “Advanced SAS Module, Large” both functioned similarly, the only difference being the PID values and dimensions. They still function similarly, however the description seems to indicate that the “Advanced Reaction Wheel Module, Large” works like an old ASAS module instead of a reaction wheel. This may confuse older players who are returning to the game.
