The Inline Reaction Wheel (previously named S.A.S Module) is a toggleable module that provides torque and SAS. It is one of the parts featured in the demo version of the game.

Description
“ | The wheel adds assistive torque to a spacecraft, at the cost of electric charge — Unknown |

Usage
“ | The placement does matter for reaction wheels. Generally speaking they can cause some problems if placed far from the center of mass. Imagine you are grabbing that point and rotating it. That is what the reaction wheels will try to do. You'll get offcenter rotation anywhere other then near the COM. — comment by C7, in his blog entry “Updated Information on SAS in 0.21.1” |

Each Inline Reaction Wheel adds 0.12 tons to the mass of your ship; if a lot of Inline Reaction Wheels are required to get a large ship off the ground, it should be considered to drop them with earlier stages when they are no longer needed.
Changes
- Mass decreased from 0.3 to 0.12
- Torque decreased from 20 to 8
- Increased torque (3 → 20)
- Mass decreased from 0.5 to 0.3
- Renamed from “S.A.S Module” into “Inline Reaction Wheel”
- Mass increased from 0.07 to 0.5
- Costs electric charge
- Retextured
- (Undocumented) Mass reduced from 0.8 to 0.07, cost reduced from 2300 to 600
- (Undocumented) Torque increased from 10 to 20, Ki/Kp/Kd changed from 1.0 / 3.0 / 5.0 to 0.0 / 5.0 / 3.5
- (undocumented) SAS now use angular momentum instead of angular velocity - takes into account inertia momentum of the ship [1]
- (undocumented) Tweaked Kd, Ki and Kp parameters
- Exposed Kd, Ki and Kp parameters for tuning the SAS module
- SAS toggle with 'T' key
- Initial Release
