The Inline Reaction Wheel (previously named S.A.S Module) is a toggleable module that provides torque. 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 COM. 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.[1] They appear to function on a stability:mass ratio, and the effect can be enhanced by adding additional Inline Reaction Wheels. Often a single Inline Reaction Wheel isn't enough.
Each Inline Reaction Wheel adds 0.5 to the mass of your ship; if you require a lot of Inline Reaction Wheels to get a large ship off the ground, consider dropping them with your earlier stages when you no longer need them.
Although its internal part name is sasModule it does not provide SAS, but may be used by it.
Changes
- Increased torque (3 → 20)
- Renamed from S.A.S Module into Inline Reaction Wheel
- Weight 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
