The Small Inline Reaction Wheel (previously named Inline Reaction Wheel) is a toggleable reaction wheel that provides torque to a craft. Extra torque means that the player's spaceship will rotate faster when ordered to, resulting in a more nimble feel to the craft. The Inline Reaction Wheel is the 'Tiny' size reaction wheel.

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” |
” |
However, this is not actually correct with rigid spacecraft. A reaction wheel should provide the same torque regardless of placement. However, off-center reaction wheels will cause very long vehicles, especially with docking ports, to bend, which can cause instability.
Product description
| “ | The inline reaction wheel system uses a series of spinning discs that are going "Very Fast", to generate the torque necessary to control a spacecraft without wasting any propellant. Please do not attempt to service this device while it is running. — STEADLER Engineering Corps |
