So far as I can tell, this part does not provide SAS. Am I doing it wrong...? — Preceding unsigned comment added by TerryDactyl (talkcontribs) 20:03, 3 March 2015‎ (UTC)

Nothing, if you look in the infobox on the right it says that it has no SAS level ;) The description is wrong, if you like you can fix it. — xZise [talk] 05:07, 4 March 2015 (CST)

Usage section conflict

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.

Why is the wiki presenting two completely opposite viewpoints? If one is correct and one is incorrect, we should only be using the correct one; if we don't know which one is correct, then we shouldn't make statements that sound like we know exactly which one is correct. I don't know enough about reaction wheel placement for this, can someone else explain what we know about them? AlpacaMall (talk) 00:35, 12 July 2021 (UTC)
