Talk:Advanced Reaction Wheel Module, Large
Does the visual appearance of the attachment node make a difference in the behavior of a part? This part is a large diameter but only a medium attachment node in the Vehicle Assembly view.
- It's purely a visual effect, IIRC. Nothing about compatibility or strength. UmbralRaptor (talk) 12:35, 16 November 2013 (CST)
Should the picture in the box be replaced for consistency? It is a png, but I don't think I should update it, since it is more of an application example rather than a part diagram. — Chuzzard (talk) 18:22, 2 May 2014 (CDT)
ASAS vs reaction wheel
With 0.21 the idea behind ASAS, SAS and reaction wheel didn't changed. They were just renamed (and the PID values hidden): ASAS becomes SAS and SAS becomes a reaction wheel. I haven't tested it yet specifically but I don't think this doesn't work as a reaction wheel, especially as it has the torque values defined in the part configuration, so I see no reason why there should be no torque introduced by this part.
I'm also not sure how this part might confuse older players. It still has SAS functionality which is (for old players) the ASAS (like in the name) so for those nothing changes except that this part could produce torque.
Stability in large launches
There is a stability problem when the torque from reaction wheels and the gimbal from big engines is combined during early stages of big rocket launches. To reduce it is recommendeed to disable reaction wheels at the first stages. This may be added as a little advice.
