Awaras Posted March 7, 2012 Share Posted March 7, 2012 I found out in another thread that it\'s bad to place SAS modules using symmetry because they cancel each other out and make the ship spin, but what about vertical placement? Is it better to have the SAS just at the top, under the command pod or is it better to place them somewhere in the middle, near the rocket\'s center of mass? If using multiple modules, should they be together or separated, one near the top, the other near the bottom? Link to comment Share on other sites More sharing options...
what-the Posted March 7, 2012 Share Posted March 7, 2012 I find that the top is generally better. Helps point the nose of the rocket where you want it to be pointing. Link to comment Share on other sites More sharing options...
Chairborneranger Posted March 7, 2012 Share Posted March 7, 2012 To my understanding the farther away from center of mass you place them, the more rotational torque they will create. Kinda like moving a mass on a seesaw lever. The farther you are from the fulcrum, the less force it takes to move the same mass. Just be careful, as without proper supports or solid design you can create some nasty vibrations if your craft is too long or too wide. Link to comment Share on other sites More sharing options...
marko dash Posted March 7, 2012 Share Posted March 7, 2012 or just not use them at all, since the ASAS was released i haven\'t needed a single SAS Link to comment Share on other sites More sharing options...
Ydoow Posted March 7, 2012 Share Posted March 7, 2012 I like placing my SAS/ASAS at the bottom. And actually, placing SAS in symmetry does NOT cancel the out.Attaching SAS radially and using symmetry does cause them to cancel out though.I think it\'s my post you read But what I\'ve recently started doing is placing the SAS/ASAS in a place that can be detached and at the lowest place i\'ll need it (first/second stage).My main boosters/tanks and engines will be radially attached off of a fuel tank below the command pod.I will attach a stack decoupler to the fuel tank below the command pod, and then the SAS module to the decoupler.Now all my tanks and engines are radially mounted (which gives super thrust). Once I no longer need SAS (I\'m in orbit), I\'m able to drop the SAS module from beneath the command pod Me likey efficiency. Link to comment Share on other sites More sharing options...
Neomex Posted March 7, 2012 Share Posted March 7, 2012 For me it always works best at the top, if it is not problem leave it there, if is, deteach at some top stage. Link to comment Share on other sites More sharing options...
