Ok i get it now, thanks dv2 Thank you too, you helped me a lot, talking with you is helping me think as well. In the rocket gimbal, the turret is full of reaction wheels, perhaps because the rocket gimbal is large and heavy and needs big reaction wheels. But in the laser turret, well they must be in there as well, just not so large. So it seems there must be four just like you mentioned. Okay don't mean to keep you.

The reason, I think, that turrets and engine gimbals use reaction wheels in the first place is that qswitched didn't want to worry about conservation of angular momentum for the whole damn ship. It'd also be an extremely hairy problem for the people writing the fire control software if this was real, so they might decouple the turret from the ship and use reaction wheels (or CMGs) for super-fine adjustments. It probably helps to have control in all 3 axes, so that you can damp unwanted roll so the turret/engine doesn't start precessing. The roll reaction wheel probably could be a lot smaller than the other two.
