Quote:Right. You have one or more fixed pylons supporting a ring that rotates around them.
Wait, what? The bearings are at the outer end of the sails, right? The ring and its pods are the only thing moving relative to the rest of the ship. Since the ring has to be balanced to be structurally viable, the position it's in has no bearing on the mass distribution of the ship - at which point, you can just bolt your reverse thrusters on port and starboard and, since they're inside the radius of the ring, they never interfere with it.
And you're right, we can attach the phased-array antennae to the outer surface of the ring instead of using the mast arrangement.
The reason I mentioned a central-bearing ring interfering with maneuvers wasn't for centrifugal force reasons, but for the simple fact that exhaust from the thrusters might impact the moving pylon. I'll work up a new sketch tonight (don't have Illustrator here at work).--
