Just to tell you guys a fun trick:
If you move a ship towards the center of a grav well, and then have it move up or down in a manner which causes the angle of ascent to skim the edge of the planet in question...
...the ship will move up (accelerate) VERY quickly to the top/bottom of the planet, you can have it do the same towards the opposite pole immeadiately after it reaches the zenith... which will basically make your ship move over and under the planet and exit the opposite side really quickly... w/ proper waypoint set up you can typically do this faster than anyone can respond- and it will give you a good head start on an escape to a repair bay on the other side of the planet or what have you.
This doesn't seem to work going around the planet horizontally.
Why? It's a nifty side effect of how SOASE works... your ships move faster towards the center of a gravity well and slower when moving away from the center of a gravity well... which is something a lot of people forget about! That and I think that the Z-Axis acceleration is also likely a bit quirky.
Also, I made a post about how to use the Z-Axis a long time ago, which you can find here, in reply 5.
Yeah... the TEC/Advent starbases need to be able to rotate along all directions so that it can bring it's full firepower to bear on a target above/below them. As for range issues... that's just something the game is quirky with on the Z axis, everything seems to have a longer range than it should (except apparently, starbases and structures judging by this thread). I'm sure they could synch the distances up properly by tweaking a few variables somewhere.
I've never really tried it, but when placing structures, can you adjust their Z-Axis placement?

PS: I totally agree that using the Z-Axis to invalidate mine fields or abuse the firing arcs of TEC/Advent Starbases is 100% complete and total bullshit. IMO, mines should have Z-Axis movment, and spring up or down really fast to catch ships going above or below them (just measure proximity via the XY distance)... it seems like the simplest solution for mines.
