Sartha
Power requirements peculiar to the Sartha meant that acceleration compensators were powered subordinate to the neutron guns. This meant that maintaining a full charge in the guns reduced the ship's ability to maneuver without burning RCS propellant. A pretty nimble little light fighter was reduced to the maneuverability of a heavy medium at best. The best Sartha pilots operated on half charged guns, and drained RCS fuel at a prodigious rate, reducing their combat range and hitting power, but allowing for greater maneuverability.
Of course, the Kilrathi (as always) figured this out faster than we did. Over Miliput, I had a Sartha pull this insane high-G maneuver, getting on my tail and just STAYED there. I let him be, figuring he didn't have the charge to maneuver that agressively AND hit me (very hard) while I worked over his mates.
Too late, I realized this guy mounted a quartet of high velocity stormfires whose minimum power requirements made Swiss cheese of my backside while that damned Sartha hung on my six through every possible evasive maneuver like he had been painted on the canopy at the factory.
