Do the fighters have the boost function?  If not, that would be a very useful addition for a couple of reasons.  First, it would help end the endless circling that fighters usually get into.  One fighter could boost out of the circling without leaving himself vulnerable to immediate attack by the other fighter.  Second, the maps are big, boost would enable people to get around the map faster which means more fighting and less flying from one place to another.

Also, in addition to the boost, the normal cruising speed of the fighters should be faster, at least twice as fast.  The fighters are currently unrealistically too slow.
