For those of you that dont know, there are a few spawns scattered about the galaxy that give pretty decent space xp with little or no risk to the flyer.
Tier 1 - tbh, dont bother, the good stuff takes too long to kill, and your better off just doing duty missions etc.
Tier 2 - My fave is in Lok space, there are a few spawns of tier 3 bloodrazor etc. which are non aggro and will idly just fly around whilst you blow thier mates to bits. I use this one.. (-2145, 6465, 3324) Most of the POI's in corellia, tatooine, naboo etc will suffice too.
Tier 3 - I have 2 spots which I use almost exclusively. 1st is in Dath space, about 2k away from the space station, there are 3 corsec tier 4 z-95's circling, with another 3 about 2k away, kill them, fly to the next 3, kill then, fly back, repeat. (-5414, 2360, -3072) & (-5331, 1892, -1663) 2nd is in Kasshyk space, hyper to the avatar platform and fly past it about 2k past the station is a swarm of tier 2 and 3 Blackscale fighters and bombers, all with the usual non aggro thing going on. (4300, -800, -4400)
Tier 4 - Any of the Kasshyk POI's are good, but my personal fave takes a while longer, but is by far the easiest spawn in the universe.
In Endor space, there is a spawn of Kimogila bombers, they warp in, fly 2k in a straight line and then hyper out, with one appearing every 15-20 seconds. Position your self by the exit point, (2504, -1289, -2639)), point at the spawn point (1409, -505, -2876), wait for the 1st sucker to get in range and blast them to bits. If you have a bit of firepower (rhyk, x-wing etc) then you should be able to blow them to bits way before they get to you or maneuver out of the way. The loot here is good too.
