Is the ground Speed measuring only in the Z direction? On my LER it can travel in the x axis. Even though the thrust amount and direction look good my GS is only .35 but when in the full Z straight forward it goes 10.
 
Ground speed is the length of the vessel velocity vector in the ground reference frame. It is independent of the vessel orientation. To test, put a vessel in orbit and note the ground speed when it is pointed in the prograde and orbit normal directions. They will be the same.
 
Do you define the Z and X as surface's or vessel's longitudinal / lateral axes, or are they from local / global reference frame?

I've just tested LER, and the max ground speed is the same while moving east, north-east, north, north-west, west, south-west, south, or south-east of the Moon, so I don't think you meant the surface axes. If you mean the vessel axes, then it moves forward with top speed ~20 m/s, backward ~13 m/s, doesn't move on sides, and rotates about 26 degrees per minute for me, and rotation or translation rcs modes don't change anything. Aha, and it's for the updated module of LER.
