Both RPM gauges work as does the slip indicator though the gau gives the appearance of being tilted slightly right giving the impression the slip gau is showing a left slip but the needle is on the central mark.
The gauges as far as I can tell are all built into the model as there are none in the panel.cfg that are visible in the VC so if it works for some people it should work for all, forget the air file and aircraft.cfg as far as I know there is nothing in there that would stop gauges working in this case.
Brian re twitching on taxi back up whichever aircraft.cfg you are using, locate contact points and replace point 0 with this one
point.0= 1, 14.610, 0.000, -4.590, 1181, 0, 0.864, 45.000, 0.100, 2.510, 0.800, 2.500, 3.000, 0
this one that came with the download has a rigid nose wheel leg with no damping
point.0= 1, 14.610, 0.000, -4.590, 1181, 0, 0.864, 45.000, 0.100, 2.510, 1.000, 2.500, 3.000, 0
the 1.000 after 2.510 is rigid, I changed it to 0.800 which allows some damping.
I replaced the contact point but still see the twitch. I even lowered the value to 0.5 but still see the twitch. It must be my possessed version of FSX acting up again. 
(time passes) Ok, just went back to the Meteor. Yes, this occurs at all airfields and the twitch is visible from outside the aircraft. I noticed that the twitching seems to be generated by the mains...I could definitely see the mains bouncing up and down slightly. I applied your dampening suggestion to the contact points for the mains and viola twitching gone. 
I appreciate all of your help Rich.
