1) The panel folder or CFG is wrong, like not pointing to the right folder or the gauges are not where it is being told they are, but I doubt it is this reason. 2) The model.cfg is not pointing to the correct MDL files. I would almost bet it could be this one. 3) The texture folder or the actual textures might be missing. This one is another good possibility.

I do have the textures and the texture file, but I noticed in the aircraft.cfg file that the SITM entry is not there.
