Where are you placing the coordinate origin of the aircraft? There was a confusion/unification about this recently, with the consensus being that the origin should be, by convention, at the front of the aircraft (either the nose or the firewall, depending on who you ask). Strictly, the coordinate origin of the aircraft and the 3D model should be exactly coincident (or as coincident as practical, given that there are multiple FDMs and a model file that all have to agree). If the UIUC models are reporting an altitude of zero while on the ground, you'll see this effect. The real altitude should be a few feet -- however high the nose rests off the ground.
