FWIW I have looked at the "offsets" before. At one point they did work w/ the UIUC models, but I think more recently (last 4-5 months) they stopped working w/ the UIUC models. However, at that time, they did work w/ the other models. So I speculate that the bug seems to be FDM specific. It *is* broken w/ the UIUC models.It seems that a while back this came up when I was working on the viewer or maybe tweaking the original 3D aircraft model rotations. After moving the AC3D model origin to where Yasim wants it (at the nose) the aircraft rotates fine. (Note that it appears the gear still compresses abit too much as when doing Curt's throw on the breaks at 40kts test, the nose comes very close to the ground).Anyway, what I now remember is this: the camera position as configured for the chase view is always in relation to the FDM location. And in the case of Yasim that location is always the nose. So if the nose goes up so does the camera. In the air, this gives the _appearance_ that the nose is stationary during a pitch, and the 3D aircraft model moves with a kind of a wagging motion rather than a pitching motion. I understand that the motion of the aircraft is correct and the 3D model moves correctly when it matches the FDM, the problem is the way it looks on the screen when the origin is at one end of aircraft. Also, a bug report, for some reason the model "offsets" (e.g. /offsets/x-m) appear to no longer work.
