There is a README.yasim in the base package, in the Aircraft-yasim directory. The YASim coordinate system is "X forward, Y left, Z up". Basically, point your right hand away from you like a gun: your forefinger and index finger are the X and Y axes, your thumb is Z. > My start point for the coordinate are those of ac3d.

You should definitely pick the same point that you use for the model origin in ac3d. > Moreover: does the location of a gear refer to the centre of it?
