Actually the 3D model is fine.
This is from the YASim config file for the pa28-161. Note that the origin is
always 0,0,0 in YASim. So in this case it is 0.5 along the X axis which is
the longitudinal axis:
<fuselage ax="0.5" ay="0" az="0" bx="-7.75" by="0" bz="0"
width="1.5" taper="0.2" midpoint="0.3"/>
Change it to this:
<fuselage ax="0.0" ay="0" az="0" bx="-8.25" by="0" bz="0"
width="1.5" taper="0.2" midpoint="0.3"/>
What I have done is move the fuselage back half a meter. I am not sure what
do do with the "midpoint" value but iirc it is a ration and not a dimension.
In the rest of the config just subtract the 0.5 from each "x=" value and you
will have the same exact flight model only the origin is at the nose (there is
probably about a dozen of those to change).
Best,
Jim
