Well, yes, but however we adjust the AI or the view angle or the 3D
model, the fact remains that the plane is pitched up 5 degrees when
it's on the ground.  I'm not sure that's right (the LaRCSim C172 has
the same problem).

Once it got fast enough, maybe, but I didn'tt think a C172 should take
off at 70 or 75kt at neutral trim without some elevator pressure.

Could it be that Tony is using the length of the front strut fully
extended rather than the compressed length?  When I do nothing but
shorten the strut by 4 or 5 inches, everything falls into place as if
by magic: the 3D model sits level on the ground, the AI reads
correctly, the plane's takeoff is much more like the takeoff in FLY!,
and I can see the runway over the panel.


All the best,


David
