Yes there are differences.  The IV and ES molds were hand made.  The Evolution brought Lancair into the 21st Century with CAD designed
and routed molds but they seem to have no interest in making new molds
for aircraft they no longer aggressively sell.
So here we are living and loving our orphans.  Second time for me: I
built a GlaStar just before they introduced the Sportsman.

Subject: Why is ES upper left fuselage not symmetrical with right side?

All,

It has come to my attention through a person we were considering
contracting to do our interior that the left and right sides were not
symmetrical in the measurements from the window bottoms on each side to
the centerline of the roof.  Upon closer inspection we realized that the
left side was taller than the right, in particular where the door hinges
are attached.  However, when looking at the base of the windshield in
reference to the cowling, it looks symmetrical.

Does anyone else have this? If so, is it designed so because of the
P-Factor (only good reason I can think of)?  Also, the windshield had to
fit into the existing curvature without issues I suppose.  The plane
flies wonderfully, trims up hands free through the entire flight
envelope so I am not too worried, just curious.  Then again, maybe they
did that to accommodate the left side ego.
