<DIV>Fortunately the modern pattern ship has evolved to a force arrangement that
minimizes optical perspectives. As Mike references, his turtledeck slopes
downward rendering the visual perspective of a low tail, but if you have
something like a P-51 where the aft lower fuse slopes upward and the stab is at
the top surface of the fuse, these two aircraft can be flying at the identical
AOA and present totally different visual perspectives. </DIV>
<DIV>So I guess the answer is to get a fuse shape that meets your criteria of
what looks right/good to YOUR eye and go from there.</DIV>
<DIV> </DIV>
<DIV>I, personally, design around a datum and use just a whisker more positive
in the wing than what is usually accepted as the norm. Of course the stab has to
be set to compensate for this, but the end result yields a satisfactory flight
angle and gives me a K.E. mix of 2% up on one side and 2% down on the other
(pitch), which I call neutral despite criticisms to the contrary by those who
try to tell me that I have a misaligned stab. I acquiesce to the misaligned stab
producing a rolling moment (of which I have none), but point out that the roll
effect would be in the same direction with both Rudder Inputs and should not
impact pitch.</DIV>
<DIV> </DIV>
<DIV>So there !</DIV>
