Hi guys
According to my calcs, the centre of the rear spar is not dead on 75% chord.
It is on 75.27%. Using compufoil I placed the rear spar at this location and
set it to distended depth. I then worked out that the tallest part of the
spar would be at 74.088% chord. This also happens to be the leading edge of
the spar.At this location the spar is 4.409" tall or 111.98 (112mm). Is this
all correct? I have gone over this three times now and something tells me I
am missing something. I suppose I should mention that this is for the stub
wings using the AS 5048 airfoil. Sometime in the past I worked out something
in the region of 117mm if my memory serves me correctly. I sure hope that I
AM missing something because I have a rear spar ready for installation built
117mm tall!!! HELP??
