Randy -

If memory serves, the data Scott sent regarding placement of the static ports is slightly
different than what was in the early 235 manual. Unfortunately I don't have my 235 manual
anymore so I can't absolutely swear to that. However, when I built my 235 back in
the late 80's and early 90's, I Lancair recommended using the two-port system
at the same vertical location as in the 320/360 manual but, I believe, wanted them located just
aft of the rear lower cabin bulkhead. I'm guessing but it may be that the
shape of the fuselage in that area is slightly different between a 235
airframe and the later 320/360 a/f, perhaps producing a difference in the
pressure field there. In any case, my CAS vs IAS is acceptable and
relentless testing back in the day shows that, at least for the 235, those
locations are good.
