REFLECTOR: TAS calibration?

[Geoff Gerhardt]

Guys,

My pitot/static is positioned under the canard - I suspect it is seeing
increased pressure at high speeds thus giving me a low indicated airspeed.
 This weekend, I thought I was smart and put a small static port right
ahead of the dog house thinking that was a great place.  After a quick
flight where my air speeds were through the roof, I realized that that spot
was actually doing the opposite and was creating a low pressure region as
the air bends over the nose.  I see now that I need to find a place on the
flat section of the fuselage to put the static port.

Where does everyone else have their static port?

Thanks.

Geoff
