Static Air Source
The outside static source really looked neat, but during my airspeed calibration tests I discoved errors of almost 20% at higher indicated airspeeds. I had placed the static port in an area of low pressure which became even lower as speed increased. When I disconnected the static port and vented the pitot/static instruments to the cabin, subsequent testing showed indicated airspeed correct to within a couple of mph over the entire spectrum.
Another change that I made around this time was to replace the airspeed indicator. The kit was supplied with an airspeed indicator which read from 0-200 mph. Since my Vne (never exceed speed) was 140 mph and most of my flight maneuvering occurs between 0-100 mph, I was only using about 1/2 of the guage's travel. I reasoned that if I replaced the indicator with one which read 0-140 mph, I would get better definition in the lower speed ranges where I needed it. So I did.
