Ever since first flight my indicated airspeeds have been off. It gets worse as velocity increases. I have the Dynon AOA probe hooked up to my mechanical and GRT display (they agree pretty well). Static system checks out via an IFR check and flying in formation with other aircraft.
I'm wondering if the pitot tube itself isn't tilted up or down. That would definitely throw things off (I remember that from college days! we did experiments mounting pitot tubes at different angles in the wind tunnel).
I have the Gretz Aero pitot mast. Did any of you have to shim it at all? I just ordered a new one and noticed in the directions about adding a washer.
Wonder if there is a way to determine the correct angle... maybe with longerons level?
