Very High IAS Readings Dynon D180...
I just bought a flying RV-12 and the airspeed is erratic and reading way too high. I did the zero adjustment for IAS in the Dynon D-180 and it didn't help. Now I'm thinking the static ports are blocked. I cut a small length of .032 safety wire to investigate the static openings and it indeed appears they are block. Possibly blocked when painted. Can someone tell me the correct drill size for both static ports on the RV-12 so I can check and open if necessary? I searched the drawings and don't see any reference to static port opening.
