Hi everyone, New guy here. Bought a very nicely built RV6 in September and now have the RV grin! One problem though, it does have a significant IAS error. About 10 knots fast at 170kts TAS both AS indicator and has a RMI indicator showing the same error. I did have a static leak inside the plane, fixed that, thought that would be it but only dropped about 3kts. Static is at the pitot-static tube mounted at the typical place under the left wing and extends down the same amount as a fiends RV4 that does give known good indication. I checked the static ports around the pitot, all clear. Thinking this thing might not like the static taken under the wing?
