Hi guys, I have an RV-7 with the Airspeed Indicator from Vans (Knots outer scale and Mph on inner scale, not lighted).
The aircraft is 1 1/2 old and the AI, since two or three months, is more "erratic", it means that when it shows 120 Knots, for example, it "flutters" around 118-122, morover when the aircraft is completely stopped (engine too), the indicator does not go on 0, but stays more on the right, near the 30 knots (no wind, in the hangar of course!).
Not a big deal (stall speed and general speed have been checked on a square track with GPS and they are OK), but I wonder if the thing can become worse or if somebody had the same problem.
Thanks
Luigi
