Where does airspeed indicator come alive?

I have been working on taxiing my recently purchased Model 4 before i actually fly it. I noticed that the airspeed indicator does not seem to work at taxi speeds. I did some testing on it, and it seems to operate fine putting gentle wind into it - but not at taxi. I am wondering if maybe I have not taxied fast enough yet. I have taxied fast enough to raise the tail wheel, but suspect I am only doing about 15 to 20 MPH. Does anyone know if there is a speed at which the analog airspeed indicator comes alive?

I just looked at videos of my Avid and Kitfox 4 and the ASI seems to start to move as soon as I go to full power. JImChuk

so basically once you start to accelerate but not during normal taxi?

Guess I'll have to look next time I take the plane out. Here is a video from late last fall. JImChuk

Nice panel, nice airstrip, nice plane! When you do the turn around, the airspeed does not move until your take-off acceleration. So maybe mine is fine. I will try to get closer to take off and see what happens. Thanks, I appreciate the input.

Roy, just a word of caution with this kind of high speed testing, -be prepared to go airborne! More than a few guys have wrecked airplanes during high speed taxi testing , when the aircraft departs mother earth and indecision results. Bruce N199CL
