Air Speed won't Zero

Hi,

I've got:

APM 2.5 

3dr airspeed sensor

3.x firmware

Can't get the airspeed to zero even when pitot is covered. Tried the preflight calibration button but that had no affect. It fluctuates between 4 and 6. Any ideas how to get AS to show 0 on the flight data display?

Thanks!

Brian

  • Mine bounces between 2 and 3 when on the ground regardless of what steps I take. My understanding of the wiki is this is normal behavior. When I fly it is steady at whatever speed I am flying at. Sorry I can't be of more help.
