The digital high accuracy airspeed meter of Arkbird 2.0, can calculate the relative speed between the plane and air, which is different from GPS ground speed. As the air speed is a necessary condition for generation of lift force. Insufficient airspeed may cause stall. The airspeed meter collects the speed in front of the plane. As to flying in windy days or when flight is heavy-loaded, it will increase throttle when flying upwind and decrease when flying downwind.
Extension 3P wire can be used. Do not make the orifice get close to the motor so as to avoid airflow interference. After power on, it will be calibrated automatically within 10 seconds. During this period, do not touch the orifice.
