I flew for the first time with flight controller of matek f405 wing in AR wing,i didn’t use airspeed sensor ,so i have to pay much attention to the ground speed,But something magical happened.
I found the plane have airspeed and wind value in the OSD after the plane in the air .I have know the FC will estimate an airspeed if without airspeed sensor.By comparing with another aircraft equipped with airspeed sensor, I found that the airspeed estimated by f405 wing is quite accurate.
One thing I’m curious about is how flight controller estimates the airspeed?
What do we need to pay attention to when there is no airspeed sensor ?
I don’t know if I believe the airspeed estimated.?
