I have a problem with my airspeed and ground speed for my plane. Basically in a large circle loiter in one section the air speed drops to 9-10m/s and ground speed drops to 1-2m/s.
It doesnt make sense because i have an air speed sensor enabled
I recently upgraded to an air speed sensor for a wing wing z84. Plane flies create in FBWA and AUTO but it does not seem to control air speed very well. Cruise speed is 10m/s but its flying at least 20m/s. Altitude control seems fine. Wind
I've noticed when in AUTO mode and my RC TX is turned off or goes out of range the throttle % drops to considerably low values. i.e. 15% The plane flies very very slow when this happens (8 m/s).
The APM 2.6 in auto mode cannot seem to get the plane (wing wing z-84) down to the target cruise speed of 12m/s. During missions in still conditions it flies at 15-20m/s. Stall speed is 6-8m/s.
I'm using a 3 cell battery made with NCR18650B cells with PCB protection on my tricopter. My tricopter only draws 3A to hover (~40-50 watts) so I believe these batteries can handle the discharge current required without exploding.
