Losing Altitude in Loiter (ArduCopter)

Hi everyone,

I am an APM2.6 with FW 3.0.1 on my quad with T-Motor MT3520-11 Motors and 13 x 4.7 APC props.

When in Loiter mode and no operator instructions my quad sits perfectly still however as soon as I fly into the wind I lose altitude (2m loss over about 20 meters). The wind speed is around 3 meters per second. Flying with the wind causes no change in altitude.

 

What can I adjust in order to maintain altitude while flying into the wind? I would like to try and avoid having to give throttle instructions while flying horizontally in loiter mode.

 

Any suggestions would be greatly appreciated!

  • I have same problem on APM2.5 with external compass and 3.2rc-2 firmware. It was same behavior before, from fw 3.1.2 which is my first fw ever tried. In forward flight hexacopter looses altitude in loiter, alt-hold and now in hybrid mode.

    Is there some setting which can help or it is vibrations problem?
