Flow and Rangefinder problems

Hi @ all,

I’m new to all of this and i’m facing big problems to setup a PixHawk 2.1 with Pixflow and a SF11 rangefinder.
I did all the installation instructions for flow and rangefinder but when i take off in loiter the copter does not
fly stable. i hope someone of you can help me with this when i’m posting a log file.

Thanks in advance…35 01.01.2000 01-24-06.bin (1.8 MB)
