Drone starts to go up in position mode with px4flow

🧪 Flight Testing & Log Analysis

Hi guys,

I’m trying to get my drone (a quadcopter with px4 equipped with a px4flow) hovering at a stable height in position mode however after a couple of seconds after the take off, it starts to go up and it does not respond to any command (lower the throttle does nothing). I Have the same behavior with the altitude mode.

log1
log2

I had upload 2 different logs because in log1 I’d changed some parameters.
Have you guys any advice? I’m new to this world.

Thank you in advance

Not sure if you still have this issue, but your altitude source is very important.
