Hello fellow pilots,
A couple days ago I was flying my quadcopter running on apm 2.6, wich was working fine.
Stab, Althold, Loiter and Auto mode worked flawlessly.
Until yesterday, when I switched my flightmode to Althold or Loiter, my copter accelerated to the sky.
Quickly I switched back to stabilize to get control.
From my experience with apm I immediately thought it would be a badly covered barometer.
I removed the cotton ball, wich was covering the barometer and replaced it with some foam (same foam as inside pelican cases).
After that I took my lovely quad outside to test Althold and Loiter, still the same :(
During the flying in althold and loiter my throttle was at ~50%, my osd and telemetry doesn't show inaccurate altitude readings.
Also my Pilot maximum vertical speed always changes itself to this value, I can't change it neither via telemetry connection nor with usb connection. Could this be the source of evil in this case?
So i'm lost, I don't know what other things I could check.
I have attached my tlog of this evening where you can see the sudden gain in altitude like at 21:14:46.
I would be incredibly thankful with any help.
