Hi guys,
i have an apm on my quad, which works great in general (this is not my first multi or APM) and i have an issue with alt hold...
I have set my midpoint, hovers at mid stick, but all the time in alt hold or loiter it will ascend slowly or descend slowly until i make a correction. Not sure if the APM is fualty as i did not have this problem before on my previous quads. I did squeeze a bit of foam into the case, maybe too much? before i have had other issues with alt hold regarding pulsing etc, but never this problem. Other issues i have successfully tuned out, the apm is in a case, on a vibration mount, protected from sunlight.
If i send it up to 20M, then engage loiter or alt hold, it will either rise slowly or descend slowly, until i push the throttle out of the deadband. My pixhawk is just nailed on in alt hold and my previous APMs and crius have been ok.
Does anyone have any ideas??
