AC3.2.1 APM 2.5 Throttle pulsates in Loiter

Hi.

I have a problem after updating AC to 3.2.1 from 3.1.5.

When in Loiter, the the speed of the motors rev up and down/pulsate quite rapidly. This was working fine when I was using previous versions of arducopter.

I have downloaded the logs, and have looked into accX, accY and accZ. These seems to be inside the range specified in the wiki at arducopter. (Log_vibrations.bin)

Please have a look at the Log.bin, and note the difference between ThrIn and ThrOut when I'm in Loiter mode.

 

Anyone having any idea what the problem may be?

  • I have now made a video showing the behavior in Althold, Stabilize and Loiter.

    To me the barometer values looks ok, so I really don't know what is going on..

    Please have a look at my video here.

      • No I havent tried that yet. If I do I loose the scaling on RSSI voltage. I currently use FrSky receiver, and it gives out 0-3.3V, and not 0-5V wich is the default in 3.1.5.
