Synching Problems? Teaching ESC alltogether?

Hi all.

My SkyHero Y6 with APM 2.5 and the latest stable FW makes strange "knocking" sounds when in idle. There are none of these sounds when working at higher throttle.

I use the Tiger Motors MT2814-11 710 kv and Yuki cayenne 40A Opto ESC (simonK).

The video is here:

Synching problem?

Has anybody heard that before? Could this be an issue of the "teaching all ESC at once" method?

Regards 

John

  • Hi. This definitely was an issue with the "teaching of all esc at once".

    After a new teaching procedure of every esc individually the problem is gone.

    • Hi,

      I have observed similar sounds (not continuous) not only at idle but also in mid flight when I tried to pitch and roll the copter fast. I have followed all-at-once esc calibration method. I think this is due to simonk firmware. Never tried normal esc with apm.

      • Hi,
        Did you encounter any problems Other than the sounds? Actually my sounds are still there and I haven't flown it yet. Did yours ever fail in midflight or did it fly safely?
