Strange behavior with small quad

[Yups]

Hello guys!

Finally my AQ flies, not perfect but i am satisfied

... but i have a strange behavior.

Watch this video, please:


(i am a new user, so i cannot paste full links)

I decreased Nav alt speed i to 1.5 but i have still this oszilation. Thats not my main problem. The worst thing is the peeping sound of the motors. The sound disappears when switching to normal mode with full throttle while holding the quad in my hands. Any Ideas?

Yes, full throttle: With full throttle in manual mode, the quad drifts away, turns 180° top facing to the ground and kisses the earth (or snow).

Hi Yannick, welcome to the forums!

Before tuning auto modes, how does it do in manual? Does it have a hard time keeping a steady altitude?

Cheers,

Welcome Yannick!
I've edited your post, so the video shows up.
As Max already mentioned you should tune the PIDs for stability. If it flies good in manual mode, take the next step and tune alt_hold.

Hello!
Thanks max

Sorry for my late replay, but we had bad weather here in the north of Germany.

In Manual Mode it flies good, except of this vibrating and peeping. I haven't had it before with Mikrokopter and Naze32 control boards.
The quad does pos/alt hold immediately! Even while the wind blows very strong outside ... with the seen climbing up and down by 10cm.

My bigger problem is this damn peeping and vibrating.
