Unstable hexacopter with new ESCs

[kjetilpa]

I am using a Tarot T960 with Tmotors 4014-9 400 and a NAZA-M V2 flight controller. Until recently this setup was rock solid and a dream to fly.

But after 20-30 flights with my new motors I experienced some problems which I think is caused by timing issues (motors - esc). See this post:

So I switched to 6 new ESCs from Hobbyking:

(Se image for ESC settings)

Now the copter feels unstable when in the air. See the video.

Can this be caused by incopatible ESCs, wrong ESC settings - or can it be something else??

Not certain but I thought I heard a lot of motor "ringing" in that video. If that was the case there are timing issues.

Hi, not an expert but with higher pol motors you should buy a matching set of ESC's why did you not buy the matching T-Motor ESC's that work with your motor?
