I'm noticing quite a bit of oscillation in descent, wasn't bad in the video but seems to be worse every time I fly? Any ideas?

My WKM quad started doing the same thing a couple weeks ago, turned out to be a loose connection between the ESC and one of the motors. Fixed that and it's been fine since.

Any reason why you upgraded to 30A ESC's? Are the stock 10A ones compatable with WKM?

The stock esc's don't work with the wkm. I think the wobble is because of me playing with the cg settings, trying to get wobble-free flight. That Z axis is a bugger to try to guess!

The wobbly descent might also be descending too quickly. My draganflyer did that, because of the turbulence it creates. It's not that bad with the hexa.

 

[badbill]

Nah. I got it quite a bit better today by adjusting the cg settings. The Z settings are pretty much a guess.
