Last week I received 4S batteries and have been trying to tune the PID's on my Y6 for it. I am hoping some of you who are using 4S batteries can share your params so I can compare. I started with the params file posted on the 3DR site.
I'm having a hard time getting away from a 'twitchy' feel, and also having a weird problem when I'm flying forward my YAW oscillates slightly back and forth (does not happen when i am hovering). if a gust of wind hits the copter, it does not smoothly adjust, but instead twitches a bit before coming stable again. As you can image this makes it impossible to record video (or fly around with confidence)
Any help or input would be greatly appreciated!
Best,
Raph

still not able to get rid of it, here's a video.. you can see it's constantly trying to keep yaw direction with small (and annoying) left/right movements whenever throttle is applied:
what values should I be focusing on? I've tried changing the stabilize yaw value, and the rate yaw P, and they seem to have no effect at all while I was hovering - I used the max/min value range listed in the wiki. I'm using the chan 6 nob in flight tuning method. so frustrating :|

So Ralph did you buy a third set of ESCs? I think I remember your 2nd set were 3S only.
