Hi Simon,
I have tarot 4006 620kv motors fitted, coupled to the platinum pro 30amp escs fixed under the motors. 12" props. Looking for smooth flight (for video) my gains are low just now 125 125 100 125 and 125 on the atti pitch and roll

Simon,
Double check your settings, Info@key-photos is using these settings, (much lower than yours) and he is having luck.
Mine are as follows:
125 / 125 / 120 / 130
140 / 140 /
Also note, mine are still as little "twitchy" as well. I'm going to dial down my Attitude (from 140 to 125) as he has and see where that gets me. Actually, I'm going to use all of his settings and see where that gets me.
As far as your belief the motors have too much power, that is where dialing down the settings are at. Think of it like a race car, sure it has too much power on city streets, so you set a wood block under the throttle, this "limits" the amount of power/thrust the FC will input and the sensitivity.
I experienced too high of a setting when I went to my TBS Disco Pro (From Naza F550) and I almost had an instance of it flipping over as well.
I Firmly, FIRMLY believe the #1 thing you need to do is dial back your settings. I probably won't get to put mine up in the air this evening, but I'll change my settings Saturday (Its friday here in Korea) and report my findings.

edit: lastly, do you have your X/Y axis correct on the GPS? I don't know how critical this is, I've never noticed a difference, but it is worth a shot. Also, is your declination correct for the compass? (research the "DJI Toilet Bowl Effect"). Just other thoughts. I"m 100% sold on the settings at this point. Having experienced it previously on a Quad of my own.
