FPV Cruizin! - Homemade 400 Quadcopter

Just some relaxed crusing around with my homemade 400 quad, Really happy with how this thing flies, still getting wobbles at full throttle that I cant seem to tune out, also as you'll see in the video every now and then the yaw seems to jump a little, not sure if this is just down to PID's or maybe motor sync issues as it only seems to happen above 60% throttle most of this video is around the 60% mark as still cant really open it up due to the wobbles, thoughts?
for more pics and specs of the quad.
