Ok. After about 20 mins of flight time and 3 sets of lipos drained. I've got what looks to be a stable 16lb octo with plenty of power to spare.

Again, a huge thank you to eveyone who took the time to help me. This is a great community. I would have been dead in the water without you guys.
I ended up lowering a lot of values by a significant amount. Have a look. Am I in danger of being too low on any of these values? What do you think? The low values seemed to snuff out any remaining osculations.
The throttle still is a bit jumpy, but I can definitely learn to fly like this I think.
One thing which is not quite there yet is gps. Gps hold was working very nicely for not having done any tuning, but moving the copter with pitch and roll was very awkward and clumsy. When I'd give it input, the copter would almost lunge in the direction, then stop every few feet abruptly and swing like a pendulum back and forth and then begin to lung in that direction again. Any advice for me to help fix that? (the video above is manual mode only)
Also, is there a way to set a flight mode that is altitude hold only without gps hold? kind of like attitude mode on dji?
I suppose I could alway unplug my gps but I would love to just have a switch. Any advice would be greatly appreciated.
