Hello All,
Ive recently built a DJI S1000 with the new Pixhawk 2 and Here GPS. I was initially impressed with the results compared to my previous S1000 builds using the original Pixhawk. It seemed to be less finicky to setup and provided decent results with stock parameters.
Today, I took it out for an attuning session. It took 15 minutes to complete the tuning in all axes. The wind was almost perfectly calm. After the tuning completed, I swapped to a fresh battery pack and did a test flight in loiter and auto modes. The copter seemed to twitch and drift the same as it did before the tune. The yaw control became quite touchy as well. Nothing super scary, but I need this copter to be as stable as possible. I've attached logs for each of the flights I did today. I'd appreciate any input anyone has on tuning a large copter like this for optimum stability.

Thanks,
