uavpilotjoe, According to what I read over at the ArduCopter site and from personal experience (IMHO) your craft needs to be a few meters up to escape the ground effect from the props downward wash for best tuning. I had a lot of trouble tuning my APM2 until I started flying 10 to 20' high. It seemed to just fall into place then. Problems I thought I needed to tune out were actually ground effect. This also applies to a lesser degree (less sensors) to anyone who is trying to tune the KK2 board as well.

I had a hell of a time tuning in the garage, but when I stepped out in the green: WOW ! much more stable.
