After work today I came home to three freshly charged batteries and my CX2 waiting for me. This is the first time this has ever happened to me, but as I would fly forward the nose would stay straight but the entire bird would strafe left as it moved forward. I went through the usual: blade damage, warped blades, balance, and couldn't find anything unusual. Checked for friction in the drives, all clear there. Can't think of what else it could be. Anyone have this happen to them? Fixes???
