For a while now, over the last few firmware updates (I'm with an A2s), when I start a flight I have pitch and yaw but NO roll control. To address it I would attempt restart, recalibrate sticks, etc. all to no avail. Finally, somehow I figured out that if I simply move the C-N-S switch from cine (what I use 99.9) to normal or sport and back to cine, I regain roll control. This happens every time I go to fly. This post is as much about looking for a cause and fix as it is to perhaps help anyone else who might experience this phenomena. It's an easy "fix" when beginning a flight, but obviously it's a malfunction. Any
