Now it appears from the GoPro footage that the control wheel was deflected to the right which would cause right aileron up, maybe in an attempt to counter an uncommanded left aileron up condition? Both ailerons up, drag from an unfeathered prop, loss of power on the left hand side. I guess if all that was so the only way was down?
When the cable is severed or stretched, both ailerons will be up. Of course that will be a lot of additional drag.
