I recently used a couple of my QR X 350 Pros with mission planner software. Now neither one will bind. The left green light blinks but that is it. Neither one will aquire sats or bind. Is there something I can do to return them to out of the box st Iate ? I tried reflashing the v 1.7 firmware with no results. I really screwed up using the mission planner on them but was told they were compatible.
