Have had about 20 flights, took it to florida -always at my side in a hard shell case-inside case is foam cut outs. Did an upgrade before flight then stick-error, beep beep, couldn’t remedy. Tried everything over last 2 months with no luck. Calibration impossible because left stick is dead. Right stick is fine. Deleted app, reloaded, same problem. New remote $375, not much out there for a fix.
