The process of downloading the Walkera QR-X350 PRO Drone Firmware 1.7 driver should begin automatically after a few seconds. If this does not occur, click on one of the links below (we recommend downloading the Walkera QR-X350 PRO Drone Firmware 1.7 driver from the primary server - this is the manufacturer’s Walkera official website). If the download still fails to run, check whether your anti-virus software is not blocking the connection to the manufacturer server of the Walkera QR-X350 PRO Drone Firmware 1.7 diver.
