We recommend using the official release of the TBS Agent software by Team Blacksheep to flash your QQ190 Racing Drone.
We also offer the software as the only official method for flashing the Team Blacksheep Powercube, TBS OSD units such as the Core, Core Pro, and the TBS FPVision board.
Click the link to download from our Google Drive and then be sure to update the software before flashing. The TBS Agent Software for flashing Team Blacksheep Products works on PC only.
