I recived My goggle2 from hobbygaga. Perfect for delivery an package. The video reciver is ok with my tali H500, the output video is ok. The input video not working. The head tracking is not working. I follow the tutoriel to link the goggle with the reciver but it's not working. There is no link cable to charge the battery
