Hi, I'm pretty new to this forum, and I have a problem with my Q500. I haven't used the Q500 yet because of this beeping issue. I also bought this seconded handed in pretty good condition, with no cracks in the frame too, and never crashed. When I bought this though, it didn't come with the steady grip, camera, and USB programming interface key. When I turn the drone on, the rear light turns green for about a second and starts having a beeping noise, and the light starts flashing red. It will keep beeping like that until I turn it off, I tried searching it up but can't find any results about the situation. I'm going to attach a video so you can see what I'm doing. I also tried calibrating the drone, but when I tap the ST10, nothing happens. I did manage to connect the ST10 to the drone, though. If you look at the video, the drone makes the beeping noise even before I connect it to the ST10. The link for the video is here and the full video is here. Also, any suggestion for where to buy the USB programming interface key is appreciated. As I currently live in Canada, it's a bit hard to get repairs currently.
