You may recall I bricked my Q500 4k when the firmware update stopped in the middle. I sent it into Yuneec, California, and about a month later, I received it back. When I start up the Q500, I get a blinking blue light. Ive tried several charged batteries, but get the same light. The ST10 also shows no voltage or elevation info from the Q500. Any idea of what I might try? As I write this, I may check the white connector is plugged in correctly, but their notes say they flew it before sending back.
