Have had great results so far using the Transvideo Virtual Horizon 3 bluetooth external level attached to my XCS Monitor bracket, and wanted to share that I am stocking power cables for this little module. I know they can be tricky to find. Am currently powering/charging it off my 4-Pin VID/PWR port on the lower stage. If interested, you can order this cable here:
If anyone has questions about the module before buying, or wants to see a video of it in action please feel free to reach out!
