I received a replacement V6.1 board from GetFPV over the weekend. I have installed it on my 4 inch 190g, 33 minute flight time build. OSD and everything else is now working great. When all is said and done, the only new feature over the V6 for ardupilot seems to be current readings for ESCs which supply the analog signal but don’t track current via telemetry. It’s too bad we didn’t get an extra usable full serial port, but at least we didn’t loose one. Luckily, it turns out that the hwdef already included the current pin even though the V6 didn’t connect it.
I’ve posted details of my build here:
