I have my MinimOSD flashed to 2.0 firmware and it is working, I can see characters. (not so clearly but i've reflashed firmware+charset multiple times so suspect either VTX or cam or goggles here)
With a friend's help, worked my way through the PPM encoder firmware update and got the throttle failsafe all sorted. When I turn my radio off, the throttle drops to 924 which is below my FS cut.
