FrSky passthrough and Yaapu works fine (Copter 4.0.5 Stable)
Frsky Smartport Telemetry,
I use receiver X8R and Smart Port Connected Ground and Signal to Inverter (no 5v red cable)
Then from Inverter to TX4,RX4,5V&G on the F405-STD
SERIAL2_OPTIONS 0 (Its several options available now)
Max3232_3.3v_diode F405-STD Yaapu working, 5v from FC onlyNo 5V from receiver

I ended up creating a new inverter with cabling to suit the pins on F405-STD.
