Analogue RSSI on ADC port on a Cube

hi all sorry to ask here after some days i am trying to inject analogue rssi into ADC on a Cube running ArduPlane V3.9.8 is there an issue with ArduPlane ?

All good it was a mission planner issue
all i did is un ticked rxrssi in the user items and then re ticked started working :roll_eyes:
