John I have this issue too. I have my axis set to "Send Direct to FSUIPC Calibration" and have TransmitClientEvent failures in the log with disconnects.
I have the same issue. I have only tried with the TBM 930. I sat on the ramp for about 20 minutes setting up FSUIPC. Shortly after I got airborne the sim stopped seeing input from FSUIPC. John, I'll try that exe today. Thank you.
