Thanks for all the responses! I still haven't been able to get the sim cord to work with FMS! Two questions:
now if you are useing a realflight sim cable the 4yf MUST be turned on (not sure about other sim cables but try turning it on anyways)
Is 4yf a setting on RealFlight or on the tx? I am using FMS so if it's a setting in RealFlight I might be out of luck...
OK, turns out I don't have FMS on my PC anylonger, but the USB to Futaba TX calibration program was.
Where can I get th e USB to Futaba TX calibration program?
Thanks again!!!!
