I have an Aerofly Professional Deluxe and can't seem to get a transmitter to work with it. I have one of the cheap esky transmitter type controllers that will work but can't get my Futaba 7C to work. The program finds the interface cable but won't acknowledge the futaba. Since Icarus happened to be right here in fort myers as i found out, i visited them and they tested the cable which was good. They noticed that my transmitter was set on PCM and advised me that it had to be set to PPM in order to work with the sim. I went home, changed the modulation and still, it will not work. Anyone have an idea here before i make another run to Icarus tomorrow? The error states that the interface cable was detected but no transmitter or controller could be found.
