I can't use my Hitec flash 5 on my computer to fly with fms.
The computer doesn't recognise anything. I use a simple serial port interface and win98.
I followed the instructions on :

Nothing, I tried with the cristal removed....nothing.

I don't know what is PCM and PPM mode an don't know if my radio is cabable of switching modes. (fms uses only PPM mode)
