I didn't know about the wind settings, I thought it was just thermal settings for glider pilots. What version FMS do you use? I have the 2.0 Beta 7 version.

I just ordered a Serial PIC cable from MileHighWings.com. Cost me $20 with shipping. It will let me use the transmitter I already have. I saw the plans for building a Serial PIC cable. While I'm confident I could build one, I wouldn't save a lot of money. I usually prefer to build it myself, but this time, it was easier to part with the $20.
