I have just started to make FMS parallel interface cables for JR radio's as I have been in the same position as many people on this bulletin board. Yes FMS is a great program but not so good if you can't connect your transmitter to it! I am an electronic engineer by trade, and my design is modified from several available designs and works well. If anyone is interested I am selling them for £15 all in including p+p (UK) or US25$ rest of world which covers the parts and my time. I am also working on Futaba and serial versions of both. Drop me an email if interested. I accept cash, cheque or PayPal.
