Does anybody know where I can find a wiring blue print for preferably a USB cable, but a serial cable will do, for a tx to computer setup. I have already made a training cable for my Futaba, I didn't feel like spending $16.00 to $18.00 for one thru TH's so made my own for just under $5.00. I figure I can save myself some more money and do the same with a sim flight cable also, just need to know what I need and how to wire it. I tried a search with no luck on here, so thought someone might have a link or know where to find it here. Any help would be greatly appreciated.

Thanks, Jim Starbuck
