using FMS saves 100's on repair, and gives opportunity to fly and feel loads of different models, not just one you have :) This cable is on sale here: search.ebay. I had no choice but to get my transmitter working with FMS so i've found schematics and software for cable wich is connects to MICROPHONE JACK and there is no needs to setting it up it JUST WORKS! I've built my own cable and the only thing i had to do is connect cable and calibrate controller the same way as if it was joystick. After days of surfing internet 100's sites & forums, found out that most walkera transmitters are PCM modulation but USB interface ONLY works with PPM transmitters. Hi everyone! Got USB cable interface for FREE FMS RC FLIGHT SIMULATOR of eBay, was asured by seller that it gonna work with my Walkera WK-0701 transmitter, but it did not, and even more i could not find drivers or software to get it working, as it turned out it was impossible to setup cable which is 'VERY EASY TO SETUP'.
