I have a Spektrum module for a Futaba 8u or 9c that I will sell you if you want it. I quit using it and switched to Assan and had much better results in a small flying group. I think the Spektrum problems were related to power brown outs some of us had when flying DX6i's and flying for 4 hours on the slope. Never had any trouble with this module. I have since switched to FrSky and have been very happy with it as well. Now flying in conus and many more planes and chances for 2.4 interference. I think the FrSky is every bit as good as the FASST and much better price. If you want that module let me know. We can figure out a price.
