I was torn between the FASST Module and the Spektrum for my 10x. I wound up going for the Spektrum last November because my investigation into the JM912 in the radios forum turned up nothing. I guess it was too new back then. I was really annoyed that it took almost two months to get the Spektrum module. Several phone calls to Horizon finally got an answer. The order was delayed due to problems that produced those horror stories you heard. I placed my order during a major redesign. I was told that there was a major firmware change, as well as elimination of a little cable from the module that needed to be plugged into the Tx. I have had no problems so far. I was steering toward the JM912 because the Futaba receivers are more economical then the JR, but the Spektrum receivers are cost competitive with the Futaba. What finally sold me was that the Spektrum module is made by the manufacturer of the Tx.
