I have just purchased the 9ZWC2 radio, but was shocked when it did not work with all my existing recievers. I have 4 other Futaba radios, from the 7UA up to the 9CAP, and they all work with all my recievers. So why does the 9Z with its synt module not work with them all? The recievers in question are the GWS R6N, FMA 2000B, and the Hitec RCD 3200. The servos just chatter and some go hard over. The thing that realy concerns me is the RCD 3200, as I have several of these. All work except one. I am not sure what to trust, and I do not want to risk a good plane on a flaky system. All but 1 of my recievers are PPM and on the same channel. I only have 1 Futaba PCM which worksjust fine. Has anybody been down this road?
