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?

This is a known problem. Even some of the older Futaba 9 channel PCM1024 RX's won't work. Futaba service centers can take care of that for you - usually at no labour charge. Why this happens, I don't know. I have long ago given up mixing radio gear. Servos are OK, but not RX's.

Some of mine did this and Futaba took care of them for me. The 9Z rocks!

Check the futaba-rc website, there is some more info on this.

Safe Flying!

Futaba can guarantee only that their receivers will work with all of their other types of equipment. All current Futaba receivers will work with all current Futaba transmitters, given that the same channel and modulation type are used on both units. Futaba cannot assure you than other manufacturer's equipment is compatible with their equipment. That would be up to those manufacturers.

The synthesized RF module used in the 9Z transmitter does have a slight difference in its signal that some non-Futaba receivers cannot properly decode. This is not a problem with any Futaba receiver.
