I do know of the 12 channel Graupner/ Jr radio. I have one at the shop where I work on weekends but the problem for me is that it is 12 channels only when it is in PPM mode. I would never fly a fast or expencive plane or heli without a PCM RX in the model. I know that all of you diehard PPM guys will disagree; but I have my own reasons why I will not fly my jets without PCM RX's that we can agreee to disagree on.
