Hi bdmodels,
Sorry that you got off on the wrong foot. If you go to the website, you will see that it clearly says PCM 1024. With that the G3 mode is not an option and with Futaba there are 8 proportional and one switch channel available. You have bought a dual synthesized receiver with an integrated power module and 6 regulators that two are used to control the receivers and the other 4 are used for the servos which you can program all the 20 servo outlets the way you need them.
This often enables you to reduce the amount of needed channels. In addition you can use the sequencing and substitute more channels. You also have programming abilities with your transmitter that you don't have with some of the other transmitters.
The programming should actually work with Windows Vista. We had made that adaptation on the last software upgrade. The transfer error comes from not having the correct com port connected at the top of the program window. When you are connected and you get the error at the right bottom of the field, try the different ports available under the drop down. If that does not work, then you might have to do an install of the USB-port for the Weatronic unit.
Usually Windows will detect the new software when you connect the computer to the receiver. It will prompt you for either the CD or alternate path to look up the place where the USB-driver is located on your hard drive. If you have an automatic install, you will find the files in the following place on your hard drive: C:\Program Files\Weatronic\Dual Receiver Tools\USB_Driver . Use this for the recognition and installation and it should do the installation and you should be able to read or transfer the programs from and to the dual receiver.
If you have any further problems, please don't hesitate to email me directly or go through this forum. I will answer you as soon s possible.

Thanks,

Gerhard
