The FrSky X8R receiver features 16 channels (8 normal PWM outputs and all 16 channels on the dedicated Sbus output).
A common question we get is how do you get all 16 channels out of the X8R? Well, FrSky has given you options. You can use the Sbus line to access all 16 channels. Using something like the FrSky Sbus Decoder, you can convert the digital Sbus signal to normal servo outputs. You can connect Sbus servos directly to the Sbus line. Another option is that you can combine 2 X8Rs and output channels 1-8 on the first receiver, and output 9-16 on the second receiver.
But that isn't all the X8R can do. It can also work in "D8 Mode to work with the DHT, DJT, DFT and DHT-U transmitter modules. In this mode you have 8 channels. (Note, for this to work you will need to flash FrSky's firmware back onto this receiver, we now supply them with UNI-RX. We can do this flashing for you at the time of purchase.
You are probably wondering about the new antennas on the X8R. FrSky refers to these as PCB antennas and report up to a 20% range increase over the standard antennas. The PCB antenna does take up a bit of space, for this reason, you can swap to any FrSky receiver antenna to meet your needs.
Dimension: 46.5mm x 27mm x 14.4mm (1.83" x 1.06" x .56")
Weight: 16.8g (.59 oz)
Operating Voltage Range: 4V-10.0V
Operating Current: 100mA@5V

All 16 channels requires the FrSky ACCST radios, or the XJT, XHT modules.
For 8 channels in D8 Mode you can use the FrSky XJT, DJT, DFT, DHT and DHT-U modules.
