The FrSky receiver X8R supports 8 standard servo outputs

FrSky receiver X8R Description

The FrSky receiver X8R is in a Smaller package then previous 8 channel receivers, but has so much more capability. The new SmartPort supports the new hub-less sensors as well as the older hub analog sensors.The X8R supports 8 standard servo outputs, and you can access all 16 channels by using the Sbus line with Sbus supported servos or use a FrSky S.BUS Decoder for the full 16 channels. Or you can use 2 X8R receivers in combination and the channels will sync 1-8 on the first and 9-16 on the second.The FrSky receiver X8 protocol is also backward compatible! In D8 mode it work with the DHT, DJT, DFT and DHT-U transmitter modules.

FrSky receiver X8R Features:

More number of channels: 1~8ch from conventional channel outputs, 1~16ch from SBUS port,or combine two X8R to become a 16 channels receiver.
Parallel two X8R to become a 16 channel receiver.
With RSSI PWM output (0~3.3V)
SmartPort enabled, realizing two-way full duplex transmission.

FrSky receiver X8R Specifications:

Number of Channels: 16
Dimension: 46.5mm x 27mm x 14.4mm (1.83" x 1.06" x .56")
Weight: 16.8g (.59 oz)
Operating VoltageRange: 4V-10.0V
Operating Current: 100mA@5V 
Operating Range: >1.5km (FullRange)
RSSI output: analog voltage output (0~3.3V)

FrSky receiver X8R Compatibility:

All 16 channels requires the FrSky Taranis, or the XJT module bound in D16 mode.
For 8 channels in D8 Mode you can use the FrSky Taranis or XJT, DJT, DFT, DHT and DHT-U modules.
