FrSky D8R-II PLUS 2.4Ghz 8CH Receiver with Telemetery
FrSKY ACCST technology is proven, approved by many model associations, tested and reviewed as the leading Chinese 2.4Ghz R/C Technology. If you think DSM2 or FASST is the best, think again!
New FrSKY ACCST (Advanced Continuous Channel Shifting Technology) gives you secure radio communicatios in 2.4Ghz band. ACCST 2.4GHz system shifts 80 channels around hundred times per second in the 2.4GHz band. This means that the system is completely resistant to interference in that band.
The Two-way Radio System developed by FrSky provides an additional return link that would be used for monitoring the Rx’s voltage, temperature, location, speed and so on.
Features: Advanced Continuous Channel Shifting Technology (ACCSTis our advanced tecnology it shifts channel hundred times per second and there is no signal conflicts and interruptions) robust frequency agility. Easy to bind and very fast link-up. Excellent reboot time. True Diversity with two antennas. All channels can be programmed with Failsafe, quickly and easily. Quick and extremely stable in performance. Precise and smooth servo response. Extended range (1.5km-2.5km).
Compatibility: Compatible with FrSky two way telemetry modules: DFT, DJT, DHT, DHT-U
Receiver Specification: Operating voltage: 3.5~10.0V Power consumption: 100mA Resolution: 3072 Analog voltage: 0~3.3V Number of channels: 8 Range: 1.5km-2.5km Dimensions: 55 x 25 x 14 mm Weight: 12.4g
You need to use the FRSKY voltage sensor FBVS01. The highest voltage the A1 or A2 port can handle is 3.3 volts. The voltage sensor just lowers the voltage down. If you put more than 3.3 volts in then you chance frying the voltage detection circuit in the receiver.
If you fly FPV, the audible RSSI alert for signal strength is worth it alone. Use the other channels for receiver voltage, main battery pack voltage, your choice... plus one RS232/serial port for realtime downlink to transmitter. Fantastic!

These are just fabulous receivers. Tested my first one out on my Eflight Extra and got a few low signal beeps at the extreme far corners. Landed, rearranged the two antennas, and presto the problem solved. Also tested with several low state receiver batteries and it didn't hesitate to bitch. All this with no programming. I now own 8 of these little guys and real happy with all of them.
