FrSky 2.4GHz L9R 9/12CH S.BUS ACCST Long Range Receiver
FrSky's answer to range anxiety, the FrSky's L9R receiver and can be used in regular PWM mode (9 channels) or SBUS (12 channels). The range reported on this receiver is double that of the other X series FrSky modules, allowing you to go between 3-5km out.
There is no SmartPort on this receiver for voltage telemetry, as pilots who fly out to such ranges usually have an OSD feeding back data from their UAV. The L9R does output RSSI levels so that can be fed into the OSD giving you a reliable signal strength measurements
The unique antennas featured are specifically designed for this receiver to give it such long range.
