TBS Crossfire Diversity Nano RX

The TBS CROSSFIRE Diversity Nano Receiver is a compact R/C receiver with 8ch outputs (PPM, SBUS, and CRSF capable), with best-in-industry noise-rejection and record-breaking range capability. It is the only receiver to provide a true dual-input stage, chip-based diversity, with the usual filtering and noise rejection from onboard video systems.

Ever lost a plane and spent hours looking for it? Enter the TBS CROSSFIRE beacon mode. The diversity nano receiver comes with a LiPo battery port where you can connect an optional backup port (1s). It will keep the receiver running for a full day after all onboard electronics are gone. It will be screaming for help by giving you its GPS coordinates, and also blasting out RF beacon signals that will allow you to pinpoint its location even if no GPS was ever on your airplane. The backup battery (1s) will also be charged as soon as you apply power to the rig. 

UPDATE YOUR CROSSFIRE TRANSMITTER TO V2.88 OR ABOVE BEFORE BINDING!
