Team BlackSheep (TBS) Crossfire Nano RX

The TBS Crossfire Nano RX from Team BlackSheep (Singapore) is a small long-range Crossfire receiver on 868 or 915 MHz, built for small FPV drones. It passes the control data on over CRSF, SBUS, PPM or PWM, so it can be connected to flight controllers with different interfaces. Crossfire is the sub-GHz system from TBS, designed for link reliability rather than the shortest reaction time.

It weighs 0.5 g and carries 12 channels. The 40 km range is a manufacturer figure without distinguishing FCC from CE; it describes a best case with clear line of sight and altitude and, without those conditions, is not comparable with other systems. Supply voltage runs from 3.3 to 8.4 V, and the firmware starts at V6.10. Low frequencies penetrate obstacles better than 2.4 GHz, while the packet rate is lower than with ExpressLRS on 2.4 GHz.

The 915 MHz version is the FCC variant; in the EU the 868 MHz band with its own power and duty-cycle limits is the one to use. Equipment may be operated in the EU only in the approved frequency ranges and power levels. In the open category visual line of sight applies, and long ranges are no selection criterion there, but they are for operations in the specific category.

When choosing, firmware upkeep counts: transmitter and receiver need compatible versions, and V6.10 is the lower limit. The receiver has one antenna; the longer 868 MHz antenna should be routed straight and clear of carbon fibre, otherwise range drops. At 0.5 g the solder pads and the antenna connection are the wear points in crashes. Anyone who needs redundancy or diversity chooses the diversity version.
