The most advanced and most popular brushless whoop flight controller is now available in Australia.
The 4 gram BetaFPV F4 brushless flight controller contains sheds even more weight with the integrated SPI FrSky receiver, sporting onboard Betaflight OSD and an open UART for Smart Audio.

What is SPI?
Basically, SPI is a communication protocol like UART, a serial communication protocol. A SPI connection requires 4 wires, while an UART connection only uses 2 (TX and RX). However SPI is faster than UART and places less stress on the processor.
Currently the built in Frsky receiver is compatible with Taranis, Taranis Plus, X9E, Horus X12S, XJT Modules with International Firmware (in D8 mode). Pay attention, this is a SPI connection receiver. In Betaflight Configuration, it should be setted as FRSKY_D receiver in SPI RX mode.
- Power the flight controller
- Hold the "bind" button for 2 seconds — the flashing green LED will turn solid
- Put your Taranis in to bind mode (using D8)
- The green LED should now be flashing indicating that binding is now complete.
