Are you looking to buy a HappyModel ELRSF4 2G4 V3.3 AIO 5in1 Flight controller built-in SPI 2.4GHz ELRS RX in Australia?
The world’s first AIO 5in1 F4 flight controller with integrated SPI 2.4GHz ExpressLRS receiver has been launched. The flight controller integrates SPI controlled 2.4GHz ExpressLRS receiver, Dshot protocol 4-in-1 ESC, 5.8GHz 40ch video transmitter and Betaflight OSD. Ultra-small size and ultra-stable remote control range can improve the range of the original SPI receiver. And because the 2.4GHz ExpressLRS receiver is equipped with the SX1280 radio frequency chip with high sensitivity, high packet rate and low latency, this flight controller is the one that all Race/Freestyle pilots needed. It is suitable for use in Tiny whoop Race or Toothpick Freestyle, and can also be used in 1S ultra-lightweight Nano Long Range platform.
