HappyModel 1S F4 AIO Toothpick/Whoop Flight Controller W/ 5A 8bit 4in1 ESC & 200mW VTX – ELRS 2.4GHz SPI

The world’s first AIO 5in1 F4 flight controller with an 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 what all Race/Freestyle pilots need. It is suitable for whoop Race or Toothpick Freestyle, and can also be used in the 1S ultra-lightweight Nano Long Range platform.
