Note: The Happymodel ELRS X1 AIO 4in1 Flight controller is no longer available. Please order the upgraded X12 ELRS V2.0 The ELRS X1 flight controller comes with integrated SPI 2.4GHz ExpressLRS receiver and 12A Blheli_s ESC which could support 2-4s. Bigger Mosfet could support high to 12A currents would be better for 2-4S toothpick drone or long range FPV drone. 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. The flight controller reserved 6pin SH1.0 plug for CaddxFPV Vista HD VTX and 5pin SH1.0 plug for analog VTX. Notes: ELRS X1 flight controller will work with the ELRS 2.4Ghz TX module which was updated V1.0.0 or latest version firmware. So no need to flash old RC3 version firmware for the TX module.

Please make sure that the port driver of the flight controller is correctly installed on the computer, then open Betaflight Configurator(Latest version) to connect, enter to the "receiver" interface, and then click "Bind Receiver", the red LED at the bottom of the flight controller will flash quickly, which means that the SPI ELRS receiver enters the bind mode. There is another way to make the receiver enter the bind mode: after connecting to the Betaflight configurator, move to the CLI interface and enter "bind_rx" in the command line. After correctly connecting the 2.4G ELRS TX module to your Opentx radio transmitter, copy the latest version of ELRS.LUA file to the SD card in the remote controller. The directory is "SD Card/Scripts/tools", Then run ELRS.LUA and upgrade thefirmwareto latest version and click “bind” with the SPI ELRS receiver. Please make sure the packet rate is the same between the SPI ELRS Receiver and your ELRS TX module. Change packet rate for the SPI Receiver command in the CLI tabSet expresslrs_rate_index = 3Allowed range: 0 - 4Default value: 00=500Hz,1=250Hz,2=150Hz,3=50Hz,4=25Hz After the binding is successful, the Red LED at the bottom of the flight controller will getting to be solid, and the telemetry can be received at the same time. The meaning of the LED status of the SPI receiver: the LED is getting to be solid, indicating that the bind is successful or the connection and communication is normal, the LED flashing quickly indicates that the receiver is in binding mode, and the LED flashing slowly indicates that the there is no signal received from the radio controller.
