Happymodel ELRS X2 AIO 2-4S Flight controller built-in SPI 2.4G ELRS and 12A ESC 25.5mmx25.5mm for Mobula7 HDZERO


The ELRS X2 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.

Bind procedure:

  1. Connect ELRS X2 flight controller with computer by Plug USB. Running Betaflight configurator and then move on Receiver tab then hit “Bind Receiver”. The Red LED on the flight controller start blinking fast, it means onboard SPI ELRS receiver is in bind mode.

  2. Turn on your radio transmitter and running ELRS.LUA v2 version, scroll down the menu and hit [Bind]. The red LED on the flight controller would get solid first and then start to blinking slowly. It means bind successfully. Re-connect the USB and then you will find link was established.
