Happymodel CrazyF411 ELRS AIO 4in1 Flight controller
This is the HappyModel CrazyF411 ELRS flight controller comes with integrated UART 2.4GHz ExpressLRS receiver and 20A BLHeli_S ESC(Bluejay firmware pre-installed)
Larger Mosfet would suite 2-4S toothpicks and long range FPV setup’s.
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 built-in ELRS receiver is designed to act like a serial based receiver, it uses a UART to communicate with the MCU, can be updated via betaflight pass-through or WIFI.
The default firmware is ELRS V3.0.1. This flight controller would be used for Crux35 to instead ELRS X1 flight controller.

- Supply power to the flight controller by plug USB, wait until the green LED on the FC is off, immediately turn off the power, and then repeat again the above steps. When the FC is powered on for the third time, the green LED light will start to double-flash, which means that the RX enters the binding mode
- Please make sure your ExpressLRS tx module firmware is v3.x.x. And go to ExpressLRS.lua from “TOOLS” menu of your radio transmitter. Then hit [Bind] to binding with the onboard ExpressLRS receiver. The green LED should blinking slowly first then turn to solid, that means binding was successfully. If the green led still keep double flash after binding ,please change Model Match tab value from “off” to “on” or from “on” to “off”
Receiver LED status meanings
Green LED solid means bind successful or RC link established; Green LED double-flash means get into bind mode; Green LED flash slowly means no RC signal input from TX module; Green LED continuous flash fast means ExpressLRS wifi enabled.
No RC Input
