Comparison Between G473 and F411
Say goodbye to limitations and embrace the cutting-edge technology of the G473 flight controller for an unparalleled flight experience. Air Brushless Flight Controller features up to 168MHz superior CPU Clock Speed and 4 richer serial ports, enabling lightning-fast response times and advanced computing power, making it ideal for demanding flight, which takes your flying experience to the next level and demonstrates outstanding performance, surpassing all 1S FC options available on the market at present.
5 IN 1
Choose this higher integration Air Brushless Flight Controller, for an ultra-light 1S whoop installation, tailored to meet the needs of discerning pilots. It is default integrated onboard 25-400mW VTX, the 5IN1 Version that integrates FC+ESC+OSD+VTX+RX goes a step further by integrating the Serial ELRS 2.4G RX, streamlining installation to save space and reduce weight, and enhancing convenience for VTX and FC adjustments.
Serial ELRS 2.4G RX
Serial ELRS 2.4G RX uses the Crossfire serial protocol (CRSF protocol) to communicate between the receiver and the flight controller board. So the Serial ELRS 2.4G RX is available to support upgrading to ELRS V3.0 with no need to flash Betaflight flight controller firmware. Enter binding status by power on/off three times.
- Plugin and unplug the flight controller three times;
- Make sure the RX LED is doing a quick double blink, which indicates the receiver is in bind mode;
- Make sure the RF TX module or radio transmitter enters binding status, which sends out a binding pulse;
- If the receiver has a solid light, it's bound.
The Serial ELRS 2.4G RX can be updated via Wi-Fi or Betaflight serial passthrough. Here is the way to update the Serial ELRS 2.4G RX firmware through passthrough.
- Plug in your FC to your computer, but do NOT connect to betaflight configurator;
- Choose target "BETAFPV 2.4GHz AIO RX";
- Flash using the BetaflightPassthrough option in ExpressLRS Configurator.

Betaflight Firmware and CLI
Betaflight official developers recommend using version 42688 of the gyroscope, and many issues with ICM42688 have been fixed in version 4.5.0. Please learn more from version 4.5.0.
Bluejay ESC Firmware
With BB51 ESC solution, Air Brushless Flight Controller is based on A_X_5_96KHz_V0.19.hex for BB51 Bluejay hardware, it supports D-shot300, D-shot600, and even RPM filtering in Betaflight, offers 24KHz, 48KHz, and 96KHz fixed PWM frequency for options, and custom start-up melodies.
DO NOT flash the firmware with a shorter interval, otherwise, there will be a certain chance of stalling and burning the flight controller.
Connecting External RX/VTX
Please note that UART2 has connected to the VTX by default. This FC reserves 3 complete full-featured serial ports that can be used for external CRSF/SBUS receivers, GPS, HD VTX, or other serial devices. You can refer to the below pictures.
Attention
- VTX Power: Higher VTX power consumes more energy and generates more heat, reducing flight time. For better flight time in indoor scenarios, use 25~100mW power.
- Motor Wiring: Only soldering is supported for motor wiring on the flight control. Avoid terminal plugging.
- VTX Antenna: Connect and install the image transmission antenna before powering on the flight control. Alternatively, set transmission power to 0 to avoid burnout.
