Comparison between G473 and F411

Say goodbye to limitations and take advantage of the advanced technology of the G473 flight controller, which provides an unparalleled flight experience. The Air Brushless Flight Controller features a CPU clock speed of up to 168 MHz and 4 additional serial ports, ensuring lightning-fast response times and advanced computing performance. It is ideal for demanding flight, taking your flying experience to the next level and demonstrating exceptional performance, surpassing the capabilities of 1S flight controllers on the market.

Serial ELRS 2.4G RX uses Crossfire protocol (CRSF protocol) to ensure communication between the receiver and the flight controller board. Therefore, Serial ELRS 2.4G RX can be upgraded to ELRS V3.0 without the need to reflash the Betaflight flight controller firmware. Enter pairing mode by turning the power on/off three times.

1. Connect and disconnect the flight controller three times;
2. Make sure the RX LED is blinking quickly in double flashes – this means the receiver is in pairing mode;
3. Make sure that the RF TX module or radio transmitter has entered pairing mode and sent a pairing pulse;
4. If the receiver lights up steadily, it is paired.

The Serial ELRS 2.4G RX can be updated using Wi-Fi or Betaflight serial passthrough. Here is how to update the Serial ELRS 2.4G RX firmware via passthrough:

1. Connect the flight controller to the computer, but DO NOT connect to the Betaflight configurator;
2. Select the target "BETAFPV 2.4GHz AIO RX";
3. Overwrite using the BetaflightPassthrough option in the ExpressLRS Configurator.

Bluejay ESC software

Using the BB51 ESC solution, the Air Brushless flight controller is based on the A_X_5_96KHz_V0.19.hex file for the BB51 Bluejay hardware platform. It supports D-shot300, D-shot600, and even RPM filtering in Betaflight. It also offers 24kHz, 48kHz, and 96kHz fixed PWM frequency options, as well as the ability to use custom start-up melodies.
