I just got the opportunity to test the final version of this product and there is some IMPORTANT INFORMATION that you must know. Firstly, we have tested and confirmed that this VTX overtransmits on some channels. Others have recognized this and therefore it might not be legal at some big races. I do not recommend this flight controller for race builds. Secondly, this flight controller does not always come with an adapter. Ours now DO come with adapters, but don’t expect this to be the case everywhere else until all old stock is flushed out.
Now for the initial review 👇
I got the chance to test this flight controller pre-release and so far, it has been great. There have been a couple small changes since I flew it but I expect the performance to be just as good here. The new gyro flew great and the VTX was performing consistently and outputting right at 25mw for racing (edit: this is no longer the case with the final version). Adding a receiver to this flight controller results in one of the lightest flight controllers that's ever been released. If the VTX manages to hold up on the finished units as well as it did on mine, I think this flight controller will end up being very popular.

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.
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.
