I have test flown this AliExpress F4 FC and seems to perform as described. The board came with Ardupilot installed, and from the looks of it is a strip down version of Matek-405-TE firmware. I asked the seller to provide the firmware file so perhaps it can be added in Ardupilot firware library.
It would be good if some developer can create a pull request and add to the Ardupilot list.
Here is the test video:
