I'm not part of that discussion. Note though that we're interested here on Firmware development within the PX4 framework. There are already dozens of great boards and great racing codebases out there.
Our interest is to bring racing to a larger ecosystem and improve the overall outcome by combining forces. A port of the racing Firmware of your choice onto Pixracer is great, but its not going to be any different from existing racing boards.
What we want is a competition of estimator and control algorithms within a consistent ecosystem and codebase (which will make them comparable), not a competition of boards or codebases in a very fragmented fashion (like it is today).
