Yep, Flywilly……..
https://flighthobb.exblog.jp/i0/ as mentioned, currently only available from them in fully built form $$$$ but I see he occasionally does this to get some advance units out there while he's finalizing the instructions and kit layout. I've been told by a local that it's a very good design and is an "honest flyer" which I interpret to mean no bad habits and predictable in all flight aspects........like his other designs.
