It's definitely the FT Spitfire, I finished one a few weeks back although mine is a highly modified version, there is no mistaking the FT designs of the build. And only one way to get a FT build is to watch FT. It would be cool if he speaks up.
Es sieht sehr schoen aus! I've found not everyone that watches FT participates in the forums. I've run into several people at my local spot that watch FT videos and can talk carry on a conversation about FT personalities but will probably never find themselves in the forums. That's cool finding an FT plane "in the wild!"
