I have the feeling I’ve asked this before, but…
Looks like a Sonex, but not sure, I know that have one version that is a V-tail.
That would have been my guess, if I could have remembered the name. But the tails look like they’re swept differently, and there are longitudinal ‘ribs’ on it that I don’t see on a Sonex Waiex.
Maybe a Davis DA-2?
It’s smaller than the DA-2. Maybe a pure homebuilt designed and constructed by some dude in his back yard?
