Looks like a “homebuilt airplane”. Google it or Experimental Aircraft Assn. It does not look like any plans-built homebuilt that has been covered by Air Progress or Sport Aviation over the last 40 years or so. Looks like they were making it up as the went along. Looks like the wing rib was awfully far back for it to balance. Don’t think it would fly very far (maybe over the ditch at the end of the runway).
100% agree. CG is clearly too far aft. You can SEE the obvious piston engine. Looks like a crappy DIY project.
