That model has nothing to do with the Yatsenko brothers
Brett stated that this model was a kit build
With the current BOM you can purchase the wings,flaps,stab elev,fin check cowls,rudder built by other. Construc the fuse install controls,take apart hardware and paint it’s legal

Not the current rule at all. You are allowed to purchase the wing or the tail surfaces or the fuselage. "One Major Component" is the way it's written.
I believe the previous rule required the owner to install the bellcrank and do the covering and finishing. Cheek cowls and come-apart* hardware are not required, of course.

* Here in the NW, we refer to it as "come-apart" hardware, after seeing a variety of failures (by most of the users, usually only once each).
