Looks like a kit plane like John Denver’s.
Not a kit plane.
Denver was killed in a Long EZ, a Burt Rutan design, trying to change fuel tanks with a pair of pliers while on final.
The Long EZ is a canard aircraft - little wing up front (the canard), winglets, two-place tandem.
As for being stallproof, a canard is the only really stallproof aircraft type out there, short of some sort of automatic intervention when the AOA starts to get to the red zone.
