I don't buy it.
The Supercub is very lightly built and a crash which a balsa trainer has no problem surviving will rip the Supercub to shreds.
Not necessarily.
Light weight also means less momentum. And less momentum means the forces on the plane are lower on impact.
I did my GWS E-Starter very light and it survived a few arrivals that made me expect a pile of pop corn. Damage? Broken props, one bent GWS prop shaft, dented cowl, some scuffed foam. My flying was initially over very long grass, and without landing gear, which may have helped.
