Chnick Felton was the master for CL cardboard 'scale' models. Published perhaps a dozen, possibly more, many in Flying Models, at least some in Model Aviation?
They were not, flat, single thickness wings. Most had the upper surface, only, curved to form a flat bottom airfoil.
Good info on how to crease the bottom of the upper skin to shape, use ribs to form and stengthen it. Fuselages and tails were also of corrrugated cardboard, edged with balsa. Engine and bellcrank mounts were braced and supported with balsa, ply and hardwood as appropriate. Info on finishing exteror, etc.
Most were fairly large, and quite heavy - he used enough power to fly well for scale, i.e., no sharp maneuvering, or inside AND outside figures, etc.
There were similarly constructed RC designs at the time, some with a limited ability for outside 'g'.
Not my favorite way for models to look, but much of the structural materials were certainly of reasonable price!
