I agree that the auxiliary wings for thrust is less than deal for an ornthopter but that is just what the propeller is except that it rotates rather than oscillates.Probably the most successful ornithotper I've heard of is Adalbert Schmid's, which used fixed wings for lift and a small pair of flapping wings for thrust. That is analogous to using legs to propel a wheeled car like Fred Flintstone It works, but you gain no functional advantage over any other kind of thruster.
This concept of auxiliary flapping wings would be an improvement for most any motorglider. It eliminates the need to stow and unstow the propeller or the need to feather the prop for gliding. Best of all it is ready to immediately add energy with two or three quick flaps and quickly return to the gliding mode.
