Human Ornithopter Problem?

It's a problem that is not so easily analyzed, I think. There are
teams working on real ornithopters now, as well as experts in various
form of "flying suits" used by skydivers. Some of the researchers in
those fields use computational tools, which should be easily tweaked
for 1/6 G to see what happens. Those guys could design a bird suit
that would actually work, even if it means that the wings are actually
attached to the hips or upper thighs, with the arms simply forming the
frontmost edge.
