Very nice! It appears that they are symmetrical airfoil which would explain the pitch stability without any reflex or washout in the wing. It looks like the small size and low aspect ratio gives them a pretty good ability to use weight shift for roll control. Also good for mellow stall characteristics.

LTAHG
Lighter-than-air hang glider called by other names. (Explore: airships, balloons, Zeppelins, dirigibles, blimps, .. "Hang Stat" (F. Colver) )
============================================
_______________________________
1910
inflated LTA aircraft with pilot hung beneath inflated "wing". Gliding occurred at times during descents; the airfoil here was of very low L/D. Buoyancy was the main aim of these kinds of inflated LTA hang glider balloons; they did not call these devicea hang gliders, but rather perhaps "airship."

The series of triangle control frames allowed the pilot to shift his weight or mass along the series; angle of attack would change with the position of the pilot.
Lincoln Beachey is seen flying an airship; the number "2" can be seen on the rudder.
