This may be where the tail comes in: to provide stability while the forelimbs
are used for other things. Also, a skydiver equipped with parachute and
harness easily weighs 200+ lbs (even without a tail) and falls like a rock;
the aerodynamics of a small, feathered lightweight falling/gliding creature
may differ.
