Flying squirrel glide ratio is about 1.8-2.0 to 1. (26.8°)

As an aside, Archaeopteryx glide ratio is roughly about 4:1, and a pigeon'sis about 6:1.

Glide angles ranged from 3Â°
to 21Â° with a mean estimated
equilibrium angle of 13.7Â°,
giving a lift to drag ratio
of 4.1:1 and a lift coefficient
of 0.64.

Do they mention how it compares to flying squirrels?
