rectangular strip with the surface OF

This cOnical surface Ia the secret Of the
automatic stability Lieut.. Dunno de-
clared The effect In that the aeroplAns
simply balances itself in tho air and
maintains a constant speed az = constant
angle. There IL no necessity 70 balance
the machine either sideways or forward:
il neither pitches nor rolls.
There are two wing haps. one at the

and held them in a fixed position. The
biplane then described very slowly part
