The study examined many problems such as efficiency improvement or the safety noise of a windmill for small vertical axis model wind-generated electricity to be called "a Cygnus Mill". The quantity of generation increases as I raise number of revolutions, but there is a threat that I have bad influence such as a fall of the safety or the increase of the noise. Therefore I examined a condition to improve performance and efficiency without raising number of revolutions. I changed a wing-shaped installation angle in one's study in various ways and measured it and tested it. As a result, I added an installation angle and understood that a change had an influence on quantity of generation and efficiency to a minus, (1) As an attack angle rises to a minus, the circumferential speed ratios decrease. (2) As an attack angle rises in a plus, the circumferential speed ratios increase.
