The Aero Club of America exhibited a 50 horse-power Gnome Nieuport aeroplane.
Queen
The Queen Aeroplane Company exhibited two machines, one an aero-boat designed by Grover C. Loening, and the other a Bleriot-type monoplane equipped with a 30 horse-power Anzani motor.
The aero-boat consisted of an aluminum-covered boat, to which were attached in front on an upright structure the main wings, with the motor and propeller just behind them. The power-plant consisted of a 50 horse-power Gnome, which was placed in the boat proper, and drove through a chain the propeller, which was just behind and a little above the main planes. The controlling arrangement was quite novel, and consisted of two horizontal levers resembling the tillers of a boat, which the operator grasped one in each hand.
National
The National Aero Company exhibited a Bleriot-type monoplane which was equipped with a 4-cylinder 40 horse-power Rubel “Gray Eagle” motor and Rubel propeller. The motor was fitted with an acetylene self-starter, which was controlled from the seat.
American
The American Aeroplane Company exhibited a large monoplane with a very low centre of gravity. It was fitted with two 50 horse-power 2-cycle air-cooled revolving motors and self-starters, and was designed to fly with either motor, and to carry six to ten persons.
The First Pan-American Aero Show
It is notable that no engine exhibited at this exposition had more than 80 horse-power, whereas the Liberty motor of 1917 developed 450 horse-power and the Fiat 700 horse-power.
