Motors for flying machines must be light in weight,
of great strength, productive of extreme speed, and
positively dependable in action. It matters little
as to the particular form, or whether air or
water cooled, so long as the four features named are
secured. There are at least a dozen such motors or
engines now in use. All are of the gasolene type, and
all possess in greater or lesser degree the desired qualities.
Some of these motors are:
Renault—8-cylinder, air-cooled; 50 horse power;
weight 374 pounds.
Fiat—8-cylinder, air-cooled; 50 horse power; weight
150 pounds.
Farcot—8-cylinder, air-cooled; from 30 to 100 horse
