The Aeromotor 
STANDS THE RACKET

The AEROMOTOR is made of the very lightest and toughest stuff -chrome nickel and vanadium steels, aluminum, manganese bronze, etc., without stint of time or money. And not a pound has been taken off at the expense of strength.

The AEROMOTOR is made by the workmen and designers who built the motor-boat engines that for five years held the Detroit championship against the speediest racers in the United States. 

It's the systematic designing of the parts that makes the AEROMOTOR so remarkably compact. The manifold, for instance, is built into the cylinders, and the mechanical oiler into the crank case.

When you start into the air for that trying first flight you'll have enough to think of without worrying about your engine. If your engine is an AEROMOTOR you won't have to worry. You can be sure the AEROMOTOR will stand by you as it has stood by aviators scattered over 14 states and several foreign countries. "The AEROMOTOR stands the racket," they tell us.
