Why did planes use radial engines? Radial engines have several advantages for airplanes: Radial engines have a relatively low maximum rpm (rotations per minute) rate, so they can often drive propellers without any sort of reduction gearing. Because all of the pistons are in the same plane, they all get even cooling and normally can be air-cooled. Why are radial engines not used anymore? The main reason for this is cost. Radial engines cost more to...
