The engines (also commonly called the “Twin Cyclone”) turned three-bladed Hamilton Standard Hydromatic constant-speed propellers with a diameter of 12 feet, 7 inches (3.835 meters) through a 0.5625:1 gear reduction. The R-2600-23 was 4 feet, 10.32 inches (1.481 meters) long, 4 feet, 7.1 inches (1.400 meters) in diameter, and weighed 2,056 pounds (933 kilograms).
