    Single vs twin row

    Was there any particular durability difference between the Pratt and Whitney twin wasp 1830 and the wright cyclone 1820. Seems the 1830 would be much more expensive to manufacture considering the same horsepower output?

    Radial vs radial

    Any advantages with the Wright cyclone 1820 over Pratt Whitney 1830? Seems the 1830 would be more complicated and expensive for similar horsepower.
