What is it they're not used much these days outside of historic craft, but inline piston engines are?
Is it that the radials now fall into a place where they make more power than inline piston engines, but with so much weight it's more efficient to use turbines for the same applications now? Or do they produce about the same amount of power at about the same amount of weight as the inline engines, but with more complexity and timing issues?
Or something else?
