A Hellcat?! Besides fitting into the general definition of being a unibody, what exactly do you think a Hellcat chassis and an A-body chassis have in common?
I mean, seriously. Do you actually think that's a legitimate comparison? Because from a technical standpoint you might as well be comparing a Cessna 172 to an F-35. Yeah they're both airplanes, but I wouldn't say the Cessna doesn't need a propeller just because the F-35 doesn't need one. Good grief man.
