Vought F4 Corsair

Possibly a stupid question but here goes,  Is the AU-7 and the F4-7 the same aircraft?

 

Thank You

Thank You

Your nomenclature is puzzling. The USMC attack version of the Corsair was the AU-1. All the rest of the family that I'm aware of were F4U-X where X was anything from 1 to 7. The F4U-7 and the AU-1 were similar. Here's a quote from a Britmodeller thread that explains the difference between AU-1 and F4U-7:

 

The AU-1 is based on the F4U-5 airframe, with a single-stage supercharged R-2800. The F4U-7 was based on the AU-1, but with (literally) the engine from an F4U-4, which required adding the chin scoop. 
Short history lesson: 
The -5 extended the forward fuselage by a foot, and had a "pear-shaped" cross-section to accommodate the air inlet ducting of the twin-spool supercharger. Even though the AU-1 didn't have a second-stage supercharger, the "pear-shape" remained, with the cheek inlets removed/faired over. Without the need for intercoolers, the wing-root mounted oil coolers migrated into the fuselage and the vane arrangement in the wing root intakes was simplified. 
Then along come the French with an order for 100 examples of a more powerful/higher altitude version of the AU-1. Vought's minimal tooling solution for this low-volume custom order was to install engines (quite literally) stripped from surplus F4U-4s into the AU-1 airframe. The main visual difference was the installation of the chin scoop. There are other minor differences, but removing the chin scoop from a -7 will certainly result in a satisfying AU-1.

seawinder, thank you! It's useful for me too.
