...."Meanwhile, workers are making adjustments to the original Scorpion design. Textron AirLand rushed the Scorpion from design concept to first flight in less than 20 months. The production version allows them to refine the design of certain components. The main landing gear, for example, of the Scorpion demonstrator is an elaborate oleo strut design. It is being replaced with a simplified trailing link gear, removing 90kg (200lb) in the process, Tutt says.
Another change adds 4˚ of sweep to the outboard span of the wing leading-edge. The demonstrator revealed a centre of gravity slightly aft of the design intent, Tutt says. Increasing the sweep angle should correct the centre of gravity position while not affecting speed or manoeuvrability performance, he adds.
Other changes from the demonstrator design include the speed brake, which was bolted on to the top of the aft fuselage as an afterthought. The speed brake on the production version is designed to be flush with the fuselage skin, Tutt says.
More tweaks are being made beneath the skin. Cessna designed the Scorpion with a unique twin-keel hull, allowing the fuselage to accommodate a centerline payload bay. The original design allowed the Scorpion to fully retract a 15in-wide sensor turret assembly. Cessna changed the production design to store a 25in-wide sensor, such as the Sierra Nevada Gorgon Stare wide area surveillance system.
In the nose Textron AirLand is expanding optional payloads beyond the standard weather radar. The production Scorpion will have space reserved to instead house a multimode fighter radar, such as Northrop Grumman’s APG-68 fire control and synthetic aperture system."....

Increased wingsweep isn't really noticeable. That flat belly between the keels for the payload bay is though.
