The Bell X-5 was the first aircraft capable of changing the sweep of its wings in flight. It was inspired by the untested wartime P.1101 design of the German Messerschmitt company. In contrast with the German design which could only have its wing sweepback angle adjusted on the ground, the Bell engineers devised a system of electric motors to adjust the sweep in flight.
PERSONAL NOTE: the plane does not have 4 intakes, but i put 4 of them on this plane to hide the ugliness of the rotators. this does not turn very fast unfortunetly but it has a sweepable wing design to help move COL forward and increase turn speed. althought turning the wing doesnt help alot, but in the long run it there definetly is a difference. -BlueWhiskyYT
