FG-1D Corsair (Goodyear made version of the F4 Corsair) WWII fighter starting & extending the wings

I took this video at the Hanger at 743 in Latham, NY when during their Wheels & Wings show they fired up the FG-1D Corsair named Ruthless II (the Goodyear version of the Vought F4 Corsair). They started it, and then extended the wings. Turn up the speakers, because it's loud!
