The Sikorsky final flight was on Thurday at the companys test site in West palm Beach, Fla. Â None of the flights taken by Sikorsky were viewed by anyone buyt the company itsself. On their final flight they showed potential customes what the helicopter could do. Â The helicopter itself had a top speed of 290 mph and the potential of the X2 to go even faster @yungjpohnnybravo @TatWZA
