Futuristic prototype helicopter promises to be world's fastest

The Sikorsky X2 isn't even a finished vehicle yet and it's already
broken the rotorcraft speed record of 249 mph set in 1986 — though just
barely. Then again, at 258 mph, the X2 is just getting started.
















The first thing anyone notices about the X2 — Sikorsky, it's worth noting, was founded by rotorcraft pioneer Igor Sikorsky in 1925 — is its double-decker, triple quadruple
blade design. It's also got a six-bladed prop in the back, and it's all
designed to give the craft excellent handling even at high speeds.




The X2 will definitely need that kind of control, as the designers
want it cruising at over 285 mph by the time they're done. That'd be
over 100 mph faster than, say, an Apache attack chopper, which tops out
at around 175 mph.

Looks kinda... "derpy".

As long as it flies quickly, though I'm questioning the appeal of this helicopter when comparing to a proper VTOL aircraft.
