Just out of curiosity... with all the fanfare of the X2 breaking the Heli speed record, how does anyone figure the X2, a compound helicopter, can be compared to the current (or previous) record holding Lynx, which achieved the speed record without any thrusting appendages?
And if it did indeed steal the record and non rotor system thrust is allowed, would it not still be trying to catch up the Bell 533, which hit almost 275 knots back in 1969?
