A typical medivac helicopter flies about 160 knots.
A fast aeroplane will be faster than any helicopter, but a fast helicopter can be faster than a slow aeroplane.
Depends on the purpose and make of the helicopter.
249 mph
It can fly at 224 kmh - approximately 130 mph.
The Chinook can fly at about 195 mph.
The typical CRUISE speed of the formentioned two seat trainer style is about 90-105Mph. and the five seat turbine is about 130-145Mph. (as far as MAX speed, I have been to about 155Mph in a Bell 206).
quite fast, there is more drag from the fuselage going side ways and it would be less stable
Sadly Not, it's physically impossible.
The fastest are attack helicopters like Apache, they mostly fly about 230 -250 mph.
How far can helicopter fly on a one tank of gas
It depends on which Apache version: AH-64A=265 mph;AH-64D=295 mph
