232mph
The fastest are attack helicopters like Apache, they mostly fly about 230 -250 mph.
It depends on which Apache version: AH-64A=265 mph;AH-64D=295 mph
Not enough information has been given to answer the question. How fast is the helicopter going per mile?
292 RPMs, the speed of a propeller is limited by the speed of sound, rotor tip speed can't exceed it. The Apache rotors are 14.63m across. To see other specs. see link below.
A fast aeroplane will be faster than any helicopter, but a fast helicopter can be faster than a slow aeroplane.
The US Marines needed fast, armoured helicopters capable of heavy hitting.
An Apache helicopter, such as the AH-64 Apache, has a maximum speed of approximately 140 to 165 knots, which is about 160 to 190 miles per hour (257 to 306 kilometers per hour). However, its operational speed is typically around 120 knots (about 138 miles per hour or 222 kilometers per hour) for mission effectiveness. The helicopter's speed can vary based on factors like weight, altitude, and environmental conditions.
it depends how fast its going
Depends on the purpose and make of the helicopter.
It might have to do with something not balanced,Check the rudder,the nose,maybe even the throttle could throw the helicopter off.I know for a fact if you travel really high really fast you will wobble.
A typical medivac helicopter flies about 160 knots.
