World's Fastest Helicopters
The first time that I ever went flying was in a Bell 47 helicopter at the county fair. The fastest speed that it would go was 91 kts. (169 km/h). Helicopters have developed a lot since then and it got me to wondering what is the speed of the fastest helicopters now?
Here is a list of the ten fastest helicopters in the World as of this year (2017 Listed in order):
