New user here,
Ive always been fascinated with RC helicopters, and helicopters in general.
Ive tried researching on Google, with few answers to my question:
What mass-produced helicopter (minimum 250 made), civilian or military, any country of origin, has the longest range?
And, assuming the helicopter was designed to be outfitted with additional fuel tanks and those tanks were installed and used.
Helicopters that have mid-air refueling capabilities extending the range would count, but assume that mid-air refueling is not done and the longest range is based upon only one initial fully fueled helicopter.
Thanks for any input!
