There are several types of Hueys and to the regular person, they all look the same.
The Big difference is the Rotorhead and length of the fuselage and tail boom
D and H models were longer, for troops and cargo.
It had two windows in the sliding door and an oil-filled, tension-strapped rotor head.
The C model was the official gunship. It was a little shorter and had a 540 rotor head (door hinge design ) same as the Cobra.
No oil crap.
The blades are shorter and wider
There was no extra room beside the transmission, but a straight bulkhead across
