I didn't have a transparent UH-1, but the one I did their regular UH-1 model
(at least I think it was a Monogram). I modified so that it would spin the
top rotor via an electric motor and a couple of LEGO gears. Luckily on this
model the fuselage cover easily slid on and off, so everything was hidden.
Boy that thing would spin that main rotor *fast*. ;-)

Yes, they also did a non-transparent version, minus some of the inner
framework parts.
Unfortunately, my painting skills weren't that great at the time, so the
overall appearance was rather shabby and like almost all of my (poorly
built) models from that era, it was likely destroyed by fire crackers.

I've seen some pretty shabby looking real ones over the years.
Monogram also did a 1/48 scale Huey and Huey Cobra.
Revell did a 1/32 scale Huey ( in fact they did at least two versions of
it) in 1/32 scale, and also did a 1/32 scale Cobra.
These all were around at the time of the Vietnam War, so Hueys were well
known.
Want to see my favorite Vietnam-era weapon?
The farm tractor company, Allis-Chalmers, goes to war in a big way in a
tiny tank:
