Hi Kellyshero,
Like Demon69 mentioned: Fujimi makes one, but also Heller had a 1:50 (darn those Heller Scales) which is better than the Fujimi; the landing gear on the Heller is not as oversized as on the Fujimi, which makes the Heller look a lot better.
I also built the Airfix Gazelle, but I'm affraid 1:72 is actually too small for this helicopter: the rotorhead looks way too massive on the Airfix. If I remember correctly, fit wasn't too good either on the Airfix: I had to cut a major portion of the interior away to make the fuselagehalves fit. Must admit though: overall looks of the fuselage are ok, and can you complain considering the low price of the kit...
Hope this information is of any help, good luck!
