G'day i was just wodnerign if anyone could give me there opinions on who makes the best 1:72 hueys suitable for nam, preferably slicks, cheers

I believe the Italeri ones are very good and affordable. At one time they made a plethora of AH-1, OH-6, OH-58 and UH-1 helicopters. Although for some reason they didn't do an AH-1G. A lot of the others out there (Hasegawa) are older kits.

If you are looking for 1/35th scale, then MRC/Academy is your best bet. They make a B/C model that is awsome, along with a great AH-1W. The old Revell 1/32nd scale UH-1H and AH-1G are good kits too, a little long in the tooth, but can be built great with a little TLC. The new Panda Hueys are O.K. They are thick on detail and have some lack of detail, but they do offer a UH-1H Slick in 1/35th scale.

I agree with Sabot, especially if you want 1/72 UH-1B C models. Italeri, Fujimi and Hasegawa all make good UH-D models.
