I just finished building a 1/72 HH-60H Rescuehawk using some resin accessories from the Fireball Models set. I used the Italeri kit and it came out looking pretty darn good if I do say so myself.
I will use the Italeri kit again when I build my 1/72 HH-60H Jayhawk (using the Fireball conversion set).
With a little attention to detail, I think it can be built into a very convincing model.
Good Luck,
Pete Brown
