gsnow,
I'm pretty new to the forums, but I saw this thread you started...the sites HeavyArty posted were *awesome* for sure!
Here's one other resource you might want to consider:
Verlinden's Lock On #16 publication number 733...has the entire Hind including full engine detail, APU shots, landing gear...the whole bit. Although it's based on a Polish rotor, it's got a great deal of close up shots to keep you busy.
I built R/M's '48 kit before the Cobra set was available, and now I need to get the kit again just to outdo what I had to scratchbuild previously!
