Wow those are awesome! Huey and Hindu look great together. Ive tried several times to build the two but end up throwing them aside. I guess I will have to stick to full size guns. You should take a look at my Mg-42 v2. Awesome replicas!
I got a better suggestion for your windows. Try looking at a LEGO Star Wars creation, such as a Republic Attack Gunship (Set# 7676) or a Republic Gunship (Set# 7163). Those would be far better windows for your Mi-25 Hind cockpit. Try it and see, okay? Also, the Mi-25 Hind is erroneously named as the Mil Mi-24 Hind. Finally, there is a special kind of attachment in LEGO form (I think) that allows for a sort of star-like attachment to your craft. The reason for this is simple. The real Hinds have five blades as opposed to six blades.
