Also for the Apache, there are the Hasegawa 1/48th AH-64A and AH-46D Longbow Apache kits, both of which are fantastic kits. Academy and Italeri also have Apache kits in 1/48th scale, but the Hasegawa kits outclasses them all in most respects. They have their fiddly side (what helo doesn't
), but the level of detail and overall finesse make the Hasegawa kits the best of the bunch.
As for the Hind, there is a company called Minihobby (affiliated with Trumpeter in some capacity) who made a Hind E and Hind F. There is some debate as to the origins of these kits as one camp believes they are modified Monogram kits (with recessed panel lines, cripser detail) while others say that these are Minihobby/Trumpeter's own tooling. There is the afore-mentioned Monogram kit and the Revell of Germany reboxing as well.
