1:72 Scale  Diecast metal and plastic parts – Hughes OH-6 Cayuse - Low Observation Helicopter - Length: 5" (from tail to tip of rotor at the front)
Rotor span: 4.5”
For this particular model the tail rotor DOES NOT MOVE. Moreover, the model is TAIL HEAVY, so it won't be able to properly rest on its skies. That is why all photos show the model mounted on the display stand. The display stand has the model's info such as country, flag and scale.
Since this model is so small, all the pieces are very small and fragile. Special care is needed when handling. The main rotor's blades are already assembled. There is nothing to assemble.
These helicopter models are really not toys, they are not made to be played with. They will not last long if played with. Moreover, these models are made to look realistic and faithful to the real thing, so little parts like landing gears, skies, weapons, pods and antennas are made from small parts and are very fragile.
The maker of the model, Amercom, really did a good job with the model, the diecast metal construction feels quite heavy. The metal seems too be more rigid and thicker than comparable 1/72 scale models. The panel lines and details are very clear and crisp.What really caught my attention, however, is the way the markings and coloring are done. 
These models come in what could be described as a disposable blister pack
sandwiched between two transparent plastic shells and then glued/attached to a piece of cardboard with the branding info. There is really nothing spectacular about the packaging, but at the end, the packaging is supposed to be disposable and with the sole function protecting the model, which it does very well.
Unlike bigger models, there is nothing to assemble for these models. All weapons and fuel tanks are already attached to the model. One just needs to open the pack and display it (or play with it).
The Hughes OH-6 Cayuse (nicknamed "Loach", after the requirement acronym LOH — Light Observation Helicopter) is a single-engine light helicopter with a four-bladed main rotor used for personnel transport, escort and attack missions, and observation.
