This isn't supposed to resemble any current helicopter, nor is the name but it does look cool.
About this creation
the Snowfox is a lightweight military helicopter(not a real one). It is supplied with 4 homing missiles(tucked under the wing close to the body of the helicopter) and 2 large short-range rockets at the end of the wings.
From this view you can see the rockets more clearly and the shape of the tail. If you notice the sand colored brick slightly behind the cockpit, a minifigure can hold onto it and be transported when the door is in down position(shown in the second-to-last picture).
If you look at the underside you will notice that the floor will open revealing the landing gear and a chain(thats use will be shown in the last picture).
Here's the back of the Snowfox, you can see the landing gear through the back.
This is the Snowfox in landing position, the walls on either side of the body come down for landing pads and the floor near the back opens for a robotic "foot" to be stood on. Also, the walls beside the cockpit will lower to become a staircase for the pilot to climb down.
The bottom doesn't only store landing gear, there is also a chain in there that can be used in rescue missions(as seen above).
Anything that is unrealistic is meant to be so, don't tell me that it won't be able to fly in real life. This is Lego.
