Rescue Chopper

A miniature rescue chopper is placed on top of the lighthouse as a wind vane.

I stumbled upon several types of choppers while searching for reference images. Every type had its own characteristic outline.

The first one was a Bell UH-1 (used during the Vietnam war), the second one a Sikorsky S-76 or Super Puma, the third one an R22, and the last one a Chinook.
The exact name was not important; the overall shape was.

I chose the first one. The shape was perfect, and this kind of chopper was used for rescue operations as well.

The second one was too big and the third chopper too small/fragile. The last one was also too big - the roof would collapse underneath its weight and/or be blown away as a consequence of its big surface - and it was too army-related.
