Recently KiwiMill shipped out 5 display models for our client, Anaren, representing the circuit boards they make for radars. These will be trade show displays and include a plane, ship, 2 trucks and a satellite that house radars within them. More photos at http://www.flickr.com/photos/ammodelmakers/sets/72157626468589207/.
Our model makers built a Tactical Airport Surveillance Radar model series for ITT. This particular design is called the TASR-2020. Using photo-like images for reference, the majority of the pieces were made out of brass for strength, beauty and longevity. The CNC mill was used to cut the brass parts which were then soddered together. The fixed location unit was built mostly of styrene, which is a more flexible, durable material than plexiglass. The radar dishes were motorized to attract attention at trade shows.
