Here's our Kong kit.  This kit builds into a HUGE model. The large size is over 39" (1 meter) high, the giant size an amazing 59" (150 cm). In spite of its size it can be displayed on a fairly small shelf (though to operate a bit more space is needed!)  You can see the details of the model in the photos below.  The airplanes are fixed to long arms which are mounted on a spindle. The kong is connected to a concealed thread inside the model; the thread passes round the airplane spindle and then to a weight which hangs inside the tower. When the weight descends the airplanes spin and Kong climbs the tower.  Kong is articulated; as he climbs his body moves first one way then the other.

The model is very striking, the skyscraper (being so large) makes a splendid display piece on its own. You can order your 'KONG' kit on our shopping cart page, here
