Here's our Kong kit.  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 makes a splendid display piece on its own.
