Scale model tug boats are often built to include scale drive systems. They use standard propellers and rudder(s), Becker rudders, Kort nozzles, steerable kort nozzles, Z-drives or Voith-Schneider cycloidial drives. Clubs will often host maneuvering competitions where participants are tasked to run their boats in the most realistic manner possible.
Currently the majority of model ships owned by Task Force 72 members are military vessels however this is slowly changing as more non-warships are completed. In fact the joint winners of the Wentworth Shield for best model at the 2007 Annual Regatta were two non-warships, the lighthouse and navigation aids tender Cape Don and the USS Charles Robinson, a Liberty Ship.
HowStuffWorks maintained a large number of podcasts, hosted by its staff writers and editors, but now all former HSW podcasts are owned and operated by iHeartRadio.. Stuff You Should Know: an audio podcast and video series on various topics from all fields of interest
1:10 scale radio-controlled car (Saab Sonett II)A radio-controlled model (or RC model) is a model that is steerable with the use of radio control (RC). All types of model vehicles have had RC systems installed in them, including ground vehicles, boats, planes, helicopters and even submarines and scale railway locomotives.
The Water Line Series was created by the Shizuoka Plastic Model Manufacturers Association in May 1971. It is a collaborative effort by three manufacturers to produce constant scale models of most of the ships of the Imperial Japanese Navy during World War II, [5] in their first series, and then an ongoing collection of 1/700-scale kits of warships of the world.

A scale model of the Tower of London. This model can be found inside the tower. A scale model of a hydropower turbine. A scale model is a physical model that is geometrically similar to an object (known as the prototype). Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than ...
Egyptian ship and boat models are perhaps some of the most well-preserved types of ship models available to archaeologists. Ancient Egyptian ship and boat models were most frequently placed in tombs of prominent people as "magical substitutes for the actual objects which the deceased has used in life and which he expected to use again in the ...
Consequently, the scale factor for the mass (M) and displacement is the same as that for the volumes, i.e.: S (M) = S 3 (L) = 25 3 = 15 625 Similitude of forces (F): If the external forces on the model are in similitude, like the shapes, masses and inertia, the model's movement will be in similitude. It can thus be shown that the forces (F ...
