It originated from the earlier Klein Motor Sport magazine. History Publishing house H.Bechhold Verlagsbuchhandlung took over the unprofitable title Klein Motor Sport in 1927. In order to revitalize the magazine, the publisher assigned the young progressive engineer and critical automotive journalist Josef Ganz as editor in chief. He started as from the first issue of January 1928. Josef Ganz used Motor Kritik as a platform to criticize heavy, unsafe and old fashioned cars and promote innovative design. The magazine quickly gained in reputation and influence and, in January 1929, was renamed into the more appropriate title Motor Kritik. With the ardent conviction of a missionary , so post war Volkswagen director Heinrich Nordhoff would later say, Josef Ganz in Motor Kritik attacked the old and well established auto companies with biting irony. ref A Revelation of a Secret Love , LIFE International , page 73, October 24, 1960. ref These companies fought against Motor Kritik with law suits, slander campaigns and an advertising boycott. However, every new attempt for destruction only increased the publicity for the magazine and Josef Ganz firmly established himself as the leading independent automotive innovator in Germany. As a Jew , however, Josef Ganz was forced to resign as editor in chief by the Gestapo in 1933. His position was taken over by his colleague Georg Ising , who remained editor in chief throughout the Second World War until the termination of the magazine in 1945.

A friction motor is a simple mechanism to propel toy cars , trucks, some trains, action figures, and similar toys. The motor consists of a large flywheel which is connected to the drive wheels of the toy via a very low gear ratio . The flywheel s axis is perpendicular to the direction in which the toy faces and moves. When the toy is pushed forward the drive wheels engage the flywheel. The flywheel stores the kinetic energy of the initial acceleration and propel the toy toy after it is released. ref http www.patentstorm.us patents 5360367 description.html Flywheel Motor Patent ref These toys were especially popular in the 1960s to 1980s. Some used a zip cord which would directly accelerate the flywheel when pulled from the body of the vehicle. ref http www.upei.ca physics p261 projects flywheel2 Whatis.html What is a Flywheel anyway? ref See also Pullback motor References reflist Category Toy cars and trucks Category Mechanical toys ... more details
