Model making technique and history
The building of model aircraft as a hobby it became popular at the beginning of the 20th century. As early as 1913 Biegenwald's book "Flugmodellbau" was published. The rubber motor was recommended as the drive and the possible use of compressed air, CO2 and V combustion engines rudimentarily called. Alphonse Pénaud (1850-1880) was a French air technician. Through his work he gained extensive knowledge of flight technology. He invented which are still used today in model sports rubber motor . The real beginning of free flight was in 1871, when he flew by one Rubber motor with 5g powered flight model "Planophore" in about 13 seconds a distance of 60 m 480 mm, wing depth 110 mm, length 500 mm, total weight 16 g. The propeller had a speed of 250 rpm. His model, with aerodynamic features, had a stabilizing fin in addition to the wing, at the time " Called the Penaud Tax ". It corresponds to the current one tailplane . Today we would refer to this model as a hall flight model.
Building materials were first and foremost everyone types of wood
. Plywood, thin pine strips and paper to cover the wings. later the light and easily machinable but nonetheless tough spread balsa wood
. Today, plastics like GRP fiber composite
- and Foam molded parts and plastic films are used to create the surface and the finish.
Already in the 1930s internal combustion engines
introduced for model aircraft. B. the Kratmo engine. The first successful radio-controlled experiments were carried out in the second half of the 1930s. away 1950 were remote controls
first as bulky, bulky and heavy tube devices, which required large and unwieldy batteries, later with me Transistors widespread through industrial manufacturing. But only from the mid-1960s Proportional systems introduced years ago, in which each rudder corresponds exactly to the deflection of the stick movement Sender follows, with which especially model aircraft can be controlled precisely and safely, really made model flying popular and widespread in society.
