R/C pylon racing became feasible in the 1960s, when the R/C equipment was
improved and finally lead to systems with simultaneous proportional
transmission. The first contests were organized in the USA in the early 1960s.
In the beginning, a distance of 1/10 mile between two pylons was used, which had
to be circled 5 times, resulting in 1 mile flown. Because only one pilot flew
against the clock, it was not comparable to the modern pylon racing atmosphere,
where, at the same time, 3 or 4 pilots compete against each other. During these
days, people like Jerry Nelson, Hal deBolt, and Howard Bonner contributed much
to the development of R/C pylon racing.
The first pylon racing event in Germany took place in 1969, initiated by the
well known Manfred Pick, who is still in the business today. Together with his
team mate Lothar Steinbiß, he was found in the top ranks of most major European
events throughout several decades - and even today, he is very successful in the
circus.
The following graph shows the development of typical times of the European
(in fact mainly German) top pilots versus time.
History of time per lap of European top aces (selected from contest
results).
It should be noted, that some of the variations are due to changes in the FAI
or the national contest rules, but in general, the improvements are the results
of model and engine optimizations. During the first half of the 1980s the
aerodynamics of models and propellers has been examined carefully, which led to
new airfoils and model geometries. During the 1990s the manufacturing quality of
the models was greatly improved through the use of CNC machined moulds and there
seems to be still some movement in the engine area. In 1996 the 70 second
barrier has been broken regularly. The standards have been set quite high
already, which is indicated by the smaller advances during the last years.
Today, times in the order of 60 to 65 seconds are flown by the top pilots.
Most of the information given in the next sections are based on work, that
was carried out in the early 1980s by members of the Akamodell
Stuttgart, Germany. That is why some of the engine and model data are a bit
outdated, but the principles shown are still applicable.
