About this Plan

TW-69. Radio control pylon racer model. Wingspan 1200 mm.

Quote (google-translated from the German): "It's no longer a secret: RC pylon races have become established with us. The fact that there are still clubs that are not quite comfortable with the relatively high speeds and individual model pilots for whom the racing models don't look 'beautiful enough' cannot hide this. The pylon races, on the other hand, which took place in this country last year, have all proved to be extraordinarily sporty and appealing to the public, so that in the course of the coming season the remaining reservations will certainly be removed.

As is well known, RC pylon races have been flown in the USA for many years, and the existing extremely rigid rules are a good 20 years old. So it's no wonder that this rigidity has largely inhibited the further development of the models as well as the technical implementation. This alone is the reason for a certain monotony of the 'classic' American pylon models.

For us in Fürstenfeldbruck, holding competitions according to American rules (special model aircraft, corresponding flying terrain, large number of assistants) seemed unattractive and hardly promising. At the previous events, a new RC flying was introduced with simpler rules, which firstly requires sporting performance from the active model pilot and secondly can be followed and observed very closely by the spectators.

After we made the experience that the size of a flight model or the strength of its engines has no decisive influence on the achievable performance, the flight behavior of the model and the flying skills of the pilot are much more decisive, taking into account the severity of the mission, risk of collision, intermediate landings, etc, the following basic rules are applied:

1. medium-sized model aircraft
2. appropriate engine power (5-8 ccm)
3. simple construction
4. good take-off and landing characteristics.

Based on the sizes of our currently most common receiving systems, steering machines, servos, etc, the smallest possible dimensions were determined without excluding good accessibility and maintenance options..."
