Hoe gaan dit? Hartlike welkom by SlotForum! Daar is heelwat Suid-Afrikaaners hier!
There is quite a lot of slot racing at all levels in South Africa, especially in the Johannesburg / Pretoria area. In fact, the South African Model Car Association (SAMCA) has been organising national events ever since 1963!
A good starting point would be to visit the Slot Cars South Africa
website, which lists the contact details of some of the clubs. There are quite a few more.
To add to Ken Rs reply, the designation of the cars depends on the era raced, but they are generally known as Sports Prototype cars. The long-tail Porsche 956/962 Le Mans cars (as produced by Slot.it) raced in Group C, as did the short-tail versions in other World Sports Car Championship series races. The short-tail versions also raced as IMSA GTP class cars in other series (mainly in the USA and Japan).
This is my favourite version of the 956:-
Between 1953 and 1961, the world championship was known as the Sports Car World Championship, and the title went to the leading manufacturer. At end of 1961 the FIA introduced the GT (Grand Touring) championship, technically ending the sports car championship, although the organisers of the Targa Florio, Le Mans, Nurburgring and Sebring races offered the Challenge Mondiale de Vitesse for prototype sports cars.
In 1968 the FIA introduced a new World Sports Car Manufacturers Championship for Competition Sports Cars (Group 4) and Prototypes (Group 6). This was still for manufacturers only. A new championship was introduced in 1972, ending the distinction between Group 4 and 6 cars, and was called the World Championship for Makes for Prototype Sports Cars (Group 5) and GT Cars (Group 4).
From 1976, only Group 5 cars were allowed to race, and in 1981 a drivers championship was introduced for the first time. Group C was the Sports Prototype class introduced in 1982 along with Group A and Group B for production cars. The series ran in varying forms from 1982 until 1993, when a change of engine regulations killed it. The championship was renamed again in 1986, becoming the Sports-Prototype World Championship.
