O Brabham BT52 foi projetado por Gordon Murray para a temporada 1983 da Fórmula 1, pilotado por Nelson Piquet levou o piloto brasileiro ao seu segundo título mundial. O carro parecia uma flecha, para compensar a proibição do "efeito solo" foram retiradas as caixas laterais que antes sugavam o carro contra o solo e agora com o fundo plano acabavam por suspende-lo como uma asa de avião. O monocoque era feito de alumínio e fibra de carbono e o motor BMW 1500cc turbo produzia brutais 1300 hp nas versões de treino e 700 hp para corridas. O kit é um short run produzido por um amigo, escala 1/20 como sempre.
The Brabham BT52 was a Formula 1 car designed for the Brabham team by South African Gordon Murray for the 1983 F1 season. After the ground effect cars were banned at the end of the previous season, the FIA mandated that all F1 cars be designed with flat undersides for safety reasons. The previously crucial sidepods were now generating lift rather than suction and so the BT52 had short, angular sidepods to keep lift at a minimum. The car featured a distinctive dart-shaped profile and oversized rear wing in an effort to claw back as much downforce as possible. The monocoque was built from aluminium and carbon fibre composite to keep weight as low as possible. The car was powered by the massively powerful BMW M12/13 turbocharged engine which produced about 1,300 bhp (970 kW) in qualifying trim, detuned to around 700 bhp (520 kW) for the races proper. The 1983 season saw refuelling stops reintroduced into F1 after successful experiments in 1982. The BT52's fuel system was designed with this in mind, and had a small fuel tank positioned high up behind the driver. The car was easy to drive and Nelson Piquet used it to good effect that season. Fighting with Alain Prost in the Renault and René Arnoux of Ferrari, it seemed he would lose out on the title after a run of mid season bad luck. But after fuel supplier Castrol developed a special batch of fuel and further development to the car was done, he became the first driver to win the world championship with a turbo engine after winning three races and scoring consistently. Brabham finished third in the constructors' championship. Here is the BT52B version, used in the second part of the Championship. Short run home made Brazilian kit, 1/20th scale.
