By the use of a 3.5cc two stroke nitro-methane powered I.C. engine, the Redliner transmits power to all four wheels by means of a two speed, automatic gearbox. Controlled through a wireless remote using 27Mhz radio frequency, the Redliner is easily usable within a range of 150 meters. 1. Introduction The described remote controlled car is designed in Solid Works 2008. Supported on an aluminum base-plate 3mm thick chassis, the Redliner is provided with individual suspensions and drive shafts. By the use of servo-motors, the motion of the steering mechanism, braking and propulsion system can be controlled accurately. The braking system includes a common disc mounted on the gearbox output shaft provided with mechanical liners to introduce friction. Differentials provided between the left and right wheels of the front and rear assembly allows the vehicle to grab traction even over loose soil. The 85mm broad tyres with a profile of 15mm and a diameter of 80mm improve stability and transfer the required motion of the gearbox output shaft to the ground. Each wheel, provided with individual suspension systems, including lower and upper wishbones forming a parallelogram being pushed and controlled by the use of two spring assisted shock- absorbers, assist the stability and provide hassle-free control for the driver. The vehicle is controlled using a RF 27 MHz remote controller. 2. Block Diagram The Redliner consists of two main types of components. 1. Structural 2.
