hello! I am an engineering student and am participating in a RC Car raacing comp in my college. The comp requires us to contsruct a RC car using either DC motors or miniature IC engines (4cc-6cc). The track will have many obstacles like sand pits, oil spills etc. The objective is to complete the track in the shortst possible time. I want to know what kind of a frame/chassis should I opt for while building the car. I am not really sure of the importance of the frame in such a small car...will just a simple ladder frame suffice? Also, given the nature of the track, I am thinking of going for indpnt suspensons for each of the wheels. Is it possible to do it?
