You score points for entertainment value as well as speed, so go all out and come up with something completely mad. Bodywork is highly recommended, but not mandatory as long as the car has a strong theme and meets the rules. ==Chassis== ===Wood=== The chassis for CYBR TRK was constructed from wood, mostly decking frame offcuts, utilising recycled hoverboard components wherever pos...")

The operation of the kill switch should be obvious and it must be accessible so it can be used by marshals in an emergency. ===Removable Links=== An appropriately rated battery connector can be fitted with a wire link, which stops current flowing out of the battery when disconnected ===Isolators=== Battery isolator switches for...")
