I want to make FAst toy car of about 10x10x20 any innovative suggestion??? Answered



At some hobby stores you can buy high speed but still small gas or electric engines for rc places. I suggest using one of those.

Still with the fixed line along the floor for guidance - Suggest catapult for acceleration.

How fast is fast - Suggest rocket power on a fixed line

for me fast==around 7 m/sec and without using any combustion or exothermic rxn
