Examining the effect of spring resistance on a radio controlled carís speed
The experimental data and analyzed results support the hypothesis that the spring with a larger resistance will increase the speed of the radio controlled car. However, this is only true to a certain extent, as the effect was only observed for the straight line course. For the course that consisted of corners and turns, an increase in the speed of the RC car was only observed when the car was fixed with springs that had the lowest resistance.
Due to the increase in popularity of the hobby, there is growing demand for remote controlled cars and their accessories. The RC cars meant for hobbyist are usually sold as unassembled kits, as assembling the cars on its own enables hobbyists to learn engineering and operational fundamentals of the RC car. This also helps them to learn how to perform maintenance and upgrading work on their cars.
Try to repeat this science fair project by using a different model of RC car such as the Kyosho brand cars.
The experiment can also be repeated by changing other accessories in the car such as the type of tires used.

Safety concerns:Observe proper road safety - never play on an actual road. Find a safe, secluded place (eg. basketball court) to perform your experiment
