Speed Up Your RC Car!

Speed Up Your RC Car! | Science Fair Projects | STEM Projects
Are you ready to make your RC car go faster? In this project, you will use a remote-controlled car and different springs to find out how the spring resistance affects the car's speed.

Hypothesis

The hypothesis is that a firmer spring will increase the speed of a radio controlled car.

Method & Materials

You will set up two courses, one straight line and one with corners and turns. You will install the RC car with different springs and measure the time taken to complete the 10 meter course.
You will need an RC car, a high resistance spring, a medium resistance spring, a low resistance spring, a spare battery, 80 empty soda cans or bottles, a piece of chalk, a measuring tape, a string (10 meters long), a stop watch, and an unused car park area.

Results

The results showed that the springs with large and medium resistance increased the speed of the RC car for the straight line course. However, for the course with the corners and turns, the speed of the RC car was observed to be the fastest when it was set up with springs that had the lowest resistance.

Why do this project?

This science project is interesting because it shows how changing the spring resistance can affect the speed of a radio controlled car.

Also Consider

Consider repeating this science fair project by using a different model of RC car such as the Kyosho brand cars. You could also repeat the experiment by changing other accessories in the car such as the type of tires used.
