The Quest for Speed: How Fast Can LEGO Cars Go?

🚗LEGO cars can achieve impressive speeds using various types of motors and propulsion mechanisms.

⏱️I measured the speed of the LEGO cars using a GPS device and a time-trial setup.

🔥Rocket motors provide the highest speed, but they require careful handling and stability considerations.

🔄Gear ratios can affect the speed and torque of LEGO cars, allowing for optimization and experimentation.

🧱The limitations of LEGO bricks and their ability to withstand high speeds and forces became apparent during the testing process.

What was the fastest LEGO car you built?

—The fastest LEGO car I built achieved a top speed of 42 kilometers per hour.

What propulsion methods did you use?

—I used LEGO motors, rocket motors, and powerful RC car motors to propel the LEGO cars.

Did the LEGO cars survive at high speeds?

—Unfortunately, the durability of LEGO parts became a challenge at high speeds, and the cars often experienced structural failures.

What role did gear ratios play in the speed of the cars?

—Gear ratios affected the speed and torque of the LEGO cars. By experimenting with different gear ratios, I could optimize the performance.

Can LEGO cars be faster than regular RC cars?

—In theory, LEGO cars can achieve similar speeds to regular RC cars if equipped with powerful enough motors. However, LEGO parts may not provide the same level of durability and performance as dedicated RC car components.
