412.7 km/h RC car smashes world speed record thanks to British engineer.

World speed record shattered in radio-controlled car racing

According to ITC.ua — Техно: British engineer Steven Wallis has set a new global benchmark for radio-controlled cars, pushing his vehicle Mach Reaper to an incredible 256.47 mph (412.7 km/h). This achievement capped off an eight-month engineering initiative called Project 250, during which Wallis also hit 250.67 mph (403.4 km/h) at the ROSSA event.

Key technical upgrades behind the record

Several engineering refinements played a critical role in reaching this milestone:

• Wallis swapped heavy cooling radiators for custom-made plates, trimming 600 grams (1.3 pounds) from the car's weight.
• Wheel diameter was reduced from 99 mm (3.9 inches) to 94 mm (3.7 inches).

These modifications allowed the Mach Reaper to hit a record-breaking 256.47 mph (412.75 km/h) at the Yes Mate Speed Event, making it the fastest radio-controlled car ever built.

Wallis had previously designed a car called The Beast, which set a speed record of 234.7 mph (377.7 km/h). Despite having only five weeks to prepare for this new attempt, he and his team managed to surpass his earlier achievements through skill and dedication. He commented:

“The high-speed RC community is incredibly welcoming, and this record belongs to everyone who helped make it happen.”

With this feat, Steven Wallis has not only claimed a new world record but also highlighted what modern engineering can achieve in the world of radio-controlled vehicles, continuing a legacy of innovation and speed in the field.

This record marks a major milestone for RC cars, showcasing how advanced engineering and creative problem-solving can unlock extraordinary performance. Project 250 in particular demonstrates how research and experimentation can raise the bar in this niche. The success is expected to inspire other engineers and enthusiasts to pursue further breakthroughs in radio-controlled car technology.
