Recently, a DIY quadcopter powered by the ESP32 microcontroller, with a total cost of around $155, clocked a remarkable top speed of approximately 67 miles per hour (or roughly 107 kilometers per hour) during real-world flight tests. This drone, dubbed "ESP-Blast," was ingeniously designed and constructed by YouTuber and DIY enthusiast Max Imagination. He has shared the entire building process and flight test videos on his channel, proving that even budget-friendly, compact platforms can achieve outstanding performance through meticulous design.
