Smallest DIY ESP32 Brushless Rocket Drone A maker recently documented the development of ESP-BLAST, a custom aerodynamic “rocket drone” designed for high-speed flight. Unlike typical quadcopters with exposed frames, this drone uses a streamlined bullet-shaped body to reduce drag while four small 1104 brushless motors drive 2.5-inch propellers. At the center of the system is an ESP32-S3, which acts as the… |
