YouTuber builds drone that flies long using only solar power

YouTuber Luke Maximo Bell has developed a solar-powered drone capable of potentially flying indefinitely by harnessing energy from the sun. Bell optimized the drone for maximum efficiency, using lightweight, high-performance components such as the T-Motor Antigravity MN4004 300kv brushless motor, which features an ultra-thin design, reduced weight, minimal energy dissipation, and an advanced cooling system for stability. The drone frame was fully assembled with careful wiring of motors directly to the electronic speed controller (ESC) and flight controller, enabling a streamlined, efficient power system. The drone also incorporates T-Motor NS 18×6 carbon fiber propellers that provide high thrust, efficiency, and durability, contributing to long, stable flight times and improved maneuverability. Bell’s design achieves a remarkable efficiency of 17 grams of lift per watt at takeoff, which is 24 times more efficient than his previous record of 0.7 grams per watt. The drone uses a T-Motor F
