Brief

The NUS 100% Solar Quadcopter Team demonstrated a battery-free quadcopter in a tutorial/demo format, sustaining 77 minutes of continuous flight on solar power alone. The achievement shows extended endurance possible without onboard energy storage; video footage and technical publications are linked via Aaron Danner's channel and the Danner Group website.

Why it matters

NUS 100% Solar Quadcopter Team achieved 77 minutes of continuous flight on 2026-04-10 using a fully solar-powered quadcopter with no onboard battery.

Key details

The project is documented by Aaron Danner's channel; additional publications and prior drone details are available at http://danner.group and team contact is dewen_97@nus.edu.sg.

Source evidence

Students in the National University of Singapore (NUS) 100% Solar Quadcopter Team achieved 77 minutes of continuous, fully solar-powered flight. This 100% solar drone does not have a battery on board, and thus is able to have a significantly extended flight time.
