Flight Duration
18.8 mins

Calculation Methodology

Usable Energy (Wh) = (Battery mAh / 1000) * Voltage * 0.80. Hover Power Draw (Watts) = AUW Weight kg * 150 W/kg. Flight Time (Minutes) = (Usable Energy Wh / Hover Power) * 60.

Important Legal & Educational Disclaimer

Always observe the 80% discharge rule for LiPo battery longevity to avoid in-flight voltage sag and crashes.
