Almost all Quadcopters have a short flight time. According to DroneLifeStyle.com, it’s usually between 10-20 minutes. It is advised to carry an extra battery, or even several. Unfortunately, the recharging times range from 45-90 minutes. Looks like doing tricks and flips or changing altitude drains the battery because of the increase in power used on the motors.
