Calculate Flight Time of LiPo Battery

Before we can calculate flight time, we need to know the average amperage the quadcopter will draw.  Once we have the average amperage draw we can then calculate flight.

To calculate flight time, take the battery’s capacity in amp hours, then divide that into the average amp draw of the quadcopter and then multiply it by 60.  The total is the flight time in minutes.

For Scout, I chose a 11.1 volt 30C 3000 mAh LiPo battery.  I calculated the average amp draw of Scout to be around 20 amps.  This will give me a flight time of 9 minutes.
