To calculate expected flight time, use this general formula:
Flight Time = (Battery Capacity in mAh × Battery Voltage) ÷ (Average Current Draw × 1000)
However, real-world flight times are typically 20-30% less than calculated due to factors like:
- Wind conditions and flying style
- Payload weight
- Temperature conditions
- Battery age and health
For example, a 4000mAh 11.1V battery with an average current draw of 20A would theoretically provide about 11 minutes of flight time, but expect 7-9 minutes in real conditions.
