Disclaimer: The calculated values are only approximate.
The calculations are based on assumptions of Battery, ESC & Prop performances, which may deviate from the real.
The accuracy is usually about ±12%. However, it is strongly recommended to measure the actual max values before flight.
We do our best to provide the highest possible accuracy, but if you spot bugs, significant discrepancies or have suggestions,
