Estimates based on manufacturers provided constants using E-Calc. High Quality 700mah used as trial cell in calculations. Actual performance may vary depending on components used, accuracy of data as provided by manufacturer, quality of ESC, weather and many other variables. Note, static thrust numbers are typically higher than calculated with prop sizes 6" and under.
