Оценка эффективности 110х моторов
Overall efficiency and flight time of tiny whoop quad-copters is discussed. Measurements and calculations are performed to get estimation of the motor and propeller efficiencies
Examples of back-of-the-envelope calculations for heli, quadcopters, hoverbikes: electric, gasoline and man-powered
Math shows that maximal hovering time can be easily estimated regardless of type of the copter, battery or fuel.
