Since 2004 e Calc provides web-based quality services to simulate, calculate, evaluate and design electric brushless motor drives for RC pilots of airplane, multi rotor, UAV, helicopter and EDF jets. e Calc 's motor database is the most comprehensive on the web.

If your Current, el. Power or RPM are over the manufacturers. limits your motor, controller and/or battery may take damage! Verify before flight by measurment!

Feb 9, 2014 · eCalc is a powerful tool to answer questions like "will that motor work" or "what will my flight time be"? You can use it as a "what if tool" to design your multirotor. For example, what if I change the props from 13x4 slow-fly to 14x5.5 E props?

Feb 17, 2014 · ECalc tells you something about the performance for each type of flying. For a given motor and payload combination, eCalc estimates the "flight time," "mixed flight time," and "hover flight time."

May 26, 2014 · Remember, eCalc is just a tool. It's not always going to be super accurate (but often is), but it really helps you understand the relationships between components. Once you get used to it you will value it and gain great insight into how each MR parameter affects the …

Sep 18, 2015 · Drone-Configurator is a alternative to ecalc as it can simulate the drone behavior but it works a different way. Instead of basing our simulation on motor specifications, we choose to use real life benchmarks to be as close as possible to the reality.

eCalc are (software) services for simulation, calculation, design or configuration of electric drives and brushless motors for the model pilot of airplanes, multicopters, helicopters and impeller jets.

Always define the frame size first - then the propulsion with eCalc and use the largest possible propeller diameter. Calculation with available components: Enter the all up weight (incl. Camera), number of rotors and the configuration - read the hints regarding flat vs. coax...

Jul 6, 2022 · The ecalc website is very useful to do estimations for models, however I haven't found how to choose correctly the motor options for generic brushless motors like these In motor choice option ther...
