And if you don't know the aerodynamic characteristics of your plane, Moto Calc's lift and drag coefficient estimator will make short work of determining them.
This will fill in the Moto Calc Workbench window with settings corresponding to the selected suggestion.
At this point, you can modify any of the parameters that you wish.
The pieces of information you need to supply are: If you already have a good idea of the power system components you want to use in your model, you may want to skip using the Moto Wizard and go straight to the Moto Calc Workbench. If you are unhappy with them (for example, suggestions involving a very large number of cells, or only brushless motors when you would prefer brushed), return to the Moto Wizard's option pages and narrow your preferences.
At this point, you can also print the Moto Wizard's suggestions by clicking the Print...
Moto Calc will predict weight, current, voltage at the motor terminals, input power, output power, power loss, motor efficiency, motor RPM, power-loading, electrical efficiency, motor RPM, propeller or fan RPM, static thrust, pitch speed, and run time.
By producing a table of predictions, Moto Calc lets you determine the optimum propeller size and/or gear ratio for your particular application.
The last line of the summary, labeled "Stats", summarizes the predicted performance of the model.
Below this you will see a table of predictions at different airspeeds, estimating things like current consumption, input and output power, and so on.

After a few iterations, you should have narrowed down your choices to a few power systems suitable for your model and your requirements.
