For example, if the Moto Wizard is suggesting a 4:1 gearbox and 12x8 propeller, but you know you can only obtain a 3.7:1 gearbox, change the gear ratio (and perhaps decrease the propeller size slightly).You may also want to specify ranges for some parameters (for example, if the Moto Wizard suggested 14 cells, you might want to try 12 to 16 cells). from the Project menu, type in a name for your project, and click OK. button to generate an in-flight analysis (if you specified any ranges in step 2 above, you will get a static analysis, from which you can pick one result and click the In-flight... A summary of the project (motor, battery, speed control, airframe, etc.) appears at the top of the analysis.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 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.
The Moto Wizard is described in great detail in its own section of this manual, so we won't repeat it all here. The Moto Wizard consists of a number of pages on which you answer some basic questions about your model, it's intended performance, information about where you fly, and any preferences you may have.
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.

You can specify a range for the number of cells, gear ratio, propeller diameter, and propeller pitch, and Moto Calc will produce a table of predictions for each combination.
