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.
Using color coding, the table will also indicate the model's predicted stalling speed, optimal flying speed, and hands-off flying speed (these speeds are generally at less than full throttle). button at the bottom of the in-flight analysis to display the Mot Opinion page, which will give you a plane-English description of how your plane will fly, and any potential problems with the selected power system.
Based on the information in the in-flight analysis and Mot Opinion report, you may wish to revise or refine your power system.
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.
If you are a bit more experienced, and know some of the components you want to use to power your model (for example, a particular motor or battery), you can tell the Moto Wizard this and it will try to choose a suitable power system using those components.One way to do this is to return to the Moto Wizard (select Moto Wizard...from the Project menu in the Moto Calc Workbench window) and either select another one of the Moto Wizard's suggestions (step 1), or change some of the options and have the Moto Wizard generate new suggestions.The Moto Calc Workbench Specifying Motor Information Specifying Battery Information Specifying a Drive System Specifying a Speed Control Specifying Airframe Information Specifying Restrictions Options What is a Database Browser?Finding an Item Selecting an Item Finding a Similar Item Deleting an Unwanted Item Printing a Database Table Exporting a Database Table Importing into a Database Table Updating a Database Table Finding the Maximum Efficiency Point of a Motor Gearing and Propping for Maximum Efficiency Gearing for Maximum Thrust Choosing an Alternate Motor Making Use of the Color Coding Frequently Asked Questions Moto Calc is a Simulator All Propellers are not Created Equal Motor Characteristics can Vary Static Thrust can be Misleading Consider the Pitch Speed Catalog Data can be Sloppy All Ducted Fans are not Created Equal Motor Temperature Estimates are Only a Guide Free 30-day Evaluation Why Register?
