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.They may ask for proof that you have the right to print it, in which case you can refer them to this sentence in the PDF file: You are hereby granted permission to print a single copy of the PDF version of this document for personal use. This brief tutorial assumes that you have a model that you are intending to power with an electric motor (or more than one), whether that be a designed-for-electric model, or a conversion of a glow model.
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...These five steps are described in more detail below.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.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.
How to Register Registering the CD Version Registering the Evaluation Version If You Can't Print the Registration Form If You Don't Want to Register If You Lose Your Registration Using Moto Calc on More than One Computer Moto Calc is a program for predicting the performance of an electric model aircraft power system, based on the characteristics of the motor, battery, gearbox, propeller or ducted fan, and speed control.
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.
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.
