After a few iterations, you should have narrowed down your choices to a few power systems suitable for your model and your requirements.
Moto Calc's graphing facility can plot any two parameters against any other (for example, lift and drag vs. If you have particular requirements, such as a minimum run time, maximum current, or maximum power loss (which is dissipated as heat), you can use Moto Calc's filter facility to filter out the unacceptable combinations.
To reduce the amount of information you have to deal with, Moto Calc comes with a database of motors, cell types, gearboxes and propellers, speed controls, and filters.
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.
You can then use the rest of Moto Calc to investigate one or more of the suggestions in detail, and then use Moto Calc's Mot Opinion feature to get a plain-English analysis telling you how the power system, and your plane, will perform.
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.
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.
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.
