Alternatively, you might just slightly revise the current suggestion by making changes in the Moto Calc Workbench window, perhaps trying different propeller sizes, more or fewer cells, or a different gear ratio (step 2).Or, if you had specified any ranges in step 2, you can select a different result from the static analysis and generate a new in-flight analysis (step 3).

If you are a newcomer to electric flight, Moto Calc's Moto Wizard will ask you a few simple questions about your model and your preferences (such as brand of motor), and will then make suggestions as to the ideal power system.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.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.After a few iterations, you should have narrowed down your choices to a few power systems suitable for your model and your requirements.

At this point, it's time to install some equipment, and go flying.

Moto Calc can also do an in-flight analysis for a particular combination of components, predicting lift, drag, current, voltage, power, motor and electrical efficiency, RPM, thrust, pitch speed, propeller and overall efficiency, and run time at various flight speeds.

It will also predict stall speed, hands-off level flight speed, throttle, and motor temperature, optimal level flight speed, throttle, and motor temperature, maximum level flight speed, rate of climb, and power-off rate of sink.

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.

These five steps are described in more detail below.
