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.

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.(For a more in-depth tutorial, please visit The following is an overview of the steps that will get you well on your way to using Moto Calc to help choose a power system for your model: Based on the results above, either go back to step 1 and select a different suggestion, return to step 2 and modify some of the suggested components, or install the recommended power system in your plane and go fly!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 last line of the summary, labeled "Stats", summarizes the predicted performance of the model.
