To create motor profile you need motor constants. Motor constants can be measured or calculated, last one requires a lot of input parameters. But most motor manufactures specify motor constants, which they obtain from testing, while during design phase they use calculation to figure out how to create one with parameters they type into model.
To create graphs you need motor Kv, I no load, I max, Resistance. To create more sophisticated graphs you need to add inductance, inertia and core parameters. But for RC applications the first 4 constants will do the job of defining efficiency, power, torque and current draw.
As reference you can check any motor manufacture datasheets for motors or even Lehner excel spreadsheet where you can click on cell and check for math behind. I was trying to bring all motor data under one roof :)
