This is quite simply as it says in the title. I have put together a little chart that will show you how many watts of power you need from your motor to equal the power of your two-stroke motor…
Remember, to work out the watts we multiply the continuous current of the motor by the number of volts going in. So when you look at this table, divide the number of watts by the battery you intend to use and that will tell you what sort of amps your motor is going to have to draw to get there.
Clear as mud? On with the chart then…

Hopefully this will give you some idea when it comes to choosing an electric motor for your model.
Will this make any difference wether Glow or diesel? How does it relate to the equivalent Kv rating too?
