Brushless Outrunner, Kv. The higher the number, the more powerful it will be. You'll also need to make sure to specifically check how many Amps that a motor pulls in order to find the right Electronic Speed Controller ESC. If you have a motor that pulls 20A, a 30A speed controller would work fine.
Much of the time, you can how much thrust a certain motor produces with various propeller and battery combinations.
This information can be used to find the perfect sized motor for your model. If you want to go vertical with a model that weighs 2lbs, make sure to get a motor that produces over 2lbs of thrust. Choosing motors can be a little challenging and confusing at first, but knowing what these numbers and statistics actually mean can help a lot.

Size The physical size of a particular brushless motor is usually indicated by a number that looks like this - ' '. Power The overall power of a motor tends to be indicated by Watts. Thrust Much of the time, you can how much thrust a certain motor produces with various propeller and battery combinations.

If Cobra listed its motor using this naming convention, it would be roughly , so they are roughly the same size. Comparing the weights, the Cobra is grams and the SK3 is grams. With similar Kv, weight, and size, the motors are nearly the same. If a kit calls for a certain size, find out whether the manufacturer means stator or motor case dimensions.
Define your requirements for the airplane and do some simple math to figure out the right motor to use. This is a basic course to get you going successfully. Down the road we can look more closely at details. Thank you for your comments on motor Kv. It is a secondary information in motor selection process. The first thing as you pointed out is required power capabilities. Unfortunately many if not most manufacturers specify motor dimensions and Kv. Nothing about power capability.
Sadly even most articles about electric motors and reviews of electric powered models mention Kv like a prime consideration. Hopefuly more people will read your article. For years I have been flying with Graupner direct drive speed and brushed motor on 6 and 7 NiCad cells. Weighing 38 oz to 55 oz Playboy and Lanzo Bombers as examples. I like the silence of these brushed motors but like the prop noise.
Also, don't like the heavy ni-cads and poor reliability and life expectancy of the brushed motors. I need to change all to brushless. Great article! Clears up all the long standing questions I had. You are right, long time flyers will get into the weeds faster than a plane into a solitary tree.
It might have been useful to mention the definition for stator and rotor magnets. The part with the wire wrapped around is the field. The field is used to control the motor by adjusting the energy applied. My figures show that I want about 25 watts to power my project. Wish you had some data and motor types that fit the range. It is a simple addition, but I think it would help if there was a bit more talk about ESCs and how they are chosen.
You talk about amps, very clearly, but if you are looking for the right ESC, one has to know that Amps are essentially way to choose the proper ESC. And further, what are the consequences of choosing the wrong size ESC - what happens. It may seem "too" rudimentary, but for the novice, I think it would help. Great article!! I have spent decades in the electronics industry. I get what your tying to say.
However, there is so much not delineated in this article that no normal person could follow it. I am new to electric planes and this will make it better for me to understand.
Hobby King has motors listed as "40 size", which is very helpful. And now I know what kv means. This is a great article that does well at explaining what the key terms are and how to select a motor. The bottom line you point out is that we need to know the wattage and Kv that would best fit our desired model weight giving a selected prop and RPM. However where you and nearly all brushless motors suppliers fall short and have for at least a decade is that motors aren't listed by wattage, only by Kv.
Sure, wattage is sometimes made available, but only by digging through data sheets. In my opinion, wattage is the primary sorting criteria for motor selection. If you could publish a database of brushless motors that includes wattage as a data point, that would truly be useful!
Thank you for very good article about electric motor basics and how to choose one. I suggest a companion article about choosing the proper electronic speed control ESC. This is a great article. As im new to the hobby i would like more articles like the explaining how to size servos , esc, for someone who wants to build foam or home built planes.
