Electric brushless motors for drones and RC airplanes. A simple topic, right? OK, maybe if you a few years in the hobby. But if you are only starting, you might have at least a few questions. In this video let's discuss some basic (beginner to intermediate level) aspects of brushless electric (BLDC) motors used in RC hobby to drive drones and airplanes

how to measure the motor size
what is KV and how it correlate to rotation speed
motor torque
motor KV vs torque how KV changes torque and how it correlates with another motor constant: KT
stator and rotor what is what and it's named like that
number of coils and poles 12N14P etc
does motor care about rotation direction
how to change the rotation direction of a motor
mounting holes spacing: 16x19 and 16x16 motor holes pattern
how not to fry your motor right away
