Motors are considered the heart of drones, like engine is the heart of cars. Without a solid motor, no matter how many nice features a drone has, it’s not worth your money. Because at the end of the day you need it to fly and fly well. Direct Current(DC) motors has been used for years, from your disk player to electric cars. A major technological improvement in recent years has been Brushless DC motor.
Today we are going to example the difference between traditional brush motors and the new brushless motors, and advantage and disadvantage of each type of motors. Also we are going to example some best drone product in the market in 2018. We will pick a best option in each of the listed categories.

What is Brushless Motor?
Brushless motors are the new generation of DC motors. The advantages of a brushless motor over brushed motors are high power to weight ratio, high speed, and electronic control. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles. In drones typically, we want to choose brushless motor over traditional brush motors, because of it’s high energy efficiency and power to weight ratio.
Benefit of brushless motor?
The benefits are many folds. They last longer. They are more powerful. They are more durable and reliable, etc.
We have found an infographics to demonstrate the difference between the two types of motors.

How are we choosing the best drone?
Many factors goes into our evaluation of a drone before we make a final decision. They have different weight in our final decision. Some of the most important factors are:
It shows how much effort a company puts into it’s products. You are just tell from looking at a drone without looking at numbers and specifications too much. It is the foundation of everything else, such as flight control, camera quality, etc. Thus we don’t take a lightly.
How well a drone flies is crucial. Even if you are using the drone for shooting aerial photography, flight control is still as important as your camera. Because without a stable and steady flight control, your photos and videos will not be crisp and sharp.
We do take camera quality and feature into consideration. Aerial photography is getting more and more popular as it can offer a different vantage point versus traditional photography. Drone camera deserves special attention because they are limited in size and weight, so some drones were carrying really cheap and low quality cameras. So be careful when you choose a camera drone.
