When you are ordering the HR iCAMERA4 H4 drone, you will find that it comes in two versions. The first one comes with brushless motors. The second version has coreless brushed motors.
The one with the brushless motors will cost you more money than the one with the coreless motors.
Most people ask: Which is better: a coreless motor or brushless motor drone?
Well, brushless motors are definitely better since they do not have brushes or commutators. As a result, such motors can last longer, give a more powerful performance, and they do not overheat.
The coreless motors are brushed. Thus, they might overheat when you fly the drone for too long.
You will also choose whether you want to buy the drone with one, two or three batteries. Of course, the package with two or three batteries will cost more money. But it is worth it because you will get a longer flight time.
