When buying replacement motors, keep in mind that the X5S has thicker and shorter motors (black rear and 8mm diameter) than the old X5 / X5C (7mm diameter and white rear). The camera, after playing for a day or two, must be removed. There is no FPV from it, the only thing you can see is what you are filming. And if you remove the protection of the screws and the camera, then an unprecedented maneuverability is formed and it somehow goes against the wind. Plus, the probability of hanging a drone on a tree is greatly reduced. It is better to lose a propeller or a motor than to hang it by the protection, and it clings to everything around like Velcro. And yet - there is a model with a barometric sensor, do not spare the extra penny and take it. For beginners, each such mode provides an opportunity to take a breath and gather your thoughts.
