I picked up my tablet that was next to my drone but as I picked up the tablet it got caught under one of the drone's propellers so the drone got lifted slightly and then fell back onto the shelf. It only fell from about 2 centimeters but when I looked at the motor I noticed that the gap in between the motor and frame is slightly bigger than on the other motors, and this same motor also has a bit more resistance when spinning it by hand. Is it really possible that I damaged my drone because it fell from 2 centimeters or is this just a coincidence, and is it normal for the gaps to not be the same?
