Propellers www.sunfounder.com
There are CW and CCW propellers too. How to tell them apart?
Place the propeller on a flat surface, check the curved side of the blades. As we can see, the left one with the curve brim at the right
side is a CW propeller, when the right one with the curve brim at left is a CCW one.
When mounting the propellers, ensure the two diagonal propellers are of the same type. And the rotating direction of the motor and of
the propeller onside should be matched, i.e. if the motor is a CW one, the propeller will be a CW one too, and vice versa.
