## Description

Item name: 2x 10x4.5" 1045 cw ccw nylon propeller for hex rotor hexa multi copter orange. These high quality carbon fiber propellers work much better than the stock propeller, the stock props or non-carbon fiber props are soft that they cause "jello effect", carbon fiber props are lighter and much stronger (you'll know the difference when you get them).

Review: Don't buy different from images , not fit in your machine - It is not same as shown in image, it's nob is different from the image ,do not buy it
