About carbon fiber propellers that you should know !! Advantages: 1. Carbon fiber accessories produce fewer vibrations due to their rigidity, and they seem quieter than plastic propellers. 2. They are lighter and much more resistant than plastic when crushed, but not indestructible. 3. Light accessories mean less inertia, therefore a faster engine change change, and control is more reactive. Disadvantages: 1. Due to various production processes, the surface of the carbon fiber propeller can have scratches during the production process, which is not as smooth as the plastic propeller, 2. Carbon fiber accessories have a slightly shorter flight time than plastic accessories of the same size/not. If that bothers you, please don't buy! Characteristic A pair of blades (a positive and a reverse) a drone needs 2 pairs of blades (2 positive 2 inverted), Different models cannot be used in combination with other blades Because each blade design structure is different, if you need to recommend 2 pairs at the same time. Golden triangle wing design for higher aerodynamic efficiency Fiber material Super resistant carbon to reduce the damage caused by the impact on the blade Description Weight: 24g (pair) Product size: 19.5x12cm (Simple) List packaging as shown in the photo Note does not understand the drone
