CB2 PRO 28x9.2 in D10-D20(M3x4) 1 Pair Carbon Fiber Propeller CW CCW Drones Props for Multicopter Quadcopter Hexacopter RC DIY Hobby

Excellent control performance. Light weight. Low inertia. Perfect for explorations and inspection applications etc. Propeller design optimized through flight testing to improve thrust efficiency. Mounting holes compatible with most multi-rotor motors on the market. Sturdy and lightweight propeller body with excellent consistency and superior dynamic balance characteristics. Each pair include: Carbon fiber forward propellerX1 /Carbon fiber reverse propellerX1

• 12K Carbon Cloth. Excellent fatigue resistance and higher strength
• The wing shape is carefully optimized to effectively reduce air resistance and improve thrust and efficiency. Increase 5%
• The matte surface can reduce the friction between the propeller and the air, reduce flight noise, and make the flight quieter. Decrease 3%
• Single propeller weight 72g, Common speed range 2800~3900RPM Common thrust range 4.5-9kg, Working Temp -40~65 ℃, Storage Temp -10~50℃
• The use of ultra-light carbon fiber material significantly reduces the weight of the propeller, this reduces the moment of inertia and improves the aircraft's response speed and control flexibility
