12x4.5 inch 1245/1245R Propeller Pair (CW+CCW)

The 12 - 4.5 inch 1245/1245R Propeller Pair (CW+CCW) is specifically designed for use in twin and multiple-motor RC airplanes or coaxial RC helicopters. This set includes two propellers, one rotating clockwise (CW) and the other rotating counter-clockwise (CCW), providing a matched counter-rotating pair for optimal performance.

  Key Features:  

• Counter-Rotating Pair: Includes one propeller rotating clockwise (CW) and one rotating counter-clockwise (CCW), ensuring balanced and stable flight performance in twin and multiple motor setups.
• Propeller Size: Each propeller measures 12 inches in length with a pitch of 4.5 inches per revolution, offering efficient lift and thrust for various RC aircraft applications.
• Compatible Motors: Suitable for use with brushless motors with an 800-2200 kV rating, offering versatility for different flight requirements. Low kV motors provide smooth flights with longer flight times, ideal for FPV and aerial photography, while high kV motors offer fast flights perfect for acrobatic maneuvers.
• Material: Made of high-quality plastic with an epoxy resin cover, ensuring durability and reliability during flight.
• Plastic Reducers: Comes with a set of plastic reducers in various sizes (2.75, 3, 3.17, 4, 4.70, 5, 6, 6.25 mm), allowing for compatibility with different motor shaft diameters.
