The Gemfan 51466 MCK V2 is a high-quality 5-inch three-blade propeller designed for professional FPV racing. Made of durable polycarbonate (PC), it features a 3.6-inch pitch, 131.8 mm diameter, and weighs just 4.2 g.
The updated V2 version is 20 % more durable due to an improved blade design. It provides more thrust, faster acceleration and higher top speed, while maintaining precise control. The propeller is compatible with 2207-2306 and larger engines, making it perfect for pilots seeking maximum performance on challenging courses and using high-KV engines.
Features:
• Increased durability
The updated V2 design is up to 20% more durable than previous versions, making the propeller better able to withstand impacts and heavy use during racing.
• Optimized performance
The 3.6-inch pitch and improved blade geometry provide strong thrust, fast acceleration and high top speed while maintaining precise control.
• Quick response
The lightweight design, weighing just 4.2 g, reduces rotational inertia, so the propeller responds quickly to throttle changes and ensures better maneuverability.
• Balanced management
The three-blade design provides an excellent balance of thrust, stability, and control precision, making the propeller suitable for both FPV racing and high-speed freestyle flights.
• Wide compatibility
The standard M5 mounting hole allows the propeller to be used with 2207-2306 and larger motors, ensuring reliable installation and stable operation.
