JP 6x3 Microspeed 400 Propeller 6x3 (152x76) Hexless Hub

The JP 6x3 Microspeed 400 Propeller (Part No: JPDP4460310) is a performance-oriented propeller designed for high-RPM applications, particularly optimized for "400-size" brushed or brushless motors. Unlike the "Slow Fly" series, the Microspeed line features a stiffer, more aerodynamic blade profile intended for faster park flyers and pylon-style models where airspeed and efficiency are prioritized over static thrust.

Key Features:

• Microspeed Aerodynamics: Designed with a narrower blade chord and stiffer material to prevent blade deformation at high rotational speeds, ensuring consistent pitch delivery.
• Hexless Hub Design: Features a smooth internal bore (Hexless) which provides universal compatibility with collet-style prop adapters and O-ring prop savers commonly found on modern outrunner motors.
• 400-Size Optimization: Specifically pitched and balanced to complement the power curve of Speed 400 motors, offering an ideal blend of speed and current draw.
• Lightweight Construction: Minimizes rotational inertia for rapid throttle response, crucial for high-speed maneuvering and racing.

Pro-Flight Tip:

When using the 6x3 Microspeed on a high-KV brushless motor, always perform a static "amp-draw" test with a watt meter. The 3-inch pitch is relatively shallow, which allows the motor to spin up quickly; however, if you are upgrading from a smaller prop, ensure your ESC can handle the increased load. Pro-Tip: Because these props are often used on faster models, double-check that your prop saver O-rings are in good condition to prevent the propeller from departing the shaft at full throttle.
