## Long description

Gemfan 3-blade Race Copter Bullnose 5×4 inch (12.7×10.2 cm) propeller set is designed for multirotor drones that require higher thrust and responsive handling. The three-blade configuration increases the propeller disc area compared with two-blade designs, delivering stronger acceleration and improved mid-to-high RPM performance. These propellers suit pilots seeking precise control during racing and aggressive freestyle maneuvers on platforms that accept 5×4 three-blade props with appropriate mounting dimensions.
Advantages
The three-blade Race Copter Bullnose shape offers increased static and dynamic thrust while keeping vibration levels low for smoother flight characteristics. The compact 5×4 size balances agility and lift, enabling quick throttle response and stable hovering. Molded from a durable composite material, this propeller set provides consistent blade pitch and shape, which helps maintain predictable handling across flight regimes.
Suitable for
 FPV racing where rapid acceleration and tight cornering are required
 Agile freestyle flights with quick directional changes and punch-outs
 Multirotor test rigs and tuning sessions focused on throttle response and mid-range power
Key specifications
 Blade count: 3 blades per propeller
 Diameter: 5 inches (approximately 12.7 cm)
 Pitch: 4 inches (approximately 10.2 cm)
 Shape: Bullnose tip for responsive airflow and stable lift
 Material: reinforced composite suitable for high-RPM use
 Mounting: compatible with standard 5×4 three-blade mounting patterns (confirm hole/pitch fit for your motor)
How to use
Install the propellers on motors that match the propeller's mounting hole and pitch specifications, ensuring the correct rotation direction for each motor (clockwise or counterclockwise). Secure each propeller with the appropriate nut or screw and torque to the manufacturer's recommended value to prevent loosening in flight. Perform a slow spin check on the bench to confirm there is no contact with the airframe and that the blades clear nearby components. Balance propellers before flight if vibration is observed to improve flight smoothness and component longevity.
Usage recommendations
Use these propellers for short, high-performance flights such as race heats or freestyle sessions; verify motor and ESC thermal limits during aggressive throttle use. Replace any propeller that shows cracks, chips, or permanent deformation to maintain flight safety and consistent handling.
