1045 Multirotor Propeller

Specifications

The 1045 RC Propeller is a high-efficiency aerodynamic blade designed for maximum lift and stable flight. Its 10-inch diameter makes it the "gold standard" for mid-to-large-sized DIY drones and RC aircraft.

Core Highlights

High Thrust Output: Engineered to provide substantial lift, making it ideal for quadcopters carrying extra weight like cameras, GPS, or larger batteries.
Aerodynamic Balance: The 10-inch diameter and 4.5-inch pitch offer a perfect blend of high-speed efficiency and stable hovering.
Vibration Control: Constructed with a rigid airfoil design to minimize "blade flutter" at high RPMs, which helps prevent the "jello effect" in aerial videos.
Universal Compatibility: Features a center hub that fits most standard brushless motors (like the A2212 series). Most sets include adapter rings to fit motor shafts from 3mm to 6mm.
Impact-Resistant Build: Made from high-strength ABS plastic or Glass-Fiber Nylon, ensuring the blades can survive minor collisions or rough landings.

Product Details

This 1045 RC Propeller is a high-efficiency aerodynamic blade designed specifically for multirotors, quadcopters, and fixed-wing RC aircraft. With its 10-inch diameter and 4.5-inch pitch, it provides the perfect balance of high lift and stable flight performance, making it a favorite for both beginner pilots and intermediate hobbyists.

The propeller is engineered with a rigid airfoil shape that minimizes flexing during high-RPM maneuvers, ensuring consistent thrust and reduced vibration.

Detailed Product Features

Optimal Performance: Specifically tuned for mid-sized drones (like those using the F450 or F550 frames). The 4.5" pitch allows for responsive acceleration and precise control during hovering and flight.
High-Durability Material: Manufactured from high-quality ABS plastic or Nylon, providing a lightweight yet tough construction that can withstand minor impacts and high centrifugal forces.
Precision Balance: Each blade is factory-molded for high symmetry to minimize "jello" effects in aerial videos and reduce wear on your motor bearings.
Universal Compatibility: The center hub is designed to fit most standard brushless motors (like the popular A2212 1000KV series). It usually includes a set of adapter rings (spacers) to accommodate different shaft diameters (3mm, 4mm, 5mm, 6mm, etc.).

Technical Parameters

Diameter: 10 inches (approx. 254mm).
Pitch: 4.5 inches.
Rotation Options: Available in CW (Clockwise) and CCW (Counter-Clockwise) to provide the counter-torque needed for stable multirotor flight.
Hub Thickness: ~8mm.
Weight: Approximately 10–12 grams per blade.

Common Use Cases

Custom Drone Builds: The standard propeller for DIY quadcopters used in hobby flying or university engineering projects.
Aerial Photography: Provides the smooth, steady lift required for carrying small action cameras or FPV (First Person View) gear.
RC Airplanes: Used as a tractor (front-mounted) or pusher (rear-mounted) propeller for park flyers and slow-flyer planes.

Maintenance & Safety Tip

Always check your propellers for small cracks or "white stress marks" before every flight. A damaged propeller can fail mid-air, leading to a crash. It is recommended to use a propeller balancer for the smoothest possible flight experience.
