Description

The OrangeRX HD 1245 propellers are engineered for multirotor drones requiring reliable and efficient thrust. The 12×4.5 configuration provides a favorable lift-to-power ratio, making them suitable for aerial photography platforms, agricultural drones, and other heavy-lift applications where consistent performance is critical.

Manufactured from high-grade ABS plastic, these propellers achieve an optimal balance between rigidity for power transfer and flexibility to absorb minor impacts. The design incorporates an aerodynamic airfoil profile to enhance flight stability and reduce power consumption during sustained operation.

Key Features

  • High-Durability ABS Construction: Provides excellent impact resistance and long service life under typical flight loads.
  • Optimized Aerodynamic Profile: Blade design improves efficiency and reduces vortex-induced vibration for smoother footage.
  • Complete Reducer Kit: Includes six plastic adapters (3mm, 3.17mm, 4mm, 5mm, 6mm, 8mm) for universal compatibility with various motor shaft sizes.
  • Matched Pair Precision: Each CW and CCW propeller is manufactured to tight tolerances for balanced thrust and reduced vibration.
  • Epoxy Resin Reinforced Hub: The central hub is strengthened to withstand high torque and prevent splitting at the mounting points.

Applications

  • Aerial photography and cinematography platforms (e.g., heavy-lift hexacopters, octocopters).
  • Agricultural and crop-spraying drones requiring efficient, high-thrust propellers.
  • Large-scale DIY multirotor builds for payload carrying and long-endurance flights.
  • Educational and research drones where durability and consistent performance are prioritized.

Frequently Asked Questions

What motor shaft sizes are these OrangeRX 1245 propellers compatible with?

The propellers feature a 9.5mm central hub. A full set of plastic reducers is included for compatibility with 3mm, 3.17mm (1/8"), 4mm, 5mm, 6mm, and 8mm motor shafts. Ensure the reducer is snugly fitted to prevent vibration.

Are these propellers suitable for 6S or high-RPM drone racing applications?

No. The OrangeRX HD 1245 propellers are designed for efficiency and thrust on larger, slower-rotating multirotors (often using 4S-6S batteries). They are not optimized for the high RPMs and rapid directional changes of FPV racing. They are best for aerial photography, agriculture, and heavy-lift platforms.

What is the weight and pitch of each propeller?

Each propeller has a 12-inch diameter, a 4.5-inch pitch, and weighs approximately 28 grams. The 4.5-inch pitch provides a good balance of thrust and efficiency for stable, controlled lift on medium to large drones.
