Propellers 1270-3

Order powerful 1270-3 three-blade propellers for your heavy duty drone!

Provide your drone with a reliable and powerful propulsion system. The 1270-3 propellers are specifically designed for heavy duty multi-rotor applications including agricultural and cargo drones. The 304.8mm (12") diameter and 7" pitch provide excellent lifting power and efficiency when working with powerful motors. High-strength nylon material with glass fiber reinforcement ensures durability and resistance to shock and vibration.

• High strength material. Glass fiber reinforced nylon provides excellent rigidity, strength and resistance to deformation.

• Universal mount. A 6 mm diaphragm with an adapter ring allows you to install propellers on motors with 5 mm and 6 mm shafts.

• Optimal parameters. The 304.8 mm diameter and 7-inch pitch provide powerful thrust for heavy-duty unmanned platforms.

• Reliability in flight. Reinforced design and high-quality materials minimize the risk of blade destruction at high speeds.

• Three-blade design. Provides smoother operation, better stability and efficiency in hover mode.

Operating principle and aerodynamics

The 1270-3 propellers convert the rotation of powerful brushless motors into lift. The 304.8 mm (12 in) diameter captures a large volume of air, providing the necessary traction for lifting heavy loads and professional equipment. A 7" pitch means that per revolution the propeller theoretically moves 7" through the air, allowing for high efficiency at relatively low RPMs.

The three-blade design distributes load more evenly, reducing vibration and improving smooth operation, which is especially important for flight stability. The glass-reinforced nylon material gives the blades the stiffness needed to maintain geometry under high loads, but still retains enough elasticity to absorb shock.

Specifications and Compatibility

These propellers are ideal for professional drones with motors designed for 12-inch propellers. A universal 6 mm diaphragm with an adapter ring allows them to be used both on motors with a 6 mm shaft and on motors with a 5 mm shaft (using the included adapter).

They are widely used in agricultural spraying drones, cargo drones, and high-power aerial survey platforms where high reliability and payload capacity are required. Proper operation requires the installation of both left- and right-hand rotation (CW/CCW) propellers.
