26 x 8.5 Two-Blade Drone Propeller

26 x 8.5 Two-Blade Drone Propeller

The G26 x 8.5 Two-Blade Composite Plastic Propeller is designed for professional drone applications requiring high lift and energy efficiency. The 26 in the product name refers to the propeller diameter, and the 8.5 refers to the pitch.

The large 26-inch propeller diameter helps create strong airflow at low and medium speeds. The 8.5-inch pitch ensures a balanced flight performance between lift and power consumption. The two-blade design generates lower air resistance compared to three or more blade models and, when combined with a suitable motor system, contributes to more efficient flight times.

The propeller's epoxy resin-reinforced composite plastic material supports the preservation of the blade shape under high torque. The fact that a single blade weighs approximately 68–73 grams helps keep the rotational mass under control for a large-diameter propeller.

Applications
Agricultural Drones
The G26 x 8.5 drone propeller is preferred in professional UAV systems used in agricultural spraying, fertilization, and seed planting operations. In agricultural drones with large tank capacities, it provides high lift force when combined with suitable motor and electronic systems.

Main agricultural application areas:

Agricultural spraying drones
Liquid and granular fertilizer application systems
Seed planting drones
Plant protection operations
Long-duration field flights
Tank systems in the 20–30 kg payload class
The stated carrying capacity may vary depending on the total number of motors, body structure, battery system, and motor performance of the drone.

Industrial UAV Systems
The 26 x 8.5 twin-blade propeller can be used in heavy-duty industrial drones and long-range unmanned aerial vehicles.

Power line inspections
Infrastructure and facility checks
Heavy-load logistics operations
Cargo-cargo multicopters
Long-range VTOL platforms
Mapping and surveying UAV systems
Custom-made industrial drones
Professional Filming and Research
The wide-diameter propeller structure is also a suitable option for professional platforms carrying heavy camera and sensor systems. It helps create balanced lift force in drones carrying large cameras, gimbals, lidars, or scientific measurement equipment.

Professional cinelifter drones
Multicopters carrying large camera systems
Scientific research UAVs
Photogrammetry drones
Mapping systems
Platforms carrying lidar and special sensors

Advantages of Two-Blade Design
Two Blade propellers are frequently preferred in professional drone systems aiming for energy efficiency and long flight times. A lower blade count can help reduce air resistance in suitable motor and fuselage configurations.

The main advantages are:

Efficient airflow
Low rotational weight
Controlled power consumption
Suitable for long-duration flights
Compatibility with high-torque motors
Balanced lift performance
Effective operation at low and medium speeds
Suitable design for large UAV platforms
Motor Compatibility
The G26 x 8.5 propeller can be used with high-torque motor systems such as the T-Motor G series and Hobbywing HV8014. However, motor compatibility should not be determined solely by brand or model name.

The following technical specifications must be checked before assembly:

Motor KV rating
Maximum motor power capacity
Recommended propeller diameter
Battery voltage
ESC current capacity
Motor shaft and mounting hub
CW and CCW rotation direction
Total takeoff weight of the drone
Distance between motors
Motor and propeller combinations not recommended by the manufacturer may cause overcurrent, high motor temperature, or ESC damage.

Thrust Capacity
The thrust that a G26 x 8.5 propeller can provide can vary between approximately 4.5–19 kg depending on the motor and power system used. The stated value represents the approximate operating range achievable for a single rotor.

Factors affecting actual thrust performance:

Motor KV value
Battery cell count and voltage
ESC capacity
Propeller speed
Air temperature
Altitude and air density
Total weight of the drone
Propeller balance
Motor and propeller compatibility
Wide Operating Temperature Range
The propeller has a material structure suitable for operating conditions between -40°C and +65°C. This wide temperature range provides an advantage for agricultural, infrastructure inspection, and industrial operations carried out in different climatic conditions.

However, the operating limits of the battery, motor, and electronic components at very low or high temperatures should also be checked.
