The 12x12 EP Composite Plastic Propeller is a high-pitch propeller model developed for electric fixed-wing UAV systems, aircraft with pusher motor configurations, and twin-engine platforms with reverse rotation.
Its aerodynamic structure, with a diameter of 12 inches and a pitch of 12 inches, is suitable for projects that prioritize high flight speed, powerful acceleration, and high cruising performance over hovering performance. The EP type reverse rotation design can be used in pusher configurations with the appropriate motor and mounting system.
The numbers and letters in the 12x12 EP product name indicate the basic characteristics of the propeller:
12 inches: Total diameter of the propeller.
12 inches: Pitch.
E: Indicates the propeller class developed for electric motors.
P: Indicates reverse rotation in pusher or electric systems.
Therefore, it should not be confused with standard multirotor propellers produced in 12x12 EP, 12x4, 12x5, or 12x6 sizes. In manufacturer nomenclature, multirotor propellers are classified as “MR”, and counter-rotating multirotor propellers as “MRP”.
The 12x12 EP Two-Blade Composite Plastic Propeller is designed for electric aircraft projects requiring high forward thrust. Its 12-inch diameter corresponds to approximately 304.8 millimeters. The high pitch of 12 inches helps create a stronger forward airflow with each rotation.
High-pitch propellers particularly support the cruising and acceleration performance of fixed-wing aircraft. However, they can place a greater load on the motor than low-pitch propellers. Therefore, motor, ESC, and battery selection should not be based solely on propeller diameter.
The high-strength composite plastic construction offers a balanced performance between mechanical rigidity, controlled flexibility, and low weight. When used with proper balancing and centering, it can help control vibration and efficiently transfer engine power.
Which Aircraft Use It?
12x12 EP propellers are primarily used in electric aircraft that perform forward flight.
Main areas of application:
Pusher-driven fixed-wing UAV systems
Electric model aircraft with pusher configuration
Twin-engine aircraft with inverted rotation
Long-range reconnaissance and surveillance UAVs
Mapping and photogrammetry aircraft
Infrastructure and terrain inspection platforms
Speed-focused custom UAV projects
Advanced flight engines for VTOL systems
Electric research and development aircraft
Electric pusher propellers can be designed to meet the inverted rotation requirement in twin-engine tractor systems or for use in a true pusher configuration. In a true pusher installation, the correct face of the propeller must be facing the direction of flight.
Is it Suitable for Use in Multicopters?
12x12 EP is not a standard quadcopter or hexacopter propeller. In manufacturer classifications, the EP model is intended for electric pusher and reverse rotation applications, while the MR models are directly aimed at multirotor systems.
While it might be possible to use it with technical tests on a custom-designed multicopter, it cannot be said to be directly compatible with a DJI F450, Tarot 680, or similar body. The high pitch value can increase motor current and electronic component temperature during hovering.
Before use in a multicopter project, the following tests must be performed:
Static thrust test
Motor current measurement
Motor temperature control
ESC temperature control
Propeller balance test
Vibration measurement
Full load flight test
Emergency landing test
