High-Efficiency Propulsive Performance & Dynamic Balance for Commercial UAVsDesigned for mid-sized commercial quadcopters, aerial mapping drones, and industrial inspection UAVs, the T-MOTOR NS15×5 Carbon Fiber Propeller Set (2PCS/PAIR) delivers optimal aerodynamic efficiency and rock-steady flight stability. Combining a 15-inch diameter with a 5-inch pitch, this propeller pair generates high static thrust at lower operating RPMs, directly reducing power draw on 4S to 8S setups. Crafted from premium high-modulus carbon fiber composite, the NS series offers exceptional structural stiffness to eliminate blade distortion during rapid throttle bursts while keeping rotational weight minimal for precise flight controller PID response.
Universal Commercial UAV Fit: Compatible with 4S–8S survey quadcopters and industrial multirotors.

Packing List
Before using this product, please check whether all the items listed above are included in the package. If anything is missing, please contact our online customer service or email us at online@mepsking.com.
Note
1.Please make sure that screws of cover plates are mounted well.
2.Do not add force onto the propellers,
3.Fall-off or experience equivalent impact to propellers will lead to deformation or cracks. in this case, you will need
to replace them with good ones.
4.NEVER decompose the propellers. Decomposition of which will result in safety issues. Do not use the propellers in
hostile environments containing H20,S02,N02,Cl2,organosilicon,cyanogroup and phenol.
5.Keep the propellers away from the mentioned environments in (4)
6.For long time storage of over 6 months, please keep it in sealed preservation.
FAQFeel free to ask us any questions
Q: What motor sizes and battery voltage setups work best with the NS15x5 propeller pair?
A: The NS15×5 propeller set is optimized for 40xx to 50xx stator size motors, such as the T-MOTOR MN4014, MN501-S, U5, or U6 series operating on 4S to 8S LiPo/LiHV power setups. Always verify your motor’s thrust testing data chart to keep continuous current within safe ESC limits.
Q: What are the primary advantages of using solid carbon fiber props over plastic or nylon props?
A: Solid carbon fiber propellers offer significantly higher structural rigidity and lower rotational inertia. Under sudden acceleration or high-speed maneuvers, carbon blades maintain an accurate pitch angle without flexing, resulting in crisp throttle response, lower acoustic noise, and higher power efficiency.
Q: Does this 2PCS/PAIR package include both Clockwise (CW) and Counter-Clockwise (CCW) propellers?
A: Yes, the product package comes as 1 Pair (2 Pieces total), containing 1 Clockwise (CW) propeller and 1 Counter-Clockwise (CCW) propeller, ready for mounting on standard multirotor motor caps.
Q: How does factory dynamic balancing improve flight performance and HD video quality?
A: Unbalanced propellers generate micro-vibrations that transfer through the airframe, causing video "jello" artifacts and introducing noise into flight controller gyroscopes. T-MOTOR’s factory dynamic balancing eliminates high-frequency vibration, extending motor bearing lifespan and ensuring clear payload footage.
Q: How should I properly secure the NS15x5 propeller onto the motor shaft?
A: Use the dedicated prop cover plate and structural bolts supplied with your motor. Torque the mounting bolts evenly in a cross pattern to seat the carbon hub flat against the motor top cap without over-tightening.
