Durable Polymer Construction & Compact Folding Mechanism for Mid-Sized UAVsEngineered for mid-sized commercial multirotors, security inspection quadcopters, and aerial mapping platforms, the T-MOTOR MF1907P Polymer Folding Propeller Set balances high propulsive efficiency with field-tested crash durability. Featuring a 19-inch diameter paired with a 7-inch pitch, this propeller set utilizes an advanced engineered polymer composite that offers high impact resistance while keeping rotational weight low. The modular folding design allows drone arms to collapse neatly for transport and protects motor shafts during rough landings, making it a reliable power companion for daily commercial missions.

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 are the key advantages of engineered polymer folding props compared to full carbon props?
A: Engineered polymer composite propellers are more fracture-resistant and cost-effective than full carbon fiber props. If the drone touches down roughly on uneven terrain or strikes grass, polymer blades flex slightly to absorb impact without snapping instantly, protecting expensive motor shafts and arm mounts.
Q: What motor sizes and voltage setups work best with the MF1907P propeller set?
A: The MF1907P is optimized for 40xx to 50xx stator size motors, such as the T-MOTOR MN4014, MN501-S, U5, or U6 series running on 6S to 8S LiPo setups. Always check your motor’s thrust test table to keep current levels within safe ESC limits.
Q: How tightly should I tighten the pivot bolts on the polymer folding blade root?
A: Tighten the pivot shoulder bolts so that the blades move smoothly without axial play, but remain loose enough to swing freely under light hand pressure. Do not lock the bolts rigidly; the blades rely on centrifugal force during motor acceleration to unfold automatically.
Q: Does this product package include both Clockwise (CW) and Counter-Clockwise (CCW) propellers?
A: Yes, the package comes as 1 Pair (2 Pieces), containing 1 Clockwise (CW) propeller set and 1 Counter-Clockwise (CCW) propeller set, complete with matching folding prop adapters/hubs where applicable.
Q: Can I replace just one damaged polymer blade if it gets scratched or chipped?
A: While individual replacement blades can physically be mounted, we strongly recommend replacing folding blades in factory-matched pairs. Factory blade sets undergo precise dynamic balance pairing; replacing only one side can introduce micro-vibrations that degrade flight controller performance and camera stability.
