The LIGPOWER Polymer Manual Variable Pitch Folding Propeller MF2211VP-2PCS/PAIR is an advanced 22.4*8 inch propeller designed for multi-rotor and VTOL drones. Engineered to enhance thrust capacity and operational efficiency, it features a reinforced propeller root for durability and adaptability under high pull conditions. The aerodynamic design, combined with a larger swept-back tip and downward curved winglets, optimizes tip vortex distribution, reducing energy consumption and vibration. This propeller is ideal for professional users who require rapid adjustments across multiple scenarios. It facilitates manual pitch adjustment with ease, thanks to the straightforward replacement of the positioning block, eliminating the need for additional tools. The commonly used pulling force range is from 0.5 to 2 kilograms, with a maximum pull force of 2.8kg when paired with the LIGPOWER MN4012 KV340 motor and FLAME 60A 12S V2.0 ESC.
