SunnySky XS High Power X4110S Brushless Motor 340KV
by SunnySky

The SunnySky XS High Power X4110S 340KV is a precision-engineered brushless outrunner designed for high-efficiency, long-endurance multirotors and specialized industrial sUAS. As the lower-KV variant in the X4110S lineup, the 340KV model is specifically optimized for spinning larger propellers with greater torque at lower RPMs, making it the premier choice for heavy-lift platforms that require maximum flight time and stability. Built with Japanese NMB bearings and high-grade oxygen-free copper windings, this motor ensures smooth power delivery and reduced vibration for mission-critical aerial applications.

Housed in a semi-enclosed CNC-machined aluminum chassis, the X4110S 340KV features advanced ventilation and heat dissipation pathways that prevent overheating during sustained high-load operations. Its high-efficiency stator design and low-profile form factor provide a robust propulsion core for professional cinematography, agricultural mapping, and tactical reconnaissance. By prioritizing efficiency and reliability, SunnySky has created a motor that meets the rigorous demands of both commercial sUAS operators and university aerospace research labs.
