Experience the perfect fusion of durability and efficiency with the Sunnysky X-Series V3. The X2820-7 800KV is widely recognized in the RC community as a “workhorse” motor, known for its remarkably smooth operation and high thrust-to-weight ratio.

Sunnysky has utilized CNC-machined 6061-T6 aviation aluminum with a specialized hollow design to ensure maximum heat dissipation, allowing you to push your aircraft to its limits without thermal throttling. Inside, the motor features hand-wound copper coils, a premium detail that ensures tighter packing and higher efficiency compared to standard machine-wound motors.

Why the X2820 Stands Out:

Industrial Grade Internals: Equipped with imported Japanese NMB bearings, providing a whisper-quiet flight and significantly extending the motor’s service life.
Rugged Steel Shaft: The heart of the motor is a heat-treated 420 stainless steel shaft, designed to resist bending during hard landings or high-G maneuvers.
Versatile Power: Rated for 3S to 5S LiPo, this motor is incredibly flexible. Use 3S for efficient sport flying or 5S for “locked-in” high-torque aerobatics.
Balanced Performance: Each motor is factory-balanced to minimize vibration, protecting your electronics and ensuring crystal-clear FPV footage.
