Sunnysky X2820 800kv Brushless Motor
by SunnySky

Enhance your UAV, RC plane, or drone performance with the Sunnysky X2820 800kv Brushless Motor—a superb choice for hobbyists and professionals seeking reliable power. Designed with CNC-milled hollow construction for optimal heat dissipation and weight reduction, this motor delivers excellent torque and efficiency in model aircraft, multirotor, and FPV builds.

The 420 stainless steel shaft (imported from Japan) undergoes heat treatment for increased strength and bending resistance, while the 6061-T6 aviation aluminum alloy top and bottom caps ensure durability without compromising weight. Equipped with imported NMB bearings, the X2820 provides quiet, stable, and long-lasting operation. Each coil is hand wound for tight, neat, and efficient winding, boosting continuous power output.

Whether you’re configuring an aerobatic airplane or a 3D aircraft, this high-quality brushless drone motor offers the thrust and reliability demanded by enthusiasts. Recommended for 3–5S LiPo setups and capable of handling a continuous current of 46A with up to 700W of power, the Sunnysky X2820 800kv is the ideal RC plane motor to propel your projects forward with confidence.
