The iFlight Xing 2814 1100Kv is a large motor designed for long-range drones or Cinelifters. The Xing uses a bell made of durable 7075 aluminum alloy, high quality NSK 11x5x5 bearings, N52H round magnets as well as a bolt-on shaft mount. All of these features make the iFlight Xing motor one of the best on the market. We recommend using the motor with an 8-9" propeller and 6S battery for high thrust or with a 9-10" propeller and 4S battery for good efficiency.
