T-MOTOR U8 KV135 High-Efficiency Brushless Motor for Professional Multi-Rotor Aircraft

T-MOTOR U-Power U8 KV135 is a high-performance brushless motor specifically designed for professional use on multi-rotor aircraft such as hexacopters and octocopters, especially where high efficiency is required, and in dirt contaminated environments, wet-weather, and extreme climate conditions. U-series motors feature extra-large bearings made in Germany. These motors are water and dirt resistant. MTBF (Mean Time Between Failure) is 160 hours, over 2.5 times competing motors. With epoxy-coated silicon-steel stator laminations for low eddy current loss, oxygen-free copper windings for low resistance, and N45UH high-temperature Neodymium magnets, U-series motors are highly efficient and can maintain good performance even up to 180° C. This U8 135KV motor is recommended for use with 6S LiPo and 26x8.5 to 29x9.5 CF props. This motor can power Hexacopters of 15-kg total takeoff weight, or Octocopters of 20-kg. Recommended ESC is T-MOTOR T30A-Pro or T40A. T-MOTORs are backed by a two-year manufacturer's warranty on materials and workmanship.
