[Official Japanese Product] Hitec Multiplex Japan RED ZONE XZ-105DR (10.5T) Brushless Motor, Official Japanese Product, XZ-DR Series, with Rotor Fan

Equipped with a rotor fan that provides excellent cooling and generates pleasant sound waves. Revolutionary structural design tunes the sound during high-speed turbo rotation. Dramatically reduces internal aerodynamic resistance at full throttle rate, reducing temperature rise at high output by 5% compared to conventional models. The special stator is made of 0.2mm thick laminated silicon plywood, achieving a conversion efficiency of 94%. A smooth 2-pole rotor has been developed that can withstand high-speed rotation even at temperatures of 200°C. High-heat resistant enamelled wire (1EI/AIW (H) grade) is used. An extra-large bearing beyond its class is used in the front end, achieving unparalleled low rotational friction. Its high load-bearing capacity extends durability. The front end is machined from A7075 (ultra-super duralumin), providing lightweight, high strength, and excellent heat dissipation. Sensor ports are located in two directions, allowing for a smart fit with the sensor cable wiring of each chassis. Gold-plated cable sockets are pre-soldered, allowing for easy wire connection and disconnection.
