The integrated design of the ESC makes the overall volume is only the size of 550 motors, and the overall weight is only 210g, which makes the layout and wiring of the car frame simpler and more beautiful, perfectly solves the difficulty of wiring due to the small internal space of the rock crawler.

The Fusion system combined with Intelligent Torque output and closed-loop speed control means the power system will maintain the motor’s Torque level and RPM as the vehicle conditions change. Uphill, downhill, under load, the intelligent output torque makes the operation so simple. Note?If the“RPM/Throttle Matching” be set to “Disabled”, no intelligent torque output & speed closed-loop control, just like the brushed system.

The Fusion Pro system adopts FOC driving mode; low-speed torque is strong. It runs smoothly at very low speed, outstripping ordinary sensored power system, even better than a brushed power system. Moreover, the motor is extremely silent when it is running. The driving noise which annoys the driver disappears. It is the best choice for a rock crawler.

The IP-67 waterproof of the whole power has an excellent waterproof and dustproof performance. The whole power can easily drive on the muddy, sandy, icy, snowy, and water track under various weather conditions.

The whole power adopts FOC driving which has high efficiency and less heat, dramatically extending the runtime. Benefiting from the sine wave driving mode, the motor runs more silently and softly.

8 gears of drag brake force and 9 gears of drag brake rate can meet different car models, different fields, and different controlling habits. The maximum drag brake force is about twice that of ordinary brushless power of the same size, providing super strong parking capacity on a slope.

Compare to standard on/off switches, the dust, dirt, and waterproof electronic switch housing ensures a long reliable life for your power system, will not suffer from the problems that reed stuck, and contact rust frequently happened in a dusty and damp environment and the problem that mechanical switch closes automatically caused by a fierce impact.

• The integrated design of the ESC and the motor greatly reduces the overall volume and weight and makes the layout and wiring of the car frame simpler and more convenient. 
• In the FOC driving mode, low-speed torque is strong. Smooth running at extremely low speed, which is far superior to the common sensored brushless power system, even better than the brushed power.
• Thanks to the sine wave driving mode, the whole system has high efficiency, small heat, and effectively extends the endurance time; and the motor runs more quietly and soft.
• The protection grade of the whole system is IP67, with excellent waterproof and dustproof performance. Under various weather conditions, the whole system can easily deal with the complex road surface containing silt, ice and snow, and water.
• Intelligent torque output and speed closed-loop control, fully experience the cruise control and steep slope slow descent function of 1:1 vehicle, making the control handy.
• Active drag brake force adjustment, providing unprecedented parking capacity on a slope.
• With a strong built-in switch mode BEC, the continuous current is up to 6A, and support switch between 6V and 7.4v, easy to drive various powerful steering servos and high-voltage steering servo. • Multiple protection functions: battery low voltage protection, overheat protection, throttle lost protection, lock-up protection.
• Supports HOBBYWING LED program box to set ESC parameters and has an independent parameter setting interface, which is integrated with an electronic switch, making setting parameters more convenient.
