What's in the box
1x FOC motor w/ built-in ESC
Factory installed XT60 plug
1x Decal and Manual
1x Heatsink kit, double-sided tape, and zip ties.

Bottomline
Integrated design of Hobbywing's patent technology
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.

Intelligent Torque Output & Speed Closed-loop Control for Easy Control
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

FOC (Field-oriented Control) for Super Linearity & HighTorque & Extreme Mute
The Fusion 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.

Waterproof: Applicable to All Weather & Track Conditions
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.

High Driving Efficiency for Long Battery Life
The whole power adopts FOC driving which has high efficiency and less heat, dramatically extends the Runtime time. Benefitting from the sine wave driving mode, the motor runs more silently and softly.

Professional Drag Brake Adjustments & Super Parking Capacity
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.

Advanced and Secure Electronic Switch
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 happed in dusty
and damp environment and the problem that mechanical switch closes
automatically caused by a fierce impact.
