Introducing the Hobbywingn QuicRun Fusion 8IGHT Climbing integrated power system.
Integrated design
The industry's first commercialized FOC integrated power system suitable for 1/ 8th scale models has an overall size of only 42*69mm , making the frame layout and wiring simpler and more beautiful , effectively solving the problem of difficult wiring in climbing vehicles due to small internal space.
4S High Power Climbing ESC
The ESC supports up to 4S LiPo.
Maximum continuous output 80A.
In addition, the small size design can not only be used for 1/ 8th climbing models, but also meet the needs of 1/ 7th light-load climbing models.
Adjust the drag brake force in real time
When the yellow signal line is connected to an idle channel of the receiver, the remote controller can be used to adjust the braking force in real time, easily meeting the braking force requirements in various application environments.
FOC drive, good linearity, high torque, and almost silent.
Adopting FOC drive mode, the torque is very strong when running at low speed, and it runs very smoothly even at extremely low speed, which is far superior to ordinary sensory power systems and even better than brushless power.
In addition, the driving noise that drivers hate is solved when the motor is running, and it is almost silent.
Intelligent torque output, easy to control.
When the car is going uphill, the ESC automatically increases the output torque to overcome the resistance and go uphill smoothly;
When going downhill, the electronic control automatically reduces the output torque and stabilizes the vehicle speed.
The intelligent output torque can effectively control the speed and make the vehicle easy to control.
Note: When the operation mode is set to normal mode, there is no fixed speed function, which is similar to the effect of brushless operation.
All-weather and all-terrain operation capability
The entire power system has an IP67 protection grade and excellent waterproof and dustproof performance. It can easily cope with complex roads containing mud, snow, ice and water .
Note: The IP67 protection level mentioned above is splash-proof, water-resistant and dust-proof under normal use, but it is not permanent and the protection performance may decrease due to daily wear and aging. Do not soak in water for a long time, otherwise it may damage the product.
Powerful built-in BEC
Built-in powerful BEC with maximum output current of 13A
Output voltage can be switched between 6V/7.4V/8.4V
It can easily drive various standard servos, high-voltage servos and peripheral electrical equipment (such as lights, winches, etc.) .
