USER MANUAL

Dear customers: 

Thank   you   for   using   the   smart   power   electric   speed   controller   (ESC)   for   brushless   motor   designed   and 
produced by HobbyKing.com. Wrong use and operation may cause personal injuries  and damages  on the 
equipment due to the strong power at the starting of the product. We strongly recommend customers to read the 
specification   carefully   before   using   the   product   and   operate   the   product   strictly   in   accordance   with   the 
operating provisions. We assume no responsibilities generated from the application of the product, including 
but not limited to liabilities for damage of incidental losses or indirect losses. Meanwhile, we assume no 
responsibilities   generated   from   the   disassembly   and   modification   by   users   themselves   and   assume   no 
responsibilities caused by products from the third party. 
We have the right to alter products including appearance, performance parameter and operating requirement 
without advanced notice. We make no guarantee, declaration or promise on whether the product is suitable for 
specific purpose of users. 

I. The main properties of electric speed controller for brushless motor

 

Use powerful and high-performance MCU processor. The users can set function of use according to their 

requirements. It fully reflects the smart property of our products as a unique advantage. 
●  Support unlimited rotate speed of brushless motor
●  Support the function of fixed speed
●  Delicate circuit design with strong anti-interference

 

The starting mode can be set. The response speed of throttle is very quickly and with very stable linear of 

speed regulation. It can be used in fixed wing aircraft and helicopter
●  Threshold values of low-voltage protection can be set.

 

With internal SBEC, the operating power to start steering engine is strong and the power dissipation is 

small.
●  Multi protection function: protection for abnormal input voltage/ protection for low battery/ protection for 

overheat/protection of lowing power when lost of signals from throttle

 

Good safety performance under energization: the motor will not start at the time of power on regardless of 

the location of pull rod of throttle in controller.

 

Protection for overheat: the output power will lesson to half when the temperature reaches 100  during the

 

operation of ESC. The output power will automatic recover when the temperature is under 100

 

Supports with operation setting for all controller and setting of programming panels 

●  Set alarm sound. And judge the working situation after power on.
●  The company has completed intellectual property on the product. The product can be continuingly updated 
and upgraded. The product can be made to customers’ requirements.
