FAQs
Can it be used with a 3S Li-Po battery?
Yes, it works efficiently with 3S lithium polymer batteries (11.1 volts). Make sure the voltage does not exceed 12.6 volts.
What is the purpose of the BEC outputs?
The Battery Elimination Circuit (BEC) provides 5 volts/2 amps power for components such as the receiver and servomotors.
What happens in case of high temperature?
The ESC automatically shuts off when the temperature exceeds 110 degrees Celsius to protect the components.
How do I calibrate the motor?
Move the throttle stick to the maximum, then turn on the electronic controller steady, wait to hear two sounds, then move the stick to the minimum.
Any installation tips?
Install the Electronic Speed Controller in a well-ventilated area for better heat dissipation and use double-sided tape to reduce vibration.
