- Attach the signal cable to your receiver and perform calibration.
- Test motor direction and throttle response.
Can it be used with a 3S Li-Po battery?
Yes, it works perfectly with 3S (11.1V) Li-Po batteries. Ensure voltage does not exceed 12.6V.
What is the purpose of the BEC output?
The BEC (Battery Eliminator Circuit) supplies 5V/2A power to components like the receiver and servos.
What happens in case of overheating?
The ESC automatically shuts down when the temperature exceeds 110°C to protect components.
How do I calibrate the motor?
Move the throttle stick to maximum, power the ESC, wait for two beeps, then move the stick to minimum.
Any installation tips?
Mount the ESC in a ventilated area for better heat dissipation and use double-sided tape to reduce vibration.
