MT120A- HV -OPTO (6s-12s) is a 120A brushless speed controller that can handle a maximum current burst of 150A.

Its performance in terms of compatibility, reliability and stability can compete with world famous brands.

Features:

• Support High RPM motors.
• Circle menu setting is simple.
• Power arming protection:
• Prevents the motor from accidentally running when switched ON
• Lost Throttle signal protection:
• The ESC will automatically reduces output power to the motor when it detects a lost of throttle signal for 1 second. A subsequent loss of throttle signal beyond 3 seconds will cause the ESC automatically to cut power to the motor.
• Safety thermal over-load protection:
• Automatically reduce output power to half when the temperature reaches 110℃, restore output power when the temperature is below 110℃.
• Can continuously provide power to the motor.
• Acceleration: Provides quick acceleration start ups with a linear throttle response.
• Governor Mode: For Helicopter application
• With latest humanize software design, especially for all types of brushless motor.
• New advanced programming software.
