ZTW Gecko 120A High Voltage Aircraft ESC

This is a high voltage version Gecko ESC supports up to 12S LiPo, but no built in BEC.

GECKO series also include ESC OPTO for giant flying. This series of ESCs also features an exposed, finned heat sink aluminum case with lightweight plastic end caps. Additional features include safe power arming along with advanced programmable, data logging system, low voltage cutoff, braking, timing, throttle input range, and more, making this series truly a pro series speed control.

As the development of the electronic and popular demand and designed for extreme aerobatics and therefore has the capability to support the higher current applications to eliminate the possibility of unwanted shutdowns, and is also capable of supporting continuous simultaneous multiple servo operations typically found in CCPM equipped hardcore 3D E-helicopters.

Data logging system such as temperature, voltage, current, RPM,
