ZTW Gecko Series 2-6S SBEC 125A Electric Speed Controller

If you want the best, the very best ESC for your demanding applications then look no further than the ZTW 'Gecko' series. Supeb build quality with finned andodised aluminium body with lightweight end caps, and legendery ZTW bullet proof reliability makes the 'Gecko' series the ESC of choice for those that want the very best.

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.

The Switch-Mode BEC has been specifically 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 and complicated fixed wing models.

This ESC features a huge 8A SBEC output with adjustable voltage of either 5.0v, 6.0v, 7.4v or 8.4v - at last an ESC than can handle high voltage servos without the need for a seperate regulator!
