ZTW GECKO SERIES Airplane/Heli ESCs are competition-grade speed controllers from one of the most trusted RC electronics manufacturers in the industry. NEW FEATURES found in Gecko Series ESCs include PC data logging, firmware upgradability, and an 8A SBEC adjustable up to 8.4v to help your HV servos reach their fullest potential! Best of all, Gecko Series ESCs come standard with the ZTW quality, performance, and reliability you have come to trust.
The high power SBEC found in ZTW Gecko Series ESCs has been specifically designed for extreme aerobatics and therefore has the capability to support the higher momentary peak demand loads 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.
