This ZTW 20A Programmable Brushless ESC is perfect for mid-size scale, sport or 3D airplanes. This ESC's internal BEC and low-voltage cutoff settings make it ideal for use with 2S (7.4V), 3S (11.1V), or 4S (14.8V) Li-Po batteries. Better yet, the ZTW 20A will auto-detect the number of lipo cells in your battery and set the appropriate cut-off voltage without any programming required.
All ZTW A-Series ESCs provide a variety enhanced performance and safety features, including super-smooth and accurate throttle linearity, extremely low internal resistance, auto throttle shutdown if signal is lost, thermal overload protection, and more. For users whose projects demand versatility, this ESC offers a variety of advanced programming options:
