ZTW Spider PRO 30A 390 ESC (2-6 Cells) ZTW5030302

The ZTW Spider PRO Premium 30A 390 (2-6 Cells), part number ZTW5030302, is a 30A electronic speed controller (ESC) from ZTW for use with 2 to 6 cells. It uses a new generation of MOSFETs, which the manufacturer says keeps heat build-up low and improves reliability.

The manufacturer lists extremely low internal resistance and smooth, accurate throttle linearity, and the controller supports high RPM motors. Protection features include thermal overload protection, automatic throttle shut-down if the signal is lost, and power arming protection, which stops the motor from running accidentally when the controller is switched on.

The ESC weighs 20 g (0.71 oz) and has an age recommendation of 14+. As with any speed controller, it needs to be matched to the motor, battery and model it will be used with, so check suggested compatibility against your own setup before installing it.
