ZTW hardware + SimonK firmware = a match made in multi-rotor heaven!
ZTW Spider Series ESCs are high quality speed controllers designed for simple installation and easy setup in your multi-rotor aircraft. Flashed with the latest version of the popular SimonK firmware, Spider Series ESCs can support super fast refresh rates up to 600Hz for an incredibly smooth yet crisp flight controller response. They also feature a smooth and linear throttle range without sacrificing a rapid, crisp response to throttle input. As usual. Spider Series ESCs come standard with the ZTW quality, performance, and reliability you have come to trust.
