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