ZTW manufactures high-performance brushless electronic speed controllers (ESCs) and motors for RC cars, boats, airplanes, and drones.
Shenzhen ZTW Model Science & Technology Co., Ltd is a prominent manufacturer in the radio control (RC) hobby industry, specializing in the development and production of brushless electronic speed controllers (ESCs) and motors. Established with a focus on quality and performance, ZTW provides power systems for a wide range of RC applications, including 1/10 and 1/8 scale cars, racing boats, fixed-wing aircraft, and multi-rotor drones.
The brand is well-known for its popular product lines such as the Beast, Mantis, Shark, and Beatles series, which cater to both amateur hobbyists and professional racers. ZTW products are characterized by their reliability, smooth throttle linearity, and advanced programmable features, often supported by LED program cards or mobile apps.

To calibrate the throttle, connect the ESC to the receiver and battery, turn on your transmitter, and hold the power button (or follow your specific model's sequence) until the LED serves as a prompt. Move the throttle trigger to full throttle, then full brake/reverse, and finally neutral, waiting for the confirmation beeps at each step.
Bi-Direction capability allows the motor to rotate in both forward and reverse directions. This feature is essential for RC cars and boats that need to back up, whereas aircraft ESCs typically only rotate in one direction.
Overheating can be caused by poor airflow, using a propeller that is too large, incorrect gear ratios, or exceeding the voltage limits. Ensure your setup matches the ESC's specifications and that the cooling heat sink is not obstructed.
Most ZTW ESCs can be programmed using the transmitter stick inputs or a separate LED Program Card. Some advanced models, like the Beast Pro G2, support Bluetooth programming via a mobile app.
The initial beeps usually indicate the detected battery cell count (e.g., 3 beeps for a 3S LiPo). If the beeps continue indefinitely or follow a specific pattern, it may indicate a throttle signal loss or that the throttle is not in the neutral position.
