TomCat Skyclaw 20A ESC 3-4S Lipo for Multi-Rotor

The TomCat Skyclaw 20A ESC is equipped with advanced programming features that allow you to tweak the performance to your liking. You can adjust the throttle response, motor timing, and other parameters to perfectly balance speed and control. It's designed to handle up to 20 amps of power. 3-4s Li-po. Burst current (10s): 30A


Adopt high-frequency MCU (up to 50MHz) as the main control chip, the computing speed of the ESC is faster, and the response speed of the throttle is dramatically improved.

Applying the synchronous rectifier technology can increase the ESC efficiency (significantly reduce the ESC temperature), improve the throttle linearity, and speed up the deceleration response of the motor.

The ESCs only have one programmable item (Timing). It is very simple to use.

The ESCs are compatible with PPM signal-receiving mode (the throttle signals range from 1100μs to 1940μs) and OneShot125 signal-receiving mode (the throttle signals range from 125μs to 250μs).

In PPM signal-receiving mode, the frequency of the throttle signal supported by the ESCs is up to 500Hz and compatible with various flight controllers.

The twisted-pair design of the throttle signal cable effectively reduces the crosstalk produced in signal transmission and makes the flight more stable.

The ESCs have high efficiency and strong reliability by using specialized power tubes to drive the chip.

Start-up protection: If the motor fails to start within 2 seconds while pushing the throttle stick upward, the ESC will cut off the output power. You need to put the throttle stick to the lowest position again and then restart the motor. It happens in the following situations: poor connection or disconnection between the ESC, motor, and propellers are blocked, Etc.

Throttle signal loss protection: If the throttle signal is lost for over 0.25 seconds, the ESC will cut off the output immediately to avoid greater losses caused by the high-speed rotation of the propeller. The ESC will recover the output immediately after normal signals are received.

Programmable Item

Users can set the program items only on PPM signal-receiving mode. The Skyclaw series ESCs only have one programmable item (Timing). Values of Timing: High and Middle. The default is middle.
