Feature: 1. [Adjustable Throttle Response] The startup mode can be set, which is used to adjust the throttle response time of ESC acceleration from 0 to 100 percent. 2. [High Safety] Including abnormal start guard, overheat guard, throttle signal loss guard, low voltage cutoff guard, etc. The motor will not start immediately regardless of throttle position. 3. [Easy to Operate] The RC brushless ESC supports various programming methods, including remote control, programming, making it easy to operate at home or during flying. 4. [2-3S LiPo Input] The RC electric speed controller supports 2-3S LiPo batteries input, 5V 2A BEC output (linear mode), with a peak current of 40A. 5. [Multi Purpose] This RC brushless ESC is suitable for modeling enthusiasts and RC hobbyists, replacing damaged parts or upgrading your model airplane. Specification: Item Type: RC Brushless ESC Material: ABS Input: 2-3S LiPo Peak Current: 40A BEC Output: 5V 2A (Linear Mode) Features: 1. Braking Force When you move the throttle stick to the bottom position, the brake function will be activated. In this mode, the braking force equals to your preset braking force. 2. Voltage Cut off Types 2.1 Soft Cut off Selecting this option, the ESC will gradually reduce the output to 60% of full power within 3 seconds after the low voltage cut off guard is activated. 2.2 Hard Cut off Selecting this option, the ESC will immediately cut off the output when the low voltage cut off guard is activated. 3. LiPo Battery If Auto Calculate is chosen, the ESC will automatically calculate the quantity of the LiPo battery inserted based on the 3.7V/Cell rule, or you can manually set this option. Note: 15A, 20A can only choose the following parameters: Auto Calculate, 2S, 3S. 4. Cut off Voltage If triggered, the low voltage guard function will be disabled. In addition, the guard voltage values of the low/medium/high modes correspond to approximately 2.8V/cell, 3.0V/cell, 3.4V/cell. This value is the voltage of a single cell multiplied by the number of li batteries automatically identified by the ESC or manually set, that is, the guard voltage of the battery. (For example, if the low voltage guard threshold for a 3 cell lithium cell is medium, the guard voltage of the battery is 3x3.0=9.0V) 5. Start up Mode This is used to adjust the throttle response time of ESC acceleration from 0 to 100 percent. Normal/soft/very soft correspond to approximately 200ms/500ms/800ms respectively. 6. Time schedule The timing value of the drive motor can be adjusted. Low/medium/high are 5°/15°/25° respectively. 7. Active Sliding (DEO) This option can be adjusted between Enabled and Disabled, and is enabled by default. After activation, you can achieve better throttle linearity or smoother throttle response. 8. Search Mode After selecting this option, when the throttle is held at 0% for the set time, ESC will drive the motor to beep and prompt. . Package List: 1 x ESC 1 x Accessory 2 x Protective Covers 1 x Instruction Manual Note: The default throttle range for this ESC is 1100µs to 2000µs (double leaf standard); throttle range calibration is required when users start using a new brushless ESC or other transmitters.
