Fearless Challenge Fixed-wing ESC,support 6S battery 2 2oF Bec2A@BV Receere 0 Lipo 2-38 .

This series ESC features a dedicated fixed-wing core algorithm, optimized for high-performance motor control. The software structure has been carefully designed to ensure exceptional proficiency in controlling motors. With original imported components and an ingenious PCB layout, this ESC offers high-quality, stable, and cost-effective performance.

The AT series speed controller features a built-in BEC (Battery Eliminator Circuit) that provides a stable and high-efficiency output, ensuring safe operation in various power supply environments.

Featuring hardware filtering and synchronous continuous current function, this speed controller provides fast and reliable throttle control. Additionally, it boasts multiple protection functions, including abnormal voltage detection, thermal shutdown, low battery voltage warning, and loss-of-throttle signal alerts.

Features Multiple Programmable Parameters: This ESC offers wide-ranging parameter settings that allow it to easily accommodate various application scenarios across different environments. Additionally, it supports LED programming cards, simplifying the setup process.

**Important Disclaimer**: This AT (Fixed Series) ESC manual is intended for use under normal power systems only. Any misuse or incorrect operation may pose a risk to RC models. Please note that all devices are original and manufactured with high-quality components, ensuring the ESC’s reliability and performance.

(2) When setting the type for NiMH batteries, the low, medium, and high cutoff voltages are set as a percentage of the startup voltage. A value of 0% disables the low cut-off function.

The AT series speed controller supports two to three servos (servo-motors) and requires calibration of the throttle range before flight. To calibrate, emit a ‘beep’ tone from the transmitter, connect it to the ESC, and wait for 2 seconds.

If the motor fails to start within 2 seconds, the ESC (Electronic Speed Controller) will automatically shut down its power output. If the throttle signal is lost for 1 second, and no further input is received within the subsequent 2-second period, the ESC will completely cut off its output.

After powering on, the motor fails to operate and an alert tone is emitted. The throttle direction (‘56712’ channel) has been inadvertently reversed, causing the SET (special tone) to sound after two brief beeps.

The T-MOTOR AT 20A ESC will initially beep

To adjust settings, navigate to ‘Select Parameter Items’ and choose from six available options. The motor will produce a series of beeps when you make a selection. Once you’ve reached the desired parameter value, the motor will emit a distinct beep sequence (‘i515’) to indicate that the changes have been saved.

The ESC emits a beep to alert you to the number of LiPo cells connected. If you’re using multiple batteries, you’ll need to reinsert them or adjust your configuration accordingly. Additionally, ensure that the power supply is turned off when the battery levels are low.
