✨ Core Features

1. ✅ Power‑on safety function: Motor will not start immediately after power‑on regardless of throttle stick position, effectively avoid accidental injury.
2. ✅ Throttle travel calibration: Compatible with different remote controller throttle travel, deliver linear throttle response for smooth speed adjustment.
3. ✅ Rich programmable items:

• Brake setting: No brake / With brake, factory default: No brake
• Battery type: Li‑xx Lithium battery / Ni‑xx Nickel battery, factory default: Li‑xx
• Low‑voltage protection mode: Reduce power / Cut off output, factory default: Reduce power
• Low‑voltage threshold: Low / Medium / High; For Li‑xx:2.6V / 2.85V /3.1V per cell. For Ni‑xx: 0% /45% /60% of input voltage.
• Starting mode: Normal / Soft / Ultra‑soft start. Normal for fixed‑wing; Soft & Ultra‑soft for helicopter.
• Advance timing: Low / Medium / High, factory default: Medium advance timing.
• Support restore factory default setting.

🛡️ Multiple Protection Functions

• Under‑voltage protection: Configurable via program settings
• Over‑voltage protection: Alarm beep and refuse startup when input voltage over 18V
• Over‑temperature protection: Auto shut‑down when MOSFET temperature exceeds safe value
• Signal loss protection: Reduce power after 1s signal loss, cut output after extra 2s

🔧 Process Characteristics

1. Large‑capacity high‑impedance electrolytic capacitor on power input for anti‑interference performance.
2. Independent heat sink for MOSFET power tubes to lower temperature rise for high‑current operation.
3. MCU independent voltage regulator chip, avoid BEC load disturbance and guarantee stable operation.
4. Signal wire definition: Red‑positive, Black‑negative, Yellow‑signal.

📝 Setup & Calibration Guide

1. Turn on transmitter, push throttle stick to maximum position (FUTABA series need reverse throttle channel).
2. Correctly connect ESC with motor and receiver.
3. Power on ESC. Follow buzzer beep prompts to complete battery mode, brake and other parameter configuration.
4. Brushless ESC three motor wires can connect randomly; swap any two wires if motor rotates reverse.
5. First‑time use must finish throttle range calibration to recognize transmitter max/min throttle travel.

⚠ Important Usage Notice

Kind reminder: If there are version differences or images not been updated, please refer to the actual product.

• Do not exceed the rated current and voltage range.
• Check wiring status before power‑on to prevent short‑circuit damage.
• Ground test motor performance before formal flight.
