2. Product Features

• Brushless ESC: Output Continuous Current 80A; Instantaneous Current 100A; Input: 2-6S LiPo.
• BEC: 5V@5A (Built-in Switch Mode BEC Regulators).
• Throttle Range Calibration: Function to adapt to throttle differences between various transmitters, improving throttle response linearity.
• Comprehensive Protection Features: Includes undervoltage protection, overvoltage protection, overheat protection, and remote signal loss protection.
• Security Power Function: Prevents immediate motor startup upon power-on, regardless of throttle stick position, to enhance safety.

4. Safety Precautions

• Always connect the battery last and disconnect it first.
• Ensure all connections are secure and properly insulated to prevent short circuits.
• Keep hands and loose clothing away from propellers when the ESC is powered on.
• Never operate the ESC in wet conditions.
• Verify correct motor rotation before flight.
• Use only compatible batteries (2-6S LiPo) and motors.

5. Setup & Installation

5.1 Wiring Connections

1. Connect the three black wires from the ESC to your brushless motor's three wires. The order may affect motor rotation, which can be adjusted later.
2. Connect the signal cable (usually a three-wire servo connector: white/yellow for signal, red for positive, black/brown for negative) from the ESC to the throttle channel of your RC receiver.
3. Connect the red and black power input wires of the ESC to your LiPo battery. Ensure correct polarity (red to positive, black to negative).

5.2 Throttle Range Calibration

To ensure optimal performance, calibrate the ESC's throttle range with your transmitter. This synchronizes the ESC with your transmitter's throttle stick positions.

1. Turn on your transmitter and set the throttle stick to its maximum (highest) position.
2. Connect the battery to the ESC. The motor will emit a series of beeps.
3. When you hear two short beeps, quickly move the throttle stick to its minimum (lowest) position.
4. The motor will emit a long beep, indicating successful throttle range calibration.
5. Disconnect the battery to save the settings.

6. Operating Instructions

After successful setup and calibration, your ESC is ready for operation. Always perform a pre-flight check to ensure all components are functioning correctly.

• Power On: Connect the battery. The ESC will initialize with a series of beeps.
• Arming: Ensure the throttle stick is at the lowest position. The ESC will arm, indicated by a specific tone, and the motor will be ready to spin.
• Throttle Control: Slowly increase the throttle stick to control motor speed.
• Power Off: Always lower the throttle to minimum, then disconnect the battery first.

7. Programming the ESC

The Readytosky 80A ESC offers programmable parameters to customize its behavior. Programming can typically be done via your transmitter or a dedicated programming card (if available and compatible).

7.1 Programming via Transmitter

This method uses specific throttle stick movements and audible beeps to navigate and select programming options.

1. Turn on your transmitter and move the throttle stick to the top (maximum) position.
2. Connect the battery to the ESC. After a few seconds, you will hear a special tone indicating entry into programming mode.
3. The ESC will then emit a sequence of beeps, each corresponding to a programmable item (e.g., 1 beep for SMR Function, 2 beeps for Brake Type, etc.).
4. To select an item, move the throttle stick to the bottom (minimum) position immediately after hearing the corresponding number of beeps.
5. The ESC will then emit a new sequence of beeps, indicating the values for that item. Move the throttle stick to the top position after hearing the beep sequence for your desired value.
6. The ESC will confirm the setting with a long beep and return to the main programming menu. Repeat steps 3-5 for other items.
7. To exit programming mode, disconnect the battery.

7.2 Setting SMR (Switch Motor Rotation) Function

The SMR function allows you to reverse motor rotation, which is useful for specific aircraft configurations or landing assistance. This function is typically activated via a 2-stage switch on your transmitter.

• Ensure the SMR function is enabled in the ESC programming (refer to the programming instructions above).
• Assign a 2-stage switch on your transmitter to control the SMR function.
• When the aircraft is landing on the ground, flipping this switch can effectively shorten the landing distance by reversing motor thrust.
• Note: The SMR function is effective only when the throttle is below 50%.

8. Troubleshooting

• Motor not spinning: Check all wiring connections, ensure the battery is charged, and verify throttle calibration.
• Motor stutters or runs irregularly: Re-check motor wire connections, ensure proper motor timing settings, and verify battery voltage.
• ESC overheats: Ensure adequate airflow around the ESC, check for motor overload, or consider a higher-rated ESC if consistently overheating.
• No response from ESC: Confirm receiver is powered and bound to the transmitter, check signal wire connection, and ensure ESC is armed.
