Instruction Manual

1. Introduction

This manual provides comprehensive instructions for the safe and effective use of your FLYCOLOR 90A Waterproof Brushless Electronic Speed Controller (ESC). Designed for model ships and RC boats, this ESC features a powerful MCU, smooth throttle linearity, and multiple protection functions. Please read this manual thoroughly before operation to ensure optimal performance and longevity of your device.

2. Safety Information

• Always disconnect the battery from the ESC when not in use to prevent accidental motor activation.
• Ensure all connections are secure and properly insulated to avoid short circuits.
• Operate the ESC within its specified voltage and current limits.
• Keep the ESC away from extreme temperatures and direct sunlight.
• This product is recommended for users aged 14 years and up. Adult supervision is advised for younger users.
• In case of overheating (above 100°C), the ESC will automatically reduce output power. Allow it to cool down before resuming full operation.

3. Product Features

• Powerful and high-performance MCU for intelligent control.
• User-configurable functions to meet specific demands.
• Unique circuit design with strong anti-interference capabilities.
• Adjustable start mode for fast throttle response and smooth speed control linearity.
• Compatible with various scale boats and racing boats.
• Adjustable low-voltage protection threshold.
• Built-in switch BEC (5.5V/5A) for large power load with servo, ensuring lower power dissipation.
• Waterproof design for reliable operation in marine environments.
• Multiple protection functions: input voltage abnormal protection, low-voltage cutoff protection, over-thermal protection, and throttle signal loss protection.
• High power safety performance: motor will not start immediately regardless of throttle lever position.
• Cycle menu setting for simple operation.
• Supports setting with a program box and transmitter.

5. Setup and Installation

Proper installation is crucial for the performance and safety of your ESC. Follow these steps carefully:

1. Mounting: Securely mount the ESC in a well-ventilated area within your model ship or RC boat. Ensure it is protected from physical impact.
2. Motor Connection: Connect the three motor phase wires from the ESC to your brushless motor. The order of connection may affect motor rotation direction. If the motor spins in the wrong direction, swap any two of the three motor wires.
3. Battery Connection: Connect the XT90 battery connector of the ESC to your compatible LiPo battery (2-6S). Ensure correct polarity: red to positive (+), black to negative (-).
4. Receiver Connection: Plug the small signal cable from the ESC into the throttle channel of your RC receiver (usually channel 2).
5. Water Cooling (if applicable): If your model utilizes a water cooling system, ensure the water inlet and outlet tubes are properly connected to the ESC's cooling ports.

6. Operating Instructions and Programming

The ESC offers various programmable settings to optimize performance. These settings can typically be adjusted using your transmitter or a dedicated program card.

6.1 Initial Calibration (Throttle Range)

1. Turn on your transmitter and set the throttle trim to neutral.
2. Connect the battery to the ESC while holding the throttle stick at full throttle.
3. Wait for the ESC to emit a series of beeps indicating it has detected the full throttle position.
4. Move the throttle stick to the lowest position (full brake/reverse).
5. Wait for another series of beeps indicating the lowest throttle position has been set.
6. The ESC is now calibrated and ready for use.

6.2 Programmable Parameters

The FlyMonster-90A ESC allows users to set various functions. Refer to the program card manual (if using one) for detailed instructions on each parameter. Common adjustable parameters include:

• Running Mode: Forward/Brake, Forward/Brake/Reverse.
• Motor Direction: Normal/Reverse.
• Low Voltage Cutoff: Adjustable threshold to protect battery.
• Start Mode: Punch level for initial acceleration.
• Timing: Motor timing adjustment for efficiency or power.
• BEC Voltage: Fixed at 5.5V.

7. Maintenance and Care

• After each use, especially in saltwater, rinse the ESC with fresh water to remove any salt or debris.
• Ensure the ESC is completely dry before storage.
• Regularly inspect all wires and connectors for signs of wear, damage, or corrosion. Replace damaged components immediately.
• Store the ESC in a cool, dry place away from direct sunlight and extreme temperatures.
• Do not attempt to open or modify the ESC casing, as this may void the warranty and compromise its waterproof integrity.
