Integy WP-S16-RTR 25A Waterproof Brushless Electronic Speed Controller Instruction Manual

1. Introduction

This manual provides essential information for the proper installation, operation, and maintenance of your Integy WP-S16-RTR 25A Waterproof Brushless Electronic Speed Controller (ESC). Designed for 1/16 and 1/18 scale RC cars, this ESC offers reliable performance with 2S or 3S LiPo battery compatibility. Please read this manual thoroughly before use to ensure safe and optimal performance.

2. Safety Instructions

Adherence to the following safety guidelines is crucial for preventing damage to the ESC, other components, and personal injury.

Battery Safety: Always use batteries within the specified voltage range (2-3S LiPo or 6-9 cells NiMH). Incorrect voltage can cause severe damage.
Polarity: Ensure correct battery polarity when connecting. Reverse polarity will damage the ESC.
Waterproof Rating: While this ESC is waterproof, it is not designed for prolonged submersion. Always dry the ESC thoroughly after exposure to moisture to prevent corrosion.
Motor Compatibility: Use only with compatible brushless motors as specified in the 'Specifications' section.
Ventilation: Ensure adequate airflow around the ESC during operation to prevent overheating.
Disconnection: Always disconnect the battery from the ESC when not in use to prevent accidental activation and battery discharge.
Children: This product is not a toy. Keep out of reach of children under 15 years of age. Adult supervision is recommended during operation.

Key components include:

ESC Unit: The main control module.
Motor Wires: Three wires (typically blue, yellow, orange) for connecting to a brushless motor.
Battery Wires: Red (+) and Black (-) wires for connecting to the battery.
Receiver Wire (Rx Wire): Connects to the throttle channel of your RC receiver.
Power Switch: Integrated switch for turning the ESC on and off.
Built-in BEC: Provides regulated 6V/1A power to the receiver and servos.

4. Setup and Installation

Follow these steps for proper installation of the ESC into your RC vehicle.

Mounting the ESC: Securely mount the ESC in your vehicle using double-sided tape or zip ties, ensuring it is protected from excessive vibration and impact. Allow for adequate ventilation.
Motor Connection: Connect the three motor wires from the ESC to the corresponding wires on 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.
Receiver Connection: Plug the receiver wire (Rx Wire) from the ESC into the throttle channel (usually channel 2) of your RC receiver.
Battery Connection: Connect your battery pack to the battery wires of the ESC, ensuring correct polarity (red to positive, black to negative).
Initial Calibration (Throttle Range):
- Turn on your transmitter and ensure the throttle trim is at neutral.
- With the ESC power switch off, connect the battery.
- Press and hold the ESC's power button (if applicable, or follow specific calibration instructions for your model if different).
- Turn on the ESC. Release the button when the LED flashes.
- Move the throttle stick to full throttle and hold. The ESC will beep.
- Move the throttle stick to full brake/reverse and hold. The ESC will beep again.
- Return the throttle stick to neutral. The ESC will beep, indicating calibration is complete.

5. Operating Instructions

Once installed and calibrated, your ESC is ready for operation.

Power On: Turn on your RC transmitter first, then turn on the ESC using its power switch.
Driving: Operate your vehicle using the transmitter's throttle and steering controls.
Power Off: Always turn off the ESC first, then turn off your transmitter. Disconnect the battery immediately after use.
Overheat Protection: The ESC features built-in overheat protection. If the ESC becomes too hot, it may reduce power or shut down temporarily. Allow it to cool before resuming operation.
Low Voltage Cutoff (LVC): For LiPo batteries, the ESC has an LVC feature to prevent over-discharge. When the battery voltage drops below a safe level, the ESC will reduce power or cut off to protect the battery.

6. Maintenance

Regular maintenance ensures the longevity and performance of your ESC.

Cleaning: After each use, especially in dusty or wet conditions, clean the ESC. Use a soft brush or compressed air to remove dirt and debris. For wet conditions, ensure the ESC is completely dry before storage or next use.
Inspection: Periodically inspect all wires and connectors for signs of wear, fraying, or corrosion. Replace damaged components immediately.
Storage: Store the ESC in a cool, dry place away from direct sunlight and extreme temperatures. Always disconnect the battery before storage.

7. Troubleshooting

Refer to this section for common issues and their potential solutions.

Problem	Possible Cause	Solution
Motor does not run or runs intermittently.	Battery not connected or low voltage. Loose motor or receiver connections. Incorrect throttle calibration. Motor or ESC damage.	Check battery connection and charge level. Verify all connections are secure. Perform throttle calibration (Section 4). Inspect motor and ESC for visible damage.
Motor runs in the wrong direction.	Incorrect motor wire connection order.	Swap any two of the three motor wires between the ESC and motor.
ESC overheats.	Insufficient ventilation. Motor gearing too high. Motor limit exceeded.	Ensure proper airflow around the ESC. Reduce motor pinion size or increase spur gear size. Verify motor compatibility with ESC specifications.
Vehicle stops or loses power suddenly.	Low Voltage Cutoff (LVC) activated. Overheat protection activated.	Recharge or replace battery. Allow ESC to cool down.
