Wishiot 1.5g Micro Digital Analog Linear Servo Instruction Manual

1. Introduction

The Wishiot 1.5g Micro Digital Analog Linear Servo (Model FH-1502) is a lightweight and high-performance linear actuator designed for ultra-micro 3D flight aircraft and other weight-sensitive remote control projects. This servo supports both digital and analog control signals, offering versatility and precise control. Its compact size and efficient design make it an ideal choice for applications where space and weight are critical factors.

2. Product Features

• Dual Control Compatibility: Supports both digital and analog control signals for broad compatibility.
• Lightweight Design: Optimized for 1-cell powered applications where minimal weight is crucial.
• High Performance: Features a high-torque motor combined with fast response for precise movements.
• Ideal for Ultra-Micro 3D Flight: Specifically designed to meet the demands of ultra-micro 3D aircraft and indoor flyers.
• Durable Construction: Equipped with a standard nylon gear type and standard wiring for reliable operation.

3. Specifications

Note: Due to manufacturing variations, the appearance of the servo may differ slightly between new and old production batches. Both types are functionally identical and shipped randomly.

2. Wiring Connection: Connect the servo to your receiver or flight controller according to the following color code:
   • Red Wire: Positive power supply (+)
   • Black Wire: Negative power supply (-) / Ground
   • White Wire: Signal input
   Ensure correct polarity to prevent damage to the servo or your control system.

3. Power Supply: The servo operates within a voltage range of 3.7V to 5V. Ensure your power source (typically a 1-cell LiPo battery or BEC) provides stable voltage within this range.
4. Control System Integration: Connect the signal wire to the appropriate channel on your receiver or flight controller. Configure your radio transmitter or flight controller software to send the correct digital or analog servo signals.

5. Operating Instructions

Once properly installed and connected, the Wishiot 1.5g Micro Linear Servo will respond to control signals from your radio system. The servo's linear actuator will move back and forth, providing precise control for surfaces such as ailerons, elevators, or rudders in ultra-micro aircraft.

• Initial Test: Before flight or full operation, perform a range test to ensure the servo moves smoothly and covers the required travel distance without binding.
• Centering: Most control systems allow for servo centering adjustments. Ensure the servo is centered correctly for neutral control surface positions.
• Travel Adjustment: Adjust the servo travel limits on your transmitter or flight controller to prevent over-driving the servo, which can lead to damage or reduced lifespan.

6. Maintenance

The Wishiot 1.5g Micro Linear Servo is designed for durability, but proper maintenance can extend its lifespan and ensure consistent performance.

• Keep Clean: Regularly inspect the servo for dirt, dust, or debris that could impede its movement. Use a soft brush or compressed air to gently clean the mechanism.
• Avoid Obstructions: Ensure that the linear actuator's path is free from any obstructions during operation. Binding can cause excessive strain on the motor and gears.
• Check Connections: Periodically check all wiring connections for looseness or damage. Secure connections are vital for reliable operation.
• Storage: When not in use, store the servo in a clean, dry environment away from extreme temperatures and direct sunlight.

7. Troubleshooting

If you encounter issues with your Wishiot 1.5g Micro Linear Servo, refer to the following troubleshooting steps:

• Servo Not Responding:
  • Check power connections (Red and Black wires) to ensure they are secure and correctly polarized.
  • Verify the power supply voltage is within the 3.7V-5V operating range.
  • Confirm the signal wire (White) is correctly connected to the receiver/flight controller and that the control signal is being sent.
  • Test with a different servo channel or a known working servo to isolate the problem.
• Erratic or Jerky Movement:
  • Inspect for any physical obstructions preventing smooth linear movement.
  • Check for loose wiring connections, especially the signal wire.
  • Ensure the power supply is stable and not experiencing voltage drops.
  • Verify that the control signal is clean and free from interference.
• Servo Binding or Stalling:
  • Ensure the servo is not mechanically overloaded or trying to move beyond its physical limits. Adjust linkages or control surface throws if necessary.
  • Check for foreign objects or debris in the linear mechanism.
