These parts are designed to replace original components and restore optimal performance to your helicopter. Please read this manual carefully before attempting any installation or repair.
2. Product Overview
The ESKY BIG LAMA RC Helicopter spare parts are individual components available for replacement. The range of parts includes:
- Controller (3-in-1)
- Propeller Blades (various sets)
- Main Shaft (Axis)
- Stabilizing Hammer
- Fixed Rod
- Main Frame
- Motor (Type B)
- Landing Gear
Ensure you have identified the correct part for replacement before proceeding.
3. Setup and Installation
Installation of spare parts requires careful attention to detail. Always refer to your original ESKY BIG LAMA helicopter's main instruction manual for specific disassembly and reassembly steps. The following are general guidelines for common parts:
3.1 Controller (3-in-1)
Image: ESKY001337 3-in-1 Controller. This unit integrates the receiver, ESC, and gyro functions.
Carefully disconnect all wires from the old controller. Note the orientation and connection points for each wire (motors, servos, battery). Install the new controller in the same position and reconnect all wires securely. Ensure no wires are pinched or stressed. Test functionality before flight.
3.2 Motor (Type B)
Image: ESKY000838 Motor B. This motor is a replacement for the main rotor drive.
Remove the old motor from its mounting bracket. Disconnect its wires from the controller. Install the new motor, ensuring proper alignment with the gear system. Connect the motor wires to the controller, observing correct polarity if applicable. Verify smooth rotation of the gears and rotor system.
3.3 Propeller Blades

Replace damaged blades by carefully removing the retaining screws or pins. Ensure the new blades are installed with the correct orientation (top/bottom rotor) and securely fastened. Improper installation can lead to instability or loss of control.
3.4 Main Shaft (Axis)

The main shaft is central to the helicopter's rotor system. Replacement typically involves disassembling the rotor head and main gear assembly. Ensure all bearings and collars are correctly positioned and secured during reassembly.
3.5 Stabilizing Hammer and Fixed Rod

These parts are critical for the helicopter's stability and control. Replace bent or broken components carefully, ensuring all linkages move freely without excessive play. Proper balance of the stabilizing hammer is essential.
3.6 Main Frame and Landing Gear

If replacing the main frame, transfer all components (motors, controller, battery tray, servos) from the old frame to the new one. Ensure all screws are tightened appropriately. Landing gear typically attaches to the bottom of the frame with screws or clips; ensure it is firmly attached to absorb impact.
4. Operating Considerations
After replacing any spare part, it is crucial to perform a thorough pre-flight check:
- Visual Inspection: Check all connections, screws, and moving parts for security and proper alignment.
- Functionality Test: Power on the helicopter and transmitter. Test all control surfaces (throttle, elevator, aileron, rudder) to ensure they respond correctly and smoothly.
- Rotor Balance: For propeller blades, ensure they are balanced to prevent vibrations during flight.
- Initial Hover: Perform a gentle hover test in a safe, open area to observe flight characteristics and stability.
Always operate your RC helicopter in accordance with the original manufacturer's safety guidelines and local regulations.
5. Maintenance
Regular maintenance of your ESKY BIG LAMA RC Helicopter parts will extend their lifespan and ensure safe operation:
- Cleaning: Keep all parts free from dirt, dust, and debris. Use a soft brush or cloth.
- Inspection: Regularly inspect propeller blades for cracks or chips, the main shaft for bends, and the frame for stress fractures.
- Lubrication: Apply a small amount of appropriate lubricant to moving parts like gears and bearings as recommended by the original helicopter manual.
- Fasteners: Periodically check all screws and fasteners for tightness. Vibrations can cause them to loosen over time.
6. Troubleshooting
If you encounter issues after replacing a part, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Helicopter unstable/vibrates | Damaged or unbalanced propeller blades, bent main shaft, loose stabilizing hammer/fixed rod. | Replace damaged blades, check main shaft for straightness, ensure stabilizing hammer and fixed rod are secure and balanced. |
| Motor not spinning or weak | Loose motor wires, faulty motor, issue with controller. | Check motor connections, ensure battery is charged, test with a known good motor if possible. |
| Loss of control/unresponsive | Faulty controller, incorrect wiring, damaged servo linkages. | Verify all controller connections, ensure transmitter is bound, check servo movement. |
| Helicopter won't lift off | Incorrect propeller blade orientation, weak motor, low battery. | Ensure blades are installed correctly (leading edge up), check motor power, fully charge battery. |
