Compatibility
This motor set is specifically designed for use with the following RC helicopter models:
- SYMA S022 RC Helicopter
- SYMA S34 RC Helicopter
Using these motors with incompatible models may result in damage to the helicopter or the motors themselves.
Safety Precautions
- Always disconnect the helicopter's battery before performing any maintenance or installation.
- Handle small components with care to avoid loss or damage.
- Keep motors and small parts away from children.
- Ensure proper ventilation when working with electronic components.
- If unsure about any step, consult a qualified technician or the manufacturer's support.
Installation Instructions
Follow these steps carefully to replace the main motors in your SYMA S022 or S34 RC Helicopter. A small Phillips head screwdriver may be required.
- Disconnect Power: Ensure the helicopter's battery is disconnected and removed to prevent accidental activation.
- Identify Motors: Locate the existing front and rear main motors on your helicopter. Note their orientation and wiring. The front motor (S022-19) typically has a different wire color combination or connector position than the rear motor (S022-20).
- Remove Rotor Blades: Carefully remove the main rotor blades from the motor shafts. This provides better access and prevents injury.
- Disconnect Wiring: Gently unplug the wiring harness of the old motors from the helicopter's main circuit board. Take care not to pull on the wires directly.
- Remove Old Motors: Unscrew any retaining screws or release clips holding the old motors in place. Carefully extract the old motors from their mounts.
- Install New Motors: Insert the new front motor (S022-19) into the front motor mount and the new rear motor (S022-20) into the rear motor mount. Ensure they are seated correctly and secure them with any screws or clips removed earlier.
- Connect Wiring: Connect the wiring harnesses of the new motors to the corresponding ports on the main circuit board. Ensure the front motor's wires connect to the front motor port and the rear motor's wires connect to the rear motor port. Incorrect connection can cause improper operation or damage.
- Reattach Rotor Blades: Carefully reattach the main rotor blades to the motor shafts, ensuring they are securely fastened.
- Final Check: Visually inspect all connections and ensure no wires are pinched or loose.

Operating Instructions (Post-Installation)
After successful installation:
- Reconnect Battery: Reinsert and connect the helicopter's battery.
- Power On: Turn on the helicopter and its remote control.
- Initial Test: Perform a low-power test flight in a safe, open area. Observe the helicopter's stability and responsiveness. Ensure both motors are spinning correctly and providing adequate lift.
- Adjustments: If the helicopter exhibits unusual behavior, refer to the troubleshooting section or the helicopter's main instruction manual for trim adjustments.
Maintenance
Regular maintenance helps extend the lifespan of your motors:
- Cleanliness: Keep the motors free from dust, dirt, and debris. Use a soft brush or compressed air for cleaning.
- Wire Inspection: Periodically check motor wires and connectors for any signs of wear, fraying, or damage. Replace if necessary.
- Avoid Overheating: Allow motors to cool down between flights, especially after intensive use, to prevent overheating.
- Gentle Operation: Avoid sudden, aggressive maneuvers that can put excessive strain on the motors.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not spin. | Loose or incorrect wiring connection. Damaged motor. | Check all motor connections to the circuit board. Ensure correct front/rear motor placement. If connections are secure, the motor may be faulty and require replacement. |
| Helicopter flies erratically or spins. | Incorrect motor orientation (front motor in rear position, or vice versa). Damaged rotor blades. | Verify that the front motor (S022-19) is in the front position and the rear motor (S022-20) is in the rear position. Check rotor blades for damage and replace if necessary. |
| Reduced flight time or power. | Weak battery. Motor wear. | Ensure the helicopter battery is fully charged. If the issue persists, motors may be nearing the end of their lifespan and require replacement. |
