Example Models
Some of the exciting models you can construct include:
- Motorized Crane: A functional crane with a rotary body and extendable hook.
- Helicopter: A detailed model with rotating blades.
- Buggy Crane: A mobile crane for various tasks.
- Broadcasting Vehicle: A specialized vehicle for communication.



Operating Your Models
Once your model is fully assembled and the motor is connected, you can bring your creation to life. The motor provides functional motion to your models. Refer to the specific model instructions for details on how to activate and control its movements.
Maintenance
- Keep all parts clean and dry. Wipe down metal parts with a dry cloth if they become dusty.
- Store all components in the provided carrying case to prevent loss and damage. The case features compartments for organized storage.
- Regularly check nuts and bolts for tightness, especially after extended play, and re-tighten as necessary.
- Remove batteries from the motor unit if the set will not be used for an extended period to prevent battery leakage.
Troubleshooting
Motor Not Functioning
- Ensure batteries are correctly installed and are not depleted. Replace with fresh batteries if needed.
- Verify all electrical connections between the battery case and the motor are secure.
- Check the motor's switch: Ensure it is fully engaged in the ON position (either forward or reverse). If the switch is left in an intermediate position, it may cause overheating and damage to the motor unit. Always ensure the switch is fully thrown to one side or completely in the center OFF position.
- Inspect gears for any obstructions or misalignment that might prevent movement.
