- Outdoor Use: These airplanes are designed for outdoor use in wide, open spaces, free from obstacles, people, or animals.
- Supervision: Adult supervision is recommended, especially during initial assembly and operation.
- Impact Hazard: While durable, avoid stepping on the airplanes or subjecting them to excessive force to prevent damage.
3. Package Contents
The Quercetti Sirius & Libella package includes components for assembling two airplanes. Verify that all parts are present before beginning assembly.
- 2 Reinforced Wings (one for Sirius, one for Libella)
- 2 Fuselages (one for Sirius, one for Libella)
- 1 Propeller (for Libella)
- Nose cones/Tips
- Ballasts/Weights
- Decorative Stickers
- Assembly Accessories (e.g., elastic band for Libella)
4. Setup and Assembly
Assembly of both the Sirius glider and Libella elastic-powered airplane is straightforward and can be completed in a few minutes. Detailed assembly instructions and example albums are available on the official Quercetti website. To access these, visit the Quercetti website and enter code 3585 in the search menu located at the top right.
- Identify Components: Separate the parts for the Sirius glider and the Libella elastic-powered plane.
- Assemble Fuselage and Wings: Attach the wings to the respective fuselages. Ensure they are securely fitted.
- Attach Tail Sections: Secure the tail fins to the rear of each fuselage.
- Install Propeller (Libella only): For the Libella model, attach the propeller to the front of the fuselage and connect the elastic band mechanism.
- Apply Stickers: Personalize your airplanes with the provided decorative stickers.
- Adjust Ballast: Insert the provided ballasts or weights into the designated areas to achieve proper balance. This is crucial for stable flight.

5. Operating Instructions
Both airplanes are designed for outdoor use. Choose a large, open area free from trees, buildings, or other obstructions that could interfere with flight or cause damage.
5.1. Sirius Glider Operation
- Launch: Hold the glider firmly by the fuselage and launch it with a gentle, upward throw into the wind.
- Trimming for Flight:
- Adjusting Ballast: Experiment with the ballast placement to find the optimal center of gravity for stable, long flights.
- Wing Adjustment: A slight adjustment (minimal displacement) of the main wing to the right or left can induce a gentle turn in that direction during flight.
- Wind Conditions: The glider performs best in light breezes. Strong winds may make control difficult.
5.2. Libella Elastic-Powered Airplane Operation
- Winding the Elastic Motor:
- Hold the airplane securely.
- Rotate the propeller clockwise to wind the elastic band.
- Do not exceed 100 turns to prevent over-stressing the elastic and potential damage.
- Launch: Once wound, hold the airplane by the fuselage and release it with a forward motion. The propeller will engage, propelling the plane.
- Trimming for Flight: Similar to the Sirius, adjust the internal counterweight (ballast) for optimal balance and flight path. Minor wing adjustments can also influence turning.
- Flight Characteristics: The Libella is designed for powered flight, followed by a glide as the elastic unwinds.
6. Maintenance
Proper care will extend the lifespan of your Quercetti airplanes.
- Handling: These airplanes are lightweight and delicate. Handle them with care during assembly, launch, and retrieval.
- Landing Surfaces: Aim for soft landing surfaces like grass to minimize impact damage. Hard surfaces can cause wear and tear on the wings and fuselage.
- Storage: Store the airplanes in a safe place where they will not be stepped on or crushed.
- Elastic Band (Libella): The elastic band may lose elasticity over time with frequent use. Replacement elastic bands can be sourced if needed.
- Stickers: If decorative stickers detach, they can be re-applied with a suitable adhesive.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Airplane flies poorly or crashes quickly. | Incorrect balance (ballast), improper launch, or strong wind conditions. | Adjust the internal ballast to find the optimal center of gravity. Launch gently into a light breeze. Ensure wings are straight and not bent. |
| Libella (elastic-powered) does not fly far or has weak propulsion. | Insufficient winding of the elastic motor or worn-out elastic band. | Ensure the propeller is wound clockwise for up to 100 turns. If the elastic is old, consider replacing it. |
| Airplane consistently turns sharply or veers off course. | Wing or tail fin misalignment. | Check that the wings and tail fins are straight and securely attached. Make minor adjustments to the main wing for controlled turns. |
| Airplane lands on obstacles (e.g., roofs). | Launching in an area with insufficient clear space. | Always operate the airplanes in wide, open outdoor areas, away from buildings, trees, and other obstructions. |
