Lista kontrolna przed lotem
- Ensure both aircraft and remote control batteries are fully charged.
- Confirm all parts (landing gear, tail wing, propellers) are securely attached.
- Check that control surfaces (ailerons, elevator) respond correctly to remote control inputs.
- Select an open, clear outdoor area free from obstacles, people, and animals.
- Check wind conditions; avoid flying in strong winds.
Instrukcja obsługi

The 6-axis gyro stabilization system provides enhanced stability, making the aircraft easy to control even for beginners.
Take-Off Methods

Image: The DEERC BF-109 RC Plane illustrating two take-off methods: hand-thrown and ground take-off using the included landing gear.
- Hand-Thrown Take-Off: Hold the aircraft firmly, engage the throttle to full power, and gently toss it forward into the wind. The gyro will assist in stabilizing the flight.
- Ground Take-Off: Place the aircraft on a smooth, flat surface. Engage the throttle gradually and steer with the rudder until it gains enough speed to lift off.
Podstawowe sterowanie
- Przepustnica (lewy drążek w górę/w dół): Increases or decreases engine power.
- Ster kierunku (lewy drążek w lewo/prawo): Controls yaw (left/right turning).
- Winda (prawy drążek w górę/w dół): Steruje kątem nachylenia (nos w górę/w dół podczas wznoszenia/opadania).
- Ailerons (Right Stick Left/Right): Controls roll (tilting wings left/right for banking turns).
Zaawansowane manewry
With practice, the 3-channel control system allows for various maneuvers:
- Pętle: Gain altitude, then apply full elevator (right stick down) while maintaining sufficient throttle.
- Banking Turns: Use ailerons (right stick left/right) to roll the aircraft, then apply a small amount of elevator to maintain altitude through the turn.
