3.2 Nabíjení baterie
The quadcopter uses a 25C 3S 2200mAh 11.1v LiPO battery. Use the provided GA-005 balance charger.
- Connect the GA-005 charger to a 110-240V AC power source or a 5V DC source.
- Connect the LiPO battery to the balance charger. Ensure correct polarity.
- Sledujte proces nabíjení. Po plném nabití baterii odpojte, abyste zabránili jejímu přebití.
- Always charge batteries on a fire-resistant surface and never leave charging batteries unattended.
3.3 Transmitter (Devo7) Preparation
The Walkera Devo7 transmitter requires 8 Lithium Ion batteries (included). Install them according to the polarity markings in the battery compartment.
3.4 Kalibrace
Before the first flight and periodically thereafter, perform the following calibrations:
- Kalibrace kompasu: Follow the instructions in the quick start guide to calibrate the compass. This is crucial for accurate GPS functions.
- Gyro and Accelerometer Calibration: Ensure the quadcopter is on a level surface during this calibration to maintain stable flight.
4. Návod k obsluze
4.1 Základní ovládací prvky letu
Familiarize yourself with the Devo7 transmitter controls. Practice slowly in a safe, open environment until you are comfortable with the quadcopter's response.
4.2 Pokročilé funkce
- GPS Altitude Hold System: This feature allows the quadcopter to maintain a stable altitude and position using GPS signals.
- One Key Return Home: Activates an automatic return-to-home function, guiding the quadcopter back to its takeoff point. Ensure GPS signal is strong before using.
- Altitude Sensor: Assists in maintaining a consistent flight height.
- FPV Capability: The quadcopter supports First Person View (FPV) systems for real-time video transmission (additional equipment may be required).
- Ovládání Wi-Fi: Optional Wi-Fi control allows for operation via a mobile device (additional modules may be required).
