1. Увод
The Eachine E120S is a super classic helicopter designed for excellent flight performance. Its flybarless design reduces rotor head resistance, and its aerodynamic blades provide strong power and stability. Utilizing the latest gyro technology, this helicopter supports both 3D and 6G modes. The 3D mode allows for a variety of stunts, while the 6G mode is ideal for beginners due to its stability.
This micro-helicopter is noted for its compact size and optimized structure, which enhances flight stability and reduces the likelihood of damage. Once properly set up, beginners will find it easy to fly and quickly master new maneuvers. The built-in 'rescue' or upright function in 6G mode can often save the helicopter in challenging situations.
This manual provides detailed instructions to help you understand and operate your E120S helicopter effectively, saving time and avoiding issues from incorrect settings.

5. Подешавање
Пуњење батерије:
Да бисте осигурали сигурност, користите приложени стандардни пуњач.

- Connect the charger USB plug into a USB power adapter or a computer USB port. If no battery is connected, the USB charger's red light will flash.
- Once the battery is plugged into the USB charger, the charger's red light will illuminate, indicating charging is in progress.
- When the battery is fully charged, the USB red light will turn off.
Напомена: Када је батерија волtage is lower than 7.4V, the lithium battery may be damaged and may no longer charge correctly. If the battery voltage drops below 7.4V during flight, the main ESC will significantly reduce head speed. Land immediately and charge the battery as soon as possible.
Binding with Transmitter:
If you have the RTF package, your helicopter is already paired at the factory. If you need to re-pair, follow these steps:

- First, turn on the transmitter. Ensure the throttle stick is at the bottom position and the 3D IDLE switch is in the OFF position.
- Remove the canopy to access the binding switch.
- Apply power to the helicopter. The red LED will flash slowly. Press the code button for 1 second. The red lamp will then turn off, indicating it's ready for pairing.
- When both the red and blue lights on the helicopter turn solid, the pairing is successful.
- While pairing, ensure no other transmitters are operating nearby to avoid unintended pairing.
Савет: This product is compatible with all FUTABA 2.4GHZ S-FHSS transmitters.
6. Операција
Pre-Flight Notice:
- Ensure the batteries for both the transmitter and helicopter are fully charged.
- Before turning on the transmitter, ensure the throttle control is at the lowest position and the TH.HOLD and 3D mode switches are in the back position (towards the back cover).
- Make sure the transmitter has paired with the helicopter. If not, perform the pairing process.
- Turn on the transmitter first, then connect the battery to the helicopter and wait until it pairs with the transmitter. When turning off, unplug the power from the helicopter first, and then turn off the transmitter.
