Návod k obsluze
Basic Controls (MODE1/MODE2)
The DE28S supports Controller Modes 1 and 2. Refer to your remote controller's specific layout for exact joystick functions.
- Levý joystick (plyn): Ovládá nadmořskou výšku (nahoru/dolů).
- Pravý joystick: Controls forward/backward movement and left/right turning (yaw).
- Ořezávací tlačítka: Used to correct unwanted drifting.
One-Key Take-off and Landing
After pairing, press the One-Key Take-off button (usually marked with an arrow pointing up from a line) on the remote controller. The helicopter will automatically ascend to a stable altitude. Press the One-Key Landing button (usually marked with an arrow pointing down to a line) to initiate an automatic landing.

The DE28S features Altitude Hold and One Key Take-off/Landing for easy operation.
Režim držení nadmořské výšky
The helicopter is equipped with automatic altitude stabilization. Once airborne, it will maintain its current height, allowing you to focus on directional control.
Trimming for Stable Flight
If the helicopter drifts in any direction without input, use the trimming buttons on the remote controller to adjust its balance. For example, if it drifts left, press the right trim button until it hovers steadily.
Drifting Movement (Sideways Flight)
Unlike traditional helicopters, the DE28S can perform side-to-side drifting movements. Use the appropriate joystick input (refer to your remote's specific controls) to move the helicopter sideways left or right.

The DE28S offers unique side-to-side drifting movement.
Režimy rychlosti
The helicopter features 3 speed modes. Press the speed button on the remote controller to cycle through low, medium, and high speeds. Start with low speed for beginners and indoor flight, then progress as you gain experience.

| Problém | Možná příčina | Řešení |
|---|---|---|
| Vrtulník nereaguje na dálkové ovládání. | Not paired, low battery in helicopter or remote, out of range. | Re-pair the helicopter and remote. Charge/replace batteries. Ensure within 40m range. |
| Vrtulník se během letu unáší. | Needs trimming adjustment, uneven surface during takeoff. | Use trimming buttons to correct drift. Ensure takeoff from a flat surface. |
| Krátká doba letu. | Baterie není plně nabitá, stará baterie, agresivní létání. | Ensure batteries are fully charged. Consider replacing old batteries. Fly more gently. |
| Vrtulník snadno havaruje. | Lack of experience, flying in confined spaces, strong winds. | Practice in open areas. Start with low speed. Avoid windy conditions. |
