4. Operating Instructions
4.1 Remote Controller Overview
Familiarize yourself with the remote controller's layout and functions.
Figure 4: The remote controller allows selection of 3 different speed modes.
- Left Joystick (Throttle): Controls altitude (up/down).
- Right Joystick (Directional): Controls forward/backward, left/right movement.
- One-Key Take-off/Landing Button: Initiates automatic take-off or landing.
- Speed Mode Button: Cycles through 3 speed levels (low, medium, high).
- Trim Buttons: Used to correct unwanted drifting (e.g., if the helicopter drifts left, press the right trim button).
4.2 Take-off and Landing
- One-Key Take-off: After pairing, press the One-Key Take-off/Landing button. The helicopter will automatically ascend and hover at a stable altitude.
- Manual Take-off: Slowly push the left joystick (throttle) upwards to make the helicopter ascend.
- One-Key Landing: During flight, press the One-Key Take-off/Landing button. The helicopter will automatically descend and land gently.
- Manual Landing: Slowly pull the left joystick (throttle) downwards to make the helicopter descend. Once on the ground, hold the joystick down for a few seconds until the rotors stop.
Figure 5: The helicopter features Altitude Hold and One-Key Take-off/Landing for ease of use.
4.3 Altitude Hold Function
The DE28S is equipped with an automatic altitude hold function. After take-off, release the throttle joystick, and the helicopter will maintain its current altitude, making it easier to control for beginners.
4.4 Drifting Movement
Unlike many other RC helicopters, the DE28S can perform side-to-side drifting movements in addition to standard forward, backward, and rotational movements. Use the right joystick to control these directional movements.
Figure 6: The DE28S helicopter is capable of unique side-to-side drifting movements.
4.5 Speed Modes
The helicopter offers 3 speed modes to suit different skill levels and flying environments. Press the speed mode button on the remote to switch between low, medium, and high speeds. Low speed is recommended for beginners and indoor flying, while high speed is suitable for experienced pilots and outdoor conditions.
5. Maintenance
5.1 Cleaning
To maintain optimal performance, regularly clean your helicopter. Use a soft, dry cloth to wipe down the body and blades. Avoid using water or chemical cleaners, as they can damage electronic components.
5.2 Blade Inspection and Replacement
Periodically inspect the main and tail rotor blades for any signs of damage, cracks, or deformation. Damaged blades can affect flight stability and safety. If a blade is damaged, replace it with a genuine DEERC spare part. Refer to the package contents for included spare blades or contact DEERC support for replacements.
Figure 7: The DE28S features durable and flexible blades.
5.3 Storage
When not in use, store the helicopter and remote controller in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries from the remote controller if storing for extended periods to prevent leakage.
6. Troubleshooting
If you encounter issues with your DEERC DE28S helicopter, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Helicopter does not respond to remote. | Not paired, low battery in remote or helicopter, out of range. | Re-pair the helicopter and remote. Charge helicopter battery. Replace remote batteries. Ensure helicopter is within 2.4 GHz range. |
| Helicopter cannot take off or flies weakly. | Low helicopter battery, damaged blades, motor issue. | Fully charge the helicopter battery. Inspect and replace damaged blades. If motor issue persists, contact support. |
| Helicopter drifts during flight. | Needs trimming, uneven surface for take-off. | Use the trim buttons on the remote to correct drift. Always take off from a flat, level surface. |
| LED lights not working. | Power issue, damaged LED. | Ensure helicopter is powered on and battery is charged. Contact support if lights remain non-functional. |
