Setup Guide
1. Charge the Flight Battery
The E-flite 500mAh 1S 3.7V 25C Li-Po flight battery must be fully charged before first use. Connect the included USB LiPo Battery Charger to a compatible USB power source. Connect the flight battery to the charger. The charger's indicator light will show charging status (refer to charger instructions for specific light patterns). Disconnect the battery once charging is complete.
2. Install Transmitter Batteries
Open the battery compartment on the back of the multi-function transmitter. Insert the four included AA batteries, ensuring correct polarity. Close the battery compartment securely.
3. Pre-Flight Check
- Ensure all blades and components are securely attached and free from damage.
- Verify the flight battery is fully charged and securely installed in the helicopter.
- Confirm the transmitter batteries are installed and the transmitter is powered on.
- Perform a range check in an open area before the first flight.
Operating Instructions
Binding the Helicopter and Transmitter
Before first flight, or if you are using a new transmitter, you will need to bind the helicopter to the transmitter. Refer to the specific binding instructions in the included 120 S2 RTF Manual for detailed steps. Generally, this involves powering on the transmitter, then the helicopter, and initiating a binding sequence.
Flight Environment
The Blade 120 S2 is suitable for both indoor and outdoor flight. For outdoor flight, choose an area with low wind conditions. Ensure the flight area is clear of obstacles, people, and animals.
Basic Flight Controls
- Throttle (Left Stick Up/Down): Controls the main rotor speed for ascent and descent.
- Rudder (Left Stick Left/Right): Controls the tail rotor for yaw (rotating the helicopter left or right).
- Aileron (Right Stick Left/Right): Controls side-to-side movement (roll).
- Elevator (Right Stick Up/Down): Controls forward and backward movement (pitch).
SAFE® Technology and Panic Recovery
The Blade 120 S2 features exclusive SAFE® (Sensor Assisted Flight Envelope) Technology, which provides self-leveling and flight envelope protection, making it easier to learn and fly. In case of disorientation or loss of control, press the Panic Recovery button on your transmitter (refer to transmitter manual for button location). This will instantly return the helicopter to a stable, level attitude. Figure 2: The Blade 120 S2 helicopter demonstrating stable flight characteristics during indoor operation.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Blade 120 S2 helicopter. Its durable construction helps withstand minor impacts, but periodic checks are still recommended.
- After Each Flight:
- Inspect main and tail rotor blades for cracks, chips, or bends. Replace damaged blades immediately.
- Check landing gear for any damage or looseness.
- Ensure all screws and fasteners are tight.
- Wipe down the helicopter to remove any dust or debris.
- Periodically:
- Check motor connections and wiring for wear or damage.
- Inspect the main shaft and linkages for smooth movement and no excessive play.
- Ensure the flight battery is not swollen or damaged. Store LiPo batteries safely.
Troubleshooting Guide
| Problem | Possible Cause | Solution |
|---|---|---|
| Helicopter does not respond to transmitter. | Not bound, low transmitter battery, low flight battery. | Ensure binding procedure is followed. Replace transmitter batteries. Charge flight battery. |
| Helicopter drifts or is unstable. | Trim settings incorrect, damaged blades, environmental factors (wind). | Adjust trim on transmitter. Inspect and replace damaged blades. Fly in calmer conditions. |
| Short flight time. | Battery not fully charged, old battery, over-discharged battery. | Ensure battery is fully charged. Consider replacing old batteries. Avoid over-discharging. |
| Tail rotor not working correctly. | Damaged tail rotor blade, motor issue, loose connection. | Inspect and replace tail rotor blade. Check tail motor connections. |
