3. Setup

3.1. Battery Installation and Charging

Aircraft Battery: Locate the battery compartment on the underside of the aircraft. Connect the rechargeable lithium battery to the aircraft's power connector. Ensure a secure connection. To charge the aircraft battery, use the provided USB charging cable. Connect the battery to the charging cable, and then plug the USB end into a compatible USB power source (e.g., computer, USB wall adapter). The charging indicator will show the charging status (refer to charger for specific light indications). Disconnect once fully charged.

Remote Control Batteries: The remote control requires 2 AA batteries (not included). Open the battery compartment on the back of the remote control and insert the batteries, observing the correct polarity (+/-). Close the compartment securely.

3.2. Assembly

The GoolRC FX635 is designed for quick assembly. Attach the landing gear to the designated slots on the underside of the fuselage. Ensure they are firmly in place. The propellers are pre-installed; however, if replacement is needed, carefully attach new propellers to the motor shafts, ensuring correct orientation.

4. Operating Instructions

4.1. Pairing the Remote Control

1. Ensure the aircraft battery is connected and the aircraft is powered on.
2. Turn on the remote control by pressing the power button. The indicator light on the remote will flash.
3. Move the throttle stick (left stick) all the way up, then all the way down. The remote control will beep, and the indicator light will become solid, indicating successful pairing.

4.2. Flight Controls

The FX635 features a two-channel control system:

• Left Stick (Throttle): Controls ascent and descent. Push up to increase power and climb, pull down to decrease power and descend.
• Right Stick (Direction): Controls left and right turns. Move left to turn left, move right to turn right.

The built-in 3-axis gyroscope assists in stabilizing the aircraft, making it easier to maintain level flight, especially for beginners.

4.3. Take-off and Landing

Take-off: Place the aircraft on a flat, open surface. Slowly increase the throttle. As the aircraft gains speed, it will lift off. Alternatively, you can hand-launch the aircraft by gently throwing it forward while simultaneously increasing throttle.

Landing: Gradually reduce the throttle to decrease altitude. Guide the aircraft towards a clear landing area. For a smooth landing, maintain a slight forward momentum until the landing gear touches down, then fully reduce throttle.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your GoolRC FX635 RC Airplane.

• Cleaning: After each flight, gently wipe down the aircraft with a soft, dry cloth to remove any dirt or debris. Avoid using harsh chemicals.
• Propeller Inspection: Regularly check the propellers for any damage (cracks, bends). Damaged propellers can affect flight performance and stability. Replace them with spare parts as needed.
• Battery Care: Store batteries in a cool, dry place. Do not overcharge or over-discharge the battery. If the aircraft will not be used for an extended period, charge the battery to approximately 50% before storage.
• Material Care: The EPP foam material is durable but can be damaged by strong impacts. Inspect the fuselage for any tears or dents. Minor damage can often be repaired with appropriate foam-safe adhesive.
