THIS PRODUCT IS RECOMMENDED FOR OPERATORS OVER 14 YEARS OLD. THE RC GLIDER IS DIFFICULT TO LEARN AT THE EARLY STAGE. OPERATORS CAN FLY ONLY AFTER SKILLFULLY OPERATING THE MODEL GLIDER ON THE SIMULATOR.

Installation procedure

Horizontal tail and vertical tail

• A. Insert the locating pin below the vertical tail into the locating hole of the horizontal tail.
• B. Insert the horizontal tail and vertical tail into the locating hole of the fuselage.
• C. Flip the fuselage over, lock the vertical tail in place with screws, and connect the fuselage wire fittings to the horizontal tail and the vertical tail.
• D. Insert the tail landing gear back in until the wire snaps into the slot.

Installation of wings

• A. Turn the fuselage upside down to expose the circuit board inside, and insert the two connecting wires of the wing servo into their female sockets, respectively.
• B. Insert the front bulge of the wing into the fuselage recess, straighten out the wires and lines, and gently press the back half of the wing until it fits tightly.
• C. Lock the wing to the fuselage with the screws.

Installation of landing gear
Snap the landing gears on the left and right sides of the wing into the grooves underneath the wing and press down until the wire snaps into the slot.

Note: Tilt slightly forward to install the landing gear.

Installation of gun (optional)
Align the missile protrusion with the groove below the wing and press it in.

Installation of propeller
Unscrew the nut on the brush-less motor, install the propeller, and tighten the nut again.

The aircraft is fully assembled.

Usage of the charger

1. Insert the battery into the USB charging port and plug the USB into the charging socket.
   Then the red light is on and the green light flashes slowly.

2. When the battery is fully charged, the red light is off and the green light is on.

Warnings:

1. Charge under supervision for safety.
2. Children should not charge alone unless assisted by an adult.
3. Do not charge with a charger other than the original one to prevent an expiosion or fire.

Flight preparation

• Open the RC, check, and confirm the throttle lever is in the bottom position and the other levers are in the middle position.
• Open the battery cover and connect the battery connector to the interface inside the battery cover as shown in Figure B.
• After connecting the battery, put the battery into the battery slot and cover the battery as shown in Figure C. After the gyroscope finishes the self-test, you can operate to fly.

Flight pre-adjustment

1. Open the RC and lay the aircraft on flat and clean ground. Connect the power battery and then cover it. Before running the motors (the gyroscope is not working at this time), check whether the control surfaces are in the center position and the direction of deflection is correct, then check whether the motor is running steadily or not.
2. The wire can be shortened by rotating it to the right and lengthened by rotating it to the left.
3. Check whether the center of gravity of the aircraft is within a proper range:The center of gravity of the aircraft should be within 25mm-35mm from the front edge of the wing.

Frequency pairing

1. Open the canopy and connect the battery with the receiver. If the method is correct, a prompt tone will sound.
2. Lay the aircraft flat, and press the RC switch button. (The RC ticks once), the red light is on, and the blue light flashes.
3. Push the throttle to maximum and pull it back to minimum. (At this time, the RC ticks twice), the blue light remains on, and the frequency pairing is completed. Then, install the aircraft battery cover back.
   Note: When in frequency pairing, no working RC of the same type and frequency is allowed in the surroundings; otherwise, it may cause pairing failure.

MM/3D/6G conversion

1. The three positions on the right side of the RC are the changeover switches for flight attitudes.
2. One tick indicates MM mode. In this mode, the gyroscope does not operate in the flight, so it is only recommended for professional flight training.
3. Two ticks indicate 6G mode. This mode is recommended for beginners, and the gyroscope will augment artificial stability and make flying easier. In this mode, the aircraft can only fly level and cannot do any aerobatic maneuver, including horizontal roll, inverted flight, sideward flight, half-loop roll, etc.
4. Three ticks indicate the 3D mode. This mode is assisted by the gyroscope, and basic maneuvers can be performed in this mode. Press the corresponding button on the RC to perform a maneuver as follows: Upper left A: left horizontal roll; upper right B: right horizontal roll; Lower left C: half-loop roll with one button; and Lower right D: level flight with one button.

Note: A: The gyroscope will be activated after the brush-less motor turns on.
B: an aerobatic show with one button can be performed only when the aircraft reaches a certain altitude.

BEGINNERS SOUND OPERATE IN 6G MODE TO MINIMIZE THE RISK OF CRASHING.

Ground takeoff

1. Place the aircraft on the ground facing the wind and check again whether each control surface is centered and in the correct direction.
2. After confirmation of the above steps, gently push the throttle lever and gently pull the elevator lever until the aircraft is off the around.

Takeoff by throw
Throw the aircraft vigorously at an angle of 5° against the wind, with the motor on full power, as shown in the figure below.
(Note: When the aircraft takes off in 6G mode, it will fly in ascending attitude for about 5 seconds and then level off automatically if it is thrown correctly. As the aircraft has an attitude correction function, it is recommended not to pull down the elevator lever at this stage if the aircraft does not tend to lower its nose, otherwise, the aircraft will tend to lower in the opposite direction.)

Function

landing

When the aircraft is flying, if the RC alarms (red light flashing) and the aircraft appears to be under-powered, land it immediately. First, operate the aircraft to fly to the downwind area, then adjust the nose to face the wind.
Pull the throttle down to lower the flight speed. The aircraft will slowly glide down until it touches the ground. Then pull the throttle down to the lowest level. Adjust the flight attitude to keep it steady during the glide.

End of flight
Remove the batteries from the aircraft at the end of the flight.
Do form good habits to prevent any danger.

Warnings:
If the battery is not removed, it will be damaged by over-discharge and even catch a fire.

NOTICE

During the descent, if the course deviates, correct the rudder. If the wind is too strong, control the distance of the aircraft in the downwind area to prevent any unnecessary damage caused by the high wind. If the aircraft battery is low, prepare for landing in time. Do not exhaust the battery completely but keep a certain amount of power for re-flying in case of improper landing.
