Pre-flight preparation instructions (using remote control)

1. Aircraft frequency matching: Turn on the power of the aircraft and place it on a horizontal surface. At this time, the aircraft placed on the horizontal surface will automatically enter the frequency matching state, and the front white light and the rear red light will flash.
   Note: Set the aircraft in a correct direction, and the nose shall face forward. It must be placed on the horizontal plane.

2. Press and hold the power switch button of the remote control@)(step 1), and the power indicator of the remote control will be on; push the throttle lever up to top (step 2) and then to the end (step 3), code-matching will succeed, and the aircraft light will change from flashing to be always on.WARNING: The aircraft/remote controller must ensure sufficient power or it cannot take off.

3. Horizontal calibration operation:
   Press and hold the calibration button on the remote control¾-, the LED light on the aircraft flashes quickly. The LED lights on the aircraft are always on, which means the calibration is complete, and the remote controller emits a “beep” (Figure 1).
   Note: The calibration must be completed only when the aircraft is placed on a horizontal plane.

4. Start/stop
   Push the left control lever on the remote control upward (Figure 2). At this time, the aircraft can take off normally. After taking off, all the indicator lights of the aircraft will always be on. During the fiight, whether you short press the¾- key, the aircraft will stop flying (Figure 3).
   Note: This function operation is only suitable for the aircraft in an uncontrolled state. Under normal circumstances, it is recommended to use the one-key takeoff/one-key landing is, key.

5. One-key take-off and landing
   When the frequency matching is completed, lightly press the remote control “one-key takeoff/landing” button Js, (Figure 4), the aircraft will automatically rise to a height of about 1 meter, and keep fiying at this height; when this function key is pressed again, the aircraft will automatically land on the ground slowly.

WARNING
Operate the aircraft with the remote control. Before taking off, please operate according to the above sequence: Turn on (refer to 9.1)- frequency matching of the remote control starts (refer to 9.2)-horizontal alignment (refer to 9.3)-start/stop (refer to 9.4)- one-button taking off and landing (refer to 9.5)

Remote control method

When the left joystick (throttle) is pushed up, the rotation rate of the main blade increases and the aircraft rises.
When the left joystick (throttle) is pushed down, the rotation rate of the main blade slows down and the aircraft descends.

When the left joystick (rudder) is pushed to the left, the aircraft nose turns to the left. When the left joystick (rudder) is pushed to the right and the nose of the aircraft will turn to the right.

When the right joystick (rudder) is pushed up, the aircraft moves forward.
When the right joystick (rudder) is pushed down, the aircraft moves backward

When the right joystick (rudder) is pushed to the right, the aircraft fuselage deviates to the right.
When the right joystick (rudder) is pushed to the left, the aircraft fuselage deviates to the left.

360° roll

The aircraft can achieve 360-degree flight by the following joystick operation. In order to better perform the roll function, a height of about 1.5 meters shall be ensured between the aircraft and the ground. It is best to operate the aircraft to roll during the ascent stage, so that the aircraft can maintain the height more easily after rolling.

11.1 360° roll on the left
Short press the 360° roll button, then push the right joystick to the left, and the aircraft will flip 360° to the left accordingly

11.2 360° roll on the right
Short press the 360° roll button, then push the right joystick to the right, and the aircraft will flip 360° to the right accordingly

11.3 Roll Forward 360°
Short press the 360 tumble button, then push the right joystick upward, and the aircraft will turn forward 360° correspondingly

11.4 360° roll backward
Short press the 360° roll button, then push the right joystick down, and the aircraft will flip 360° backward accordingly.

Introduction of remote control function and operation

Headless mode

The front of the aircraft when the code-match ng is turned on is by default the front in headless mode; if it is necessary to adjust the direction, please turn on the code-matching again, and short press the remote controller “headless mode” function key (Figure 5). When exiting, please tap gently press this function key again & Special Tip Please make sure the aircraft is aligned with the straight line and let the gyroscope automatically detect the straight line, and the headless mode of straight line flight can be realized.

One key return
When the flying distance of the aircraft is too far, the aircraft can be recalled with the return function. When turning on the code-matching, the remote control must be directly facing the tail of the aircraft. During flight, press and hold the one-key home button( (Figure 6). When the remote control emits a “beep” sound, the aircraft will enter the one-key home function, and will automatically return to our side; when the joystick is operated in any form, the aircraft will be released from the home function. Speed switching
When the aircraft takes off, it is by default in the low-speed mode (3-geared switching); gently press the remote control by a “beep” sound for low-speed gear, two “beep” sounds for medium-speed gear, and three “beep” sounds for high-speed gear (Figure 7).

2. Blade deformation
   Installation error of AB propeller

|

1. Charge the battery

   The fan blades are printed with letters A and B. For fan blade A or B, replace the one that is broken.

The aircraft vibrates badly| Blade deformation| Replace the blade
Fine tuning is done but still can’t make the aircraft stable|

1. Blade deformation
2. Defective motor

|

1. Replace the blade
2. Replace the motor

After the impact, start the aircraft again and it fly uncontrollably| The three-axis acceleration sensor loses its balance due to impact| After leaving the aircraft for 5-10 seconds, or by the horizontal calibration, it will be ok.
