Preparation Instructions Before Flight

Preparation instructions before flight(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. Turn on the remote control (default mode): long press the power switch button (step 1), turn on the power and the indicator flashes; push the throttle lever up to the top (step 2) and then to the bottom (step 3), and thus the frequency matching is successful, the UAV lights change from flashing to being permanently on.

_ Warning: _The aircraft/remote controller must ensure sufficient power or it cannot take off!

Horizontal calibration operation

• Long press the calibration key on the remote controller , and the LED lights on the aircraft will flash.
• When the LED lights on, calibration of the aircraft is completed, the remote controller emits “beep” (Figure 1).

Note: The calibration must be completed only when the aircraft is placed on a horizontal plane.

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 flight, whether you short press the 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 key.

One-key take-off and landing

When unlocking is complete, gently press the “One Key Takeoff/Landing” key on the remote control (Figure 4), the aircraft will automatically rise to a height of about 1 meter to maintain a stable flight; when you press this function key gently again, the aircraft will automatically land slowly.

Warning: Operate the aircraft with the remote control. Before taking off, please operate according to the above sequence: Turn on (refer to 10.1)→ frequency matching of the remote control starts (refer to 10.2)→horizontal alignment (refer to 10.3)→ start/stop (refer to 10.4)→ one-button taking off and landing (refer to 10.5)

Introduction Of Remote Control

Introduction of remote control function and operation

Remote control method

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.

• 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.
• 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.
• Roll Forward 360°
  • Press the 360° tumble button for a short time, then push the right joystick upward, and the aircraft will turn forward 360°correspondingly.
• 360° roll backward
  • Short press the 360° roll button, then push the right joystick down, and the aircraft will flip 360° backward accordingly.

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).

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.

Headless mode

The front of the aircraft when the code-matching 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 prompt: 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.

Fine tuning function

1. Fine tuning of aircraft moving forward/backward
   • When the aircraft leaves the ground and the aircraft deviates to the rear, press and hold ① forward fine-tuning key to fine-tune; when the aircraft deviates to the front, press and hold ② backward fine-tuning key to fine-tune.
2. Fine tuning of aircraft deviates to the left/right
   • When the aircraft leaves the ground and the aircraft deviates to the right, press and hold ③ left fly fine-tuning key to adjust, and when the aircraft deviates to the left, press and hold ④ right fly fine-tuning key to adjust.

Obstacle avoidance mode

During flight, short press Obstacle Avoidance to turn on obstacle avoidance mode (Figure 6). Thus, when the aircraft is close to wall or other obstacles in front/left/right direction, it will automatically move to a safe area it is in the obstacle avoidance function. If you want to switch to the normal fixed height mode, lightly press this key to turn off the obstacle avoidance function.

Note: Under sunlight or strong light, under transparent and reflective objects such as glass, and under black objects, the obstacle avoidance effect will become weak, or even lose its effect.
