III. Operation Guide
(I) Preparation before flight

Battery installation: The helicopter battery compartment is cleverly designed. When opening it, you need to follow the instructions in the manual, place your fingers in a specific position, gently press and push the battery compartment cover outward. Place the 3.8V 800mAh 20C lithium polymer battery in the battery compartment steadily, and pay attention to the positive and negative directions of the battery to be consistent with the markings in the battery compartment to ensure correct installation. After installation, gently close the battery compartment cover to ensure that the cover fits tightly and the battery is firmly installed.
Remote control setting: First, correctly install 6 AA batteries into the remote control battery compartment, paying attention to the battery polarity. After turning on the remote control, place the helicopter on a flat, open ground. At this time, the indicator light of the remote control may flash. By quickly moving the throttle stick up and down, the indicator light will become always on, and the remote control and helicopter will be bound. Then, pull down the dual joysticks of the remote control at the same time and push them to the right, hold for a few seconds, and calibrate the gyroscope. During the calibration process, the helicopter body will automatically adjust its attitude. After the calibration is completed, the accuracy of the flight attitude can be ensured.

(II) Flight operation

Takeoff: There are two ways to take off. You can press the eye-catching one-touch takeoff button on the remote control, and the helicopter will automatically and smoothly rise; you can also operate manually, pull down and push outward the two joysticks of the remote control at the same time, slowly and evenly increase the throttle, and then the helicopter propellers begin to rotate rapidly, generating strong lift, so that the helicopter takes off smoothly. During the takeoff process, you should always pay close attention to the helicopter's attitude. Once you find a deviation, you should immediately make fine adjustments through the remote control joystick to ensure that the helicopter rises vertically.
Flight control: During the flight, the four joysticks on the remote control can accurately control various actions of the helicopter. Pushing the left joystick left and right can realize the left and right turns of the helicopter; pushing the left joystick forward and backward can control the forward and backward movement of the helicopter; pushing the right joystick left and right can make the helicopter fly to the left and right; pushing the right joystick up and down is used to control the rise and fall of the helicopter. At the same time, make reasonable use of the fixed height function. When the helicopter is adjusted to a suitable height, press the fixed height button, and the helicopter will remain at that height, which is convenient for players to operate and combine various flight trajectories.
Landing: When landing, you can press the landing button on the remote control, and the helicopter will automatically lower the altitude and land smoothly according to the preset program. If you choose manual landing, you need to gradually and slowly reduce the throttle, while closely observing the helicopter's attitude, and fine-tune the joystick to keep the helicopter level and land smoothly at the designated location. During the landing process, be careful to avoid violent collisions between the helicopter and the ground to ensure a safe landing.

(III) Post-flight maintenance

After the flight, the helicopter battery should be removed in time. Since the battery will heat up during use, in order to avoid excessive discharge and overheating damage to the battery, after removing the battery, place it in a well-ventilated and dry place to cool naturally. Next, carefully check the appearance of the helicopter, focusing on whether the blades are cracked, deformed or damaged, whether the fuselage has collision marks, and whether the connections of various components are loose. Regularly use the screwdriver, hex wrench and other tools provided in the package to tighten the screws, nuts, etc. of the helicopter to ensure that the components are firmly connected and fully prepared for the next flight.
IV. FAQ

(I) Unstable flight

Cause investigation: Referring to multiple evaluation drafts, it can be seen that unstable flight may be caused by a variety of reasons. Uncalibrated gyroscope is a common factor. According to the feedback from actual evaluation operations, if it is not calibrated, the attitude of the helicopter is easy to get out of control during flight. For example, some players flew without calibrating the gyroscope, and the helicopter shook severely. In addition, strong wind in the flight environment will also affect stability. When the wind speed exceeds level 3, the helicopter flight will be significantly disturbed. In addition, insufficient battery power may cause unstable power output. When the power is less than 30%, the power will drop significantly.
Solution: You can recalibrate the gyroscope according to the steps in the operation guide. Choose an environment with wind speed less than level 3. Make sure the battery is fully charged before flying. When the power indicator shows insufficient power, charge it in time.

(II) Remote control signal loss

Cause investigation: If the remote control signal is lost, according to the analysis of the actual flight scenes of players in the evaluation, large metal objects, buildings and other obstacles between the remote control and the helicopter are a common cause. For example, when flying in an urban area with tall buildings, the signal is easily blocked. Insufficient battery power in the remote control may also cause unstable signal. When the power is low, the signal transmission power will be reduced.
Solution: Check the flight environment first and try to fly in an open area. Replace the remote control battery in time. If the above methods cannot solve the problem, it may be that the signal module of the remote control or the helicopter is faulty, and you need to contact after-sales for repair.

(III) Shortened battery life

Cause investigation: According to the evaluation feedback, the battery life may be shortened due to long-term use and performance degradation. Generally, the battery life will be significantly reduced after more than 6 months of use. Improper charging methods, such as overcharging or using non-original chargers, will also affect the battery life. Some players use non-original chargers, and the battery bulges and the battery life is greatly shortened.
Solution: It is recommended to replace the battery every 3-6 months. Be sure to use a dedicated USB charger and unplug the charger in time when the battery is fully charged.

(IV) The helicopter cannot take off

Cause investigation: First confirm whether the battery is installed correctly and has sufficient power. Some players installed the battery in the wrong direction, which caused the helicopter to be unable to power on. Check whether the remote control and the helicopter are successfully bound. Some players operated without binding, and the helicopter did not respond. Check whether the propeller is firmly installed and whether there is any foreign object entangled. In the actual evaluation, some players have been unable to take off the helicopter because the propeller was entangled with leaves.
Solution: Reinstall the battery correctly and judge the power status by observing the power indicator on the helicopter. If it is not bound, re-bind it. Clean the propeller foreign objects and reinstall the propeller. If the problem is still not solved, it may be a motor or circuit failure. You need to contact professional maintenance personnel for repair.
(V) The helicopter yaws severely during flight
Cause investigation: According to the evaluation experience, the pitch setting of the tail rotor is deviated, which will cause the helicopter to yaw severely during flight. If the tail rotor pitch is too large, the helicopter will deflect excessively to one side. Abnormal operation of the tail motor, such as unstable speed or abnormal noise, will also affect the flight direction of the helicopter. Uneven weight distribution of the fuselage can also cause yaw, such as mounting too heavy objects on the fuselage and the position is unreasonable.
Solution: Refer to the manual and use an Allen wrench to fine-tune the tail rotor pitch. If the tail motor does not work properly, it may need to be replaced. Check whether there is uneven loading of heavy objects on the fuselage, adjust the loading position or reduce the loading weight.

(VI) The remote control is not sensitive

Cause investigation: First check the battery level of the remote control. Low battery level may cause operation delay. When the battery level is less than 50%, the operation delay will gradually become obvious. Dust and debris accumulated inside the joystick will also affect the operation sensitivity. After long-term use, dust is easy to accumulate inside the joystick. The internal circuit of the remote control has poor contact. This may be due to the loosening of components caused by collision or long-term use of the remote control.
Solution: Replace the remote control battery in time. If the battery is normal, check whether there is dust and debris accumulated inside the joystick. You can use a clean cotton swab to dip a small amount of alcohol and gently wipe the inside of the joystick to remove dirt. If the problem persists, it may be that the internal circuit of the remote control is in poor contact and needs to be repaired.

(VII) The helicopter makes abnormal noise during flight

Cause investigation: Carefully check the propeller blades. According to player feedback in the evaluation, the propeller blades have cracks, deformation or wear, which will make abnormal noise during flight. If there are tiny cracks in the blades, high-frequency noise will be generated during flight. If there is a problem with the motor, such as overheating or abnormal friction, it may be that the motor bearing is damaged, which produces noise when running at high speed. If the fuselage parts are loose, such as screws and nuts, the parts will also produce noise during flight due to shaking.
Solution: Replace the spare propellers in time. If the motor bearing is damaged, the motor needs to be replaced. Use a screwdriver and Allen wrench to tighten each component to ensure a firm connection.

(VIII) The battery heats up severely during charging
Cause investigation: When using a non-original charger, its output voltage and current may not match the battery, resulting in severe battery heating during charging. From the actual charging evaluation of players, the battery temperature will rise rapidly when a charger that does not meet the specifications is used. Excessive charging environment temperature will also aggravate battery heating. When the ambient temperature exceeds 35℃, the battery heats up significantly. If the battery is aging or has quality problems, it may heat up severely even under normal charging conditions.
Solution: Be sure to use the dedicated USB charger that comes with the product. Charge in a well-ventilated environment with a temperature of 20℃ - 30℃. If the battery still heats up severely under normal charging conditions, the battery may be aged or have quality problems. Stop using it and replace the battery.

(IX) One-key takeoff/landing function fails

Cause investigation: First check whether the one-key takeoff/landing function is turned on in the remote control settings. Some players have turned off this function due to misoperation. Confirm whether the helicopter is within the effective control range of the remote control during operation. If it is beyond the control range, the function cannot be used. If all of the above are normal, the control module of the helicopter may be faulty.
Solution: Turn on the one-key takeoff/landing function in the remote control settings. Make sure the helicopter is operated within the effective control range of the remote control. If the function still cannot be used, it is recommended to contact after-sales for inspection and repair.

(X) Spare blade installation is difficult

Cause investigation: Before installation, if the spare blade model does not match the helicopter, it will cause installation difficulties. During installation, the blade installation direction is wrong and it cannot be installed normally. The installation hole may be slightly deformed due to transportation and other reasons, resulting in the blade being unable to be installed smoothly.
Solution: Make sure the spare blade model is completely matched with the helicopter. Pay attention to the installation direction of the blades. The markings on the blades should correspond to the markings on the helicopter hub. You can use tools such as needle-nosed pliers to adjust the hole position appropriately so that it fits tightly with the blade shaft to ensure a firm installation. After installation, gently turn the blades to check whether they are installed in place and whether there is any jamming.
