### 2.6 **System and withdrawal 2.6.1**  **of the aircraft structure demolition** ➢ UAV avionics bay and payload bay open, releasing the battery pack retaining screws, disconnect the battery and placed in the storage tank. The camera then remove the battery into the camera bag. ➢ Dismantling front wing pitot connection is disconnected withi n the first body, and then open the left and right wing quick release fittings, and slowly pull out around the wing, when the wing at about 50mm from the body, were left unplugged machine Wing steering gear control line, and the right wing servo control li nes, then pull out the entire wing. ➢ Open the left and right V-tail quick release fittings, and slowly pull out about Vtail, the tail from the body when at about 50mm, disconnect the left and right respectively V rudder control cables, then pull out the entire tail. ➢ UAV components shipped into the deposit box. **Note: Removing**  **the wings**  **and tail,**  **and the**  **tail section**  **of the**  **fuselage, be**  **sure to**  **slowly pull out, to prevent the pull control cables and pitot bad! 2.6.2**  **dismantling the ground station** ➢ We recommendafter the job is completed, the ground station interface cut every current notebook screen and save it to the time and place named later toTX- FW3 aerial unmanned aircraft systems operation and maintenance manual

### 3. **TX -** **FW3 aerial UAV system maintenance instructions**  **3.1 clean**  after each end of the flight, we need to clean the aircraft, mainly wipe debris, dust and grease aircraft surfaces require cleaning section includes: fuselage, wings, tail and so on. 

### 3.2 **Routine maintenance check** ➢ flights to check before airborne, ground station battery voltage is within the standard voltage range, if less than the standard voltage needs timely fill power. ➢ Check that t he propeller for damage, if damaged (especially the blade tip) need to be replaced. ➢ Check the fuselage, wings, tail look for damage. ➢ Check avionics system circuit is connected correctly. ➢ Check connector avionics system is reliable. ➢ Check if the load is working properly.TX- FW3 aerial unmanned aircraft systems operation and maintenance manual

### 4. **Other precautions**

● Do not move freely breaking rudder to avoid damaging the steering gear. ● Do UAV propeller by moving the body, as this may damage the propeller or motor, when moving the hand holding the bottom of the aircraft fuselage. ● When assembling the aircraft to ensure that quick release connector suitable tightness. ● Before flight to ensure that all appropriate connector, a connection error or a bad contact can cause serious equipment failure. ● Before departure to ensure that the machine hatch is installed, otherwise the device or task performed by the impact. ● Rechargeable lithium batteries require constant voltage charging, so the need for a dedicated charger. Do not use a poor contact charger, so as not to cause dissatisfaction and even damage the battery charging. ● When charging the battery, you need special care, to avoid overheating the charging cause an explosion or fire. ● Do not turn the key, coins, necklaces and other metal products touch the battery electrodes to prevent short c ircuits. ● Do not allow battery storage under higher than 60 °C or lower than

-20 °C environment. ● Once a battery swelling, leakage, or its temperature exceeds 70TX- FW3 aerial unmanned aircraft systems operation and maintenance manual

38 page °C, immediately stop charging it, or re

-use. ● When not used for long, lithium batteries should be pl aced in a cool dry place. Do not cut frozen, avoid moisture erosion. Avoid placing use in a high temperature area. Such as long

- term storage, the battery charge to 40% after placement. ● After giving the aircraft power, attention to hand when carrying out any operations not to enter into the propeller rotation plane, in order to avoid any misuse resulting in injury hand propeller rotation. ● Before departure to ensure that there is no damage and pitot tube blockage, or may cause serious flight accidents.
