waiting for the operator of the engine to the maximum delay of three seconds after 

pulling the trigger catapult launch aircraft, unmanned aerial vehicles took off. After 

hovering UAV launch stand in the air, ground station operators confirm that the 

system is working properly, click Job button, hovering UAVs will climb to operating 

height, then perform the job route.

Note: UAV autonomous takeoff ground crew and ground stations require operators 

together with the ground crew after the car pulled under catapult launch position, 

schematically ground station control staff catapult is ready, the ground station 

control officers received After the ground crew instructions, click on the button to 

take off, the engine is automatically adjusted to the maximum vehicle position, 

and motioned for the ground crew to lift car insurance, ground crew delayed three 

seconds after pulling the trigger catapult!

 To ensure the safety of flight, the UAV during operation, if the battery voltage 

drops below 21.6V, UAV command execution will start returning after the finish 

when the route in order to avoid excessive user-programmed set of routes, causing 

no Machine electricity shortage during the flight caused the accident,

circling overhead, ground stations and ground personnel in accordance with the 

operator to adjust the recycling route instructions until the ground operator 

acknowledges these can be used for recycling.

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 within 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 lines, 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!

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 the propeller for damage, if damaged (especially the 

blade tip) need to be replaced.

➢ Check the fuselage, wings, tail look for damage.

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 circuits.

● 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 70

38page

°C, immediately stop charging it, or re-use.

● When not used for long, lithium batteries should be placed 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.
