Some may be thinking, “I’ve had my drone for so long and haven’t had any issues. Are will something bad happen soon??” Well, to ensure safe flight and keep your aircraft in optimum condition, it is suggested to perform thorough maintenance for your aircraft after 200 flights or flying for more than 50 hours. Below are some maintenance suggestions for the Phantom and Inspire series.
The Battery (We’ll use the Inspire’s battery as an example, but the same process applies to other models)
1. Check if there is damage or any deformities, such as swelling of the outer shell. If so, please stop using it and dispose of the damaged battery. Please do not attempt to disassemble the battery, as improper handling may cause it to explode.
2. Check the gold plates used to transmit data from the battery to the aircraft (shown on the right in the figure below). If they are stained on the surface, you can use a cue tip dipped in anhydrous alcohol to clean them to ensure good communication.
3. Check to see if the metal sheet inside the battery power socket (as shown on the left in the figure above) is damaged. If its surface severely burnt, use a piece of sand paper less than or equal to 1mm thick to polish the surface.
4. Check the cleanliness of the communication pins inside the battery compartment, and ensure they are clean, straight, and flexible to ensure a good connection. In addition, check the positive and negative power pins to see if they are ablated. If they are, use sandpaper to polish them.
5. Check the firmness of the plastic structure around the battery compartment. Look for cracks and tighten any loose screws to prevent the battery from coming loose during flight.
7. After powering on the aircraft and launching the app, you can check if the voltages of each battery cell are similar. If the voltages are consistent after being fully charged, but deviations between cells exceed 0.2V while above 3.7V, please contact DJI technical support for analysis.
2. Check the Transformation System (Inspire Series)
1. Check if the screw rod within the aircraft`s central frame is bent or damaged. The aircraft might not function normally if it is bended or damaged, and it will need to be sent back for repair if it is. In addition, check if the screw rod is rusted. If so, please clean it with rust remover in order to keep the aircraft fuselage from blocking transformation.
2. Raise the aircraft landing gear and check the cleanliness of the screw rod and the bottom bearing. If there is some dirt, they need to be cleaned and lubricated (WD-40 can be used as both a rust remover and a lubricator).
3. While the aircraft is entering or exiting the transportation mode, notice if the fuselage vibrates or there is any abnormal sound coming from the central rod within the central frame (like the sound of metal scraping on metal). Please place the aircraft on a horizontal surface while checking the transformation, with good illumination and on a flat surface. If the problems remain please contact with after-sales for help.
3. Check the Aircraft Fuselage
Inspire 1 Series Fuselage Check and Maintenance 1. Check if any fuselage screws are loose. If there are any cracks or damage arms please send your Inspire in for repair.
2. Check if the vibration absorbers are in good condition. If their exterior has solidified or cracked, please replace to avoid unwanted while filming and taking pictures.
3. Check if the white dampers of the landing gears are in good condition. The bottoms of the dampers should be fixed in place. If they are loose, apply super glue to stabilize them.
4. Check if there are any objects that will affect the signal attached on the top of GPS (like the sticker containing any sort of conductive material) and that there are no structural problems with the landing gears or anntennas (cracks, etc.).
Phantom 3 Series Fuselage Check and Maintenance
1. Check if any fuselage screws are loose. Also make sure there is no damage or cracks on the arms. If so, please have them repaired.
2. Check if the vibration absorbers are in good condition. If their exterior has solidified or cracked, if so, please replace them.
3. Again, do not attach conductive stickers atop the aircraft. This will affect signal reception of the GPS unit, the landing gear antennas, and compass.
That’s it for now everyone. In the future I’ll make another post about motors, propeller, IMU module and video downlink system maintenance.
