(Step-by-Step Disassembly Manual)
Crashes are an unavoidable part of flying FPV drones like the DJI FPV Drone. The good news: most components are modular and replaceable. The challenge lies in the teardown process—this drone contains over 60 screws of varying sizes and types, making disassembly detailed and time-intensive.
This comprehensive repair guide walks you through safely disassembling and replacing nearly every major component.
Tools & Preparation (Before You Start)
Proper preparation significantly reduces errors and repair time.
Recommended tools:
- 1.5mm hex screwdriver (primary)
- 2.5mm hex screwdriver / Allen key (arm screws)
- Phillips 000 screwdriver (and smaller)
- Plastic spudger or pry tool
- Tweezers (precision required)
- Soldering iron (for motor wires)
- Magnifying glass or eye loupe
Pro Tip (Highly Recommended):
Organize screws using an A4 sheet. Secure each step’s screws with adhesive putty and label them clearly. This prevents misplacement and simplifies reassembly.
Key Disassembly Considerations
- Hidden screws: Some 2.5mm arm screws are inside the battery compartment and may be covered with adhesive. Remove carefully.
- Fragile connectors: Most connectors are press-fit—never force them. Proper alignment is critical.
- Micro connectors (LEDs & sounders): Always pull from the plug, not the wire.
- Soldered motor wires: These require desoldering—incorrect rewiring may reverse motor direction and cause crashes.
Step-by-Step DJI FPV Drone Disassembly
1. Remove Camera Cover
- Unscrew 4 screws securing the camera cover
- Gently pry it off
- Note: Clips on top and bottom must be reattached during reassembly
2. Remove the Canopy
- Remove 2 screws on each side
- Use a plastic pry tool to lift the canopy carefully
3. Remove the Gimbal
- Unscrew 4 mounting screws
- Remove 2 screws from retaining clip
- Disconnect press-fit connectors
- Peel back adhesive tape and remove gimbal assembly
4–5. Remove IMU Module
- Remove metal shield (2 Phillips 000 screws)
- Unscrew 3 micro screws securing IMU
- Lift module carefully
6. Remove Optical Sensor
- Remove rear-facing screws
- Push upward from underneath to release clips
- Disconnect ribbon cable (handle gently)
- Remove retaining clip and connector
7. Remove Bottom Cover
- Remove screws beneath optical sensor
- Unscrew front arm base screws
- Loosen (do NOT remove) 2.5mm arm screws inside battery compartment
- Slightly pull arms outward to release cover
- Feed ribbon cable through slot
8. Remove Rear Top Cover & Heat Sink
- Remove side screws and pry cover open
- Unscrew battery compartment base
- Remove heat sink (may detach easily due to thermal paste)
9. Access Antenna & Internal Components
- Loosen antenna retaining clips
- Remove clips and bug filter
- Disconnect U.FL antenna connectors if needed
10. Remove GPS Module
- Disconnect antenna connectors
- Remove fine screws (may require scraping coating)
- Remove retaining clip and connector
- Lift out GPS module
11. Remove Cooling Fan
- Disconnect fan cable
- Pry fan loose (secured with adhesive)
12. Disconnect Motor Control Board
- Desolder motor wires (12 total or 6 per side)
- Tip: Add leaded solder to ease melting of lead-free solder
- Remove board connector
⚠️ Important: Incorrect wiring will reverse motor direction and cause immediate crash on takeoff.
13. Disconnect Internal Connectors
- Remove screws near power connector
- Disconnect LED connectors under board (extremely small)
14. Remove Rear Arms
- Remove side screws
- Remove internal 2.5mm screws (previously loosened)
- Gently detach rear arms
15. Remove Front Arms
- Remove internal retaining screws
- Feed cables through battery compartment
- Carefully detach arms
16. Disassemble Arms
- Remove bottom covers (2 screws each)
- Disconnect:
- LED power cable
- Internal LED connector
- Antenna connector
17. Replace Central Battery Frame
- Disconnect sounder connectors
- Remove long and short screws (track carefully)
- Lift dual circuit boards (connected via heat pipe—DO NOT bend)
- Transfer sounders and wiring
18. Final Frame & Component Transfer
- Inspect for structural damage (arm stubs often break)
- Transfer GPS antennas (foam-mounted)
- Reinstall sounders and route cables correctly
Common Repair Mistakes to Avoid
- Forcing connectors → leads to irreversible damage
- Misaligned connectors → drone won’t power on
- Incorrect motor wiring → instant crash
- Poor cable routing → pinched or damaged wires
- Losing screw organization → reassembly failure
Final Thoughts
Repairing the DJI FPV Drone is entirely feasible with patience, proper tools, and careful organization. While the teardown process is intricate, following a structured, step-by-step approach ensures successful repairs and extends the lifespan of your drone.
