Introduction

This tutorial provides a comprehensive step-by-step guide on how to replace the legs on the FIMI X8 SE 2020/2022 drone. If your drone has suffered damage from a crash, this guide will help you navigate the repair process, including removing old legs and soldering new ones in place.

Chapter 1: Removing Electronic Silicone and Solder

1. Disassemble the Drone

   • Remove the screws from the top of the drone.
   • Flip the drone over and take out the screws located on the bottom.
   • Be cautious as some screws may not unscrew properly due to broken plastic.

2. Remove the Silicone

   • Use a sharp pair of tweezers and an exacto knife to cut between wires and score the electronic silicone.
   • Take your time to avoid damaging any components beneath the silicone.
   • Heat the silicone slightly if necessary to make removal easier.

3. Document Wiring

   • Take a picture of the wire connections for reference when reassembling.

4. Remove the Solder

   • Clean the solder from the board using a soldering iron and a solder sucker.
   • Ensure the board surface is clean to allow for a smooth soldering process later.

Chapter 2: Back Leg Removal

1. Access the Back Leg

   • Unscrew any associated components that may be blocking access to the back leg.
   • Carefully pull wires through to remove the leg.

2. Inspect for Damage

   • Check for any additional damage to the drone's body and components.

Chapter 3: Front Leg Removal

1. Remove the Front Leg
   • Follow a similar process as the back leg to access and remove the front leg.
   • Ensure all screws and connections are safely detached.

Chapter 4: Prepare Solder Area

1. Clean the Soldering Area

   • Remove any residual glue or silicone from the soldering area.
   • Ensure the soldering tips are clean and ready for new connections.

2. Reconnect Wires

   • Prepare the wires for the new leg installation by checking their lengths and ensuring they are free of damage.

Chapter 5: Back Leg Install

1. Install the New Back Leg

   • Position the new back leg in place and secure it with the corresponding screws.
   • Solder the wires back to the main board, following the documented wiring.

2. Check Connections

   • Ensure that all connections are secure and wires are properly aligned.

Chapter 6: Front Leg Install

1. Install the New Front Leg

   • Repeat the installation process for the front leg, ensuring to keep all wires organized and secure.

2. Solder Connections

   • Solder the wires for the front leg to the board, following the documented reference.

Chapter 7: Put Back Together

1. Reassemble the Drone

   • Carefully align all parts and reattach any covers or shells.
   • Secure all screws and ensure the drone is properly sealed.

2. Test the Drone

   • Power on the drone to ensure all systems are functional.
   • Check for any firmware updates if prompted.

3. Calibrate the Gimbal

   • Make sure the gimbal is functioning correctly and calibrate if necessary.

Conclusion

Replacing the legs on the FIMI X8 SE 2020/2022 drone is a manageable task that requires patience and careful handling of electronic components.
