How to repair an Hubsan H107L X4 quadcopter

Some days ago, my Hubsan H107L X4 miniquad, from Banggood, stopped working: even if I connected a fully-charged battery, it didn’t move or light.

Therefore, I ordered from Banggood a flight control board (they call it receiver board) to replace the faulty one:

After having opened the quadcopter frame (fixed with three screws) and having unsoldered the old board, I started replacing it. First, I soldered the wires from the four motors and the four leds to the new board, with the correct polarity:

[checklist]

  • for the motors, the RED and WHITE wires are the positive pole
  • for the leds, the RED-enameled wire is the positive pole

[/checklist]

Then I secured the new board to the frame with two screws and – using a small screwdriver – I put the wires in the quadcopter arms:

After a final check, I closed the frame with the lower plastic cover:

Before being able to fly, I had to recalibrate the board as explained in the manual:

Salve, mi chiamo Andrea dalla provincia di Trento, premetto che le mie competenze elettriche sono vicine allo zero ma devo sostituire il corpo del mio Hubsan X4 poiché un braccetto si è rotto e non trovo nessun rivenditore nella mia zona che ripara l’X4, hai qualche consiglio da darmi?
Sono provvisto di corpo del drone nuovo, saldatore e stagno per saldatura, mi potrebbe servire altro?
Grazie.

ciao Andrea, la sostituzione è abbastanza semplice in effetti con un saldatore e un piccolo cacciavite hai tutto quello che ti serve
