Just got hold of a faulty Wingsland M5.
On power on all it does is this:-
In App shows battery 0% and also no reading from sensors at bottom.
So first thought was maybe something loose inside or some power issue?
So teardown time 😉
Once I got this apart did notice something on the connector from esc board to main board , on the bottom right 3 of the wires were stripped bare and possibly touching when together? I noticed this before I took plug out, so I know it was not my own doing.
Above is the M5 esc board

Anyway, back to fault..
I have now checked all the mosfets in case they were to blame and all power rails seem to be fine.
Intresting I feel is the fact the app shows battery at 0% , but also the sensors have no value.
Camera works and records fine, so is there a problem with comms bewteen wifi and flight control data?
The R6 is connected and has solid blue light, but in app says disconnected, a clue there me thinks.
Anyway, off to fix those bare wires first as that could be related.
