Motor spin with power applied scisky

when ever I plug in my scisky a constant 4.1v comes out of motor port s3 or motor 3 in CF and won’t increase or decrease throttle so it won’t fly I was thinking a fet but I am not sure I already bought a new board but I really would like to fix this board here is a pic plz tell me which part is broken if you know thanks!

FET is F*cked.

The FET for motor 3 is the 3 legged black rectangle in the lower left corner of the board.

how can you tell?

by the symptoms.
:wink:

cool should be easy to fix then right?

can’t find mosfet B12N

That’s just a lot code. Read this thread and you will learn all you need to know about replacing this FET:
