Broke my own ESC

During practice my own very old SkyRC TS120A stopped working after a crash.

Very odd but something shorted during the crash and busted many of the mosfets and burned out traces on the PCB!



After replacing the mosfets and fixed the pcb trace it is running again.

It has been repaired before so the plastic housing was in very bad shape. It's been glued before and this time it felt apart.


I took a chance and ordered a Hobbywing XR10 pro case. It seems to be very similar.

Sure enough it was very similar but not a perfect fit.

The sensor port need to be enlarged


Some material inside the top part had to be removed to make room for the SkyRC power board

A little dremling here and there on the power board was also need.
Final result.
