My own fault, I failed to apply some thread lock to the motor mount grub screws. I crashed and the resultant forces stretched and snapped the wires. I replaced the prop and it was still flying after the crash, just it was dropping an arm under full power. Shows why it is important to inspect your craft carefully after a crash.
And soldered together.
I have stretched out the wires as much as I can.
My motor now works fine after this repair. Not shown here but a safe bet is to make sure this will not short out. I secured and insulated it with hot glue.
