Black Nighthawk Down:(

Just for information:)

I had motor position 4 on my 250 running twitchy, which i initially thought was that it was single phasing.

I put it on Cleanflight, which shut down every time i plugged the battery in to power up the motors. Turned out that fault was due to having my Bluetooth plugged in:)

I initially moved the motor on the Naze to position 1 and the fault stayed with the motor. On strip down i put my meter on the cable and only had continuity on two of the three phases(windings). On further inspection one wire snapped off.

Has anyone had experience of joining the wires again? It is an Emax 2204. Just curious as how to remove the windings?

Is it an external meaning outside the motor case or internal break? If it were external and me a little bit of twisting the wires together and a little solder then heat shrink to secure the bond
