It would work only with the same motor (size/turns).

You do not need anything, just connect motor wires together and spin one motor shaft, another will follow. Then mark both shaft with permanent marker or make a scratch. Now you set to run them both from one ESC.

Do not worry about overheating, because now both motors will work half the previous load. But if you plan to push the limits you should select ESC based on twice the current ratings of both motors.

Dual BL from single ESC works the best with sensored setup. In sensoreless applications in some cases you will have problems with glitches on low RPM and start due to the fact of not precise matching of both motors. And motor shafts secure connection is the must.

Good Luck! Done that – Love it! You should to :)
