Default Wiring Fan for Cooling Brushless Motor

I'm going to wire a heatsink w/fan to cool my brushless motor. Do I just hook up red black wires to battery side of speed control?

Easiest thing to do if you have a unused slot in the rx is to run it out of there. If all the slots are used, get a y-connector and run it off one side. RXs usually have enough power to run most fans (unless its a really big one).

Yeah, you need to check the operating voltage of the fan. If it's a 5 volt fan it has to go off the ESC to last any time. I have mine on channel three.

I run mine off the third channel on the rx. When I was racing micro, many guys ran them straight to the battery. There cars sounded like they were ready to take off the fan was running so fast. I am not sure if the same applies to 10th scale. Just a thought.

Its a double fan. I might end up using just one. All my slots are filled up so I will try running a y harness in the slot I power amb transponder with. Thanks for suggestions.
