Default Newbie question: How do I hook up my motor cooling fan for power?

Should I just plug it into a spare receiver slot?

Yea depends on the fan. Some can run directly off the +/- of your ESC and some have to be plugged in to the Receiver with a receiver plug.

To save space on the receiver, I solder my transponder, glitch buster capacitor, and fan onto one receiver plug. Works perfectly.

for the cooling fan - My receiver has only 3 ports and all used it seems - don't see any male ends in there - do I have to add some male ends or ??? I bought the rc used and has the fan but I had to add my own receiver.

The better cooling fans run off direct battery voltage, more power to the fans for better cooling, also you can run into issues running fans off receivers, last weekend I saw two cars have receiver shut down issues from too much current draw through them.

My main cooling fan is actually soldered to the cap board off my ESC, which can be easier to setup that soldering direct to the posts on the ESC.

I've always preferred plugging mine into the receiver (using a 5V fan) as the BEC is maintained, where battery voltage varies each time you apply throttle.

A fan should never pull enough current to shutdown a receiver.
