AUX channel-> On/Off for Fan?

[Javage]

I'm wanting to use my AUX channel to turn on/off my fan. When wired up using 2 wires(neg/pos) it runs the fan fine, but I want to be able to switch it ON and OFF.

Is there any way to use the 3rd servo signal wire to make it so I can simply switch the fan On/Off via transmitter?

Radio is Speky DX3S, if that matters.

There is a way to do this. I just can't remember how. My Bro uses the 3rd channel to turn on/off light on his Baja. I will try to ask him how he did it and let you know, unless someone else beats me to it.

Savage: To switch the fan ON/OFF via AUX channel

and

RS4: To Switch LEDs ON/OFF via AUX channel

yeah i understand your tryin to control your fan, but I'm curious as to why you'd want to shut it off?

i assume your talking about the fan on the flux esc? is that right?

what is the benefit of turning it off?

Ok now we're on the same page. . .
I have a nitro with a fresh body, only hole is for the engine and would like to keep from cutting it up, so I'm trying out a fan idea- and would like to control the fan to see what kind of difference it makes.

RS4 same idea except use it for turning ON/OFF the lights.

you need to get a relay so that you can use your radio for the I/O do to the fan only has 2 wires (neg/pos) and the 3rd wire i believe is a signal transfer wire (not sure wat its called lol) but you would need a relay for it to work either way unless you run a seperate batt for the fan with a simple I/O switch

ya it kinda hurts when you have a custom painted body or something and have to cut it up!!

 

[Javage]

So what kind of relay should I look for?

 

[orcusomega]

Question - any way you could do a passive cooling system that would channel air instead of making something complicated and has the potential to fail with mud, sand, etc?

Just a thought.

You need a pico switch. It has a servo type pig tail and you wire your fan to the switch. Check sunkenmetals thread adding baja lights to a savage for pics. Wire your fan the same way. Sunks tutorial vvv

this is the switch you would need to make the fan work via the radio.

Picco switch looks good, but at $20 not sure if its worth it. . .

Also the size may be an issue(for the RS4, Savage will have plenty of room).
