I have a 3 channel radio but need 4 things plugged in. Can I run the transponder and motor fan into a splitter on the 3rd channel?

Motor fan should be plugged into the ESC, not the receiver. Most ESC's have a port for the fan.

Short answer: yes.

Not sure I've seen a 3-channel receiver with only 3 ports, but yeah a splitter will work fine. Just make sure to use a decent quality one and watch for it getting snagged or working loose.

Some motor fans are happy to work off the battery directly, so consider that option too.

Yes,.4 way servo splitter in Toys & Hobbies for sale | eBay As long as other plugins aren't signal controlled. You can still use 3rd channel aux and other pug-ins are only dc powered.

My ESC fan plugs in to the ESC.....

nino.

Yes, of course.

There is absolutely no reason for the motor fan to be plugged in to the ESC (where do you plug in the ESC fan?), and both ports are supplied by the same BEC anyway.

Any reason why? Most of the time the ESC fan port is running off the same BEC output as the receiver.

my HW esc has a fan that only comes on when needed, idk if that works for the additional fan connectionbut i can imagine some might.

I've never ran anything that needed a fan on the ESC AND on the motor. Sounds like a lot of amp draw here and that I'm not familiar with.

Motor fans typically pull less than half an amp.

That I know, I was referring to motor amp draw. Must be running low turn motors on 2-3 cell or more?

Or they could just be running in high temperature ambient conditions. Around here pretty much everyone always runs a motor and ESC fan in the slow classes.

Also many people put high timing in their stock motors and gear them to the moon.
