Default Ends for Fans to go into the Speedo (ESC)

Can anyone point me in the direction of purchasing the ends to crimp on for a fan to plug into the speedo. I need to free up space in the RX and want to plug in the motor fan to the speedo fan port...

I have attached a picture to show you the connector...

You can always cut your connector off and extend the wired and solder it to your esc (+)&(-).

No, they are too big.

The wires for a receiver are usually 26AWG etc, the picture shows 20AWG.

Will have a look at work

It looks a lot like a JST-XH 2 pin, but it's too big. I gave up trying to figure it out. Also, the JST pin crimper is like $1200. Try digikey?

Generally motor fans are connected directly to the battery (at + and - on the ESC) to take advantage of the full battery voltage rather than the lower BEC voltage.

I read somewhere that the port is stabilised, whereas when you run mod motors and solder fans soldered directly to battery terminals, the fan slows down when you apply throttle.

I think the best option wouild be to cut the wires off a fan you aren't using and solder the wires with connector onto the new fan.

It's Rick Hohwart. I would go with what he's saying

I don't disagree there's probably some value in power stability supplied by a receiver, BUT i would like to share a problem I've recently run into with my rx-powered fan.

On my radiopost receiver, the fan turned out to be drawing so much amperage, it would inconsistently cause a total loss of control. I've since unplugged the fan and the problem went away. This didn't happen on my other car (which had a larger capacitor), so it was a pain to troubleshoot.

Direct hookup is definitely the way to go.
