KO PROPO CX-III

Post by GWXP »

Hi, In need of a wiring diagram for this CX-III ESC

Only 3 wires coming from it and I am guessing it needs a jumper between one of the battery and motor wires but which one?

Any pics and guidance is appreciated

Usually a 3 wire esc has a battery - and battery + and a motor -. You would connect the esc to a battery + that also runs to the motor + a y or t connection

Ok,

So I'm going to assume;

Red is Battery +
Black is Battery -
Blue is Motor -

I need to jump from the red to the motor + ????

Any pics to confirm?

Thats the typical 3-wire setup. Not that it matters significantly, but I used to run a red wire from battery to motor, and tap the esc wire into the nearest point.

Ok, thanks

Another question, the small thin blue wire in the middle that leads to a small square female plus is what?

Outstanding support guys, thankyou so much.

After some soldering the CX-III powered up beautifully and runs like a charm.

It took some guess work on the top speed, neutral and power curve adjustments but it works perfectly!

Thanks again for the support..
