receiver and esc

[N8CYL]

Hi, hope someone can help.

i have built an rc car from kit with no problems. I have now connected the ESC to the receiver channel 2 and the steering servo to channel 1. Battery connected via the ESC battery connector. Brushless motor connected by three wires from ESC.
When ESC switch in OFF position, the fan on the esc is ON. When switch ON the esc fan goes OFF. No LED lights show anywhere. No servo or motor power obvious.

What have I done wrong?

All help needed please.

Has the receiver got a power source to it?

Either the esc will have a small 2pin power out lead that will connect to the receiveds batt in.

Or you will have to use a seperate batt bor the receiver - normally a small 4xaa battery box comes with the radio gear

Nope, the receiver has four sets of pins: ch1, ch2, ch3, batt. Instructions show steering to ch1, ESC to ch2, no other pins to be used. ESC has leads to battery and three leads to the brushless motor.

had this problem before

its usually down to the different ways esc's are wired up

you will probably need to change the pins round on the plug from the esc to the reciver

have a look here :- http://www.jerseycoastrcclub.org/MembersArea/Train...

its about servos but esc's should be wired up the same

What esc and receiver have you got?

Make sure the ESC and servo plugs are connected to the receiver correctly.
The black (or brown) wire should be towards the outside edge of the receiver, the white (or yellow) towards the inside - at least, every receiver I've ever seen has been like this.

Some ESCs need the 3 motor wires connecting in a particular way, others just run backwards if connected the wrong way.

Hi, I have taken it apart again and re-connected and pressed the reset button on the ESC. Now the ESC beeps twice about every second and the red LED lights up. I have the connections correct. The motor leads are colour coded. The ESC goes into ch2 on the receiver and the servo for steering goes to ch1. The fan runs fast with switch ON and flat out when OFF !!
There is no make or part no except its an ACME brushless. The motor is a KV2080 and the ESC is a brushless 25A with Fan, there are no other codes/part no's at all. The receiver has no marks on at all.
Very frustrating.
Thanks

Apart from the advice above it looks like you may have to take it back to the shop.

I had to set up an electric brushless heli. and found that you needed to go through a set sequence to "programme" the esc for the motor.

This usually involved listening for a particular set of beeps, then performing an action to either change or alter the values....for example throttle top and bottom positions. (this was done by moving the throttle through a set range which would alter the value selected)

Suggest possibly looking for an instruction card that will show you how to "arm" the esc correctly?
