Hi chaps and chapettes

Had a bit of a disaster on Friday. Ben was feeling a bit under the weather so we headed home early, but we weren't missing much racing anyway as we didn't manage to make a single lap of practice or heats .

As we headed out for practice the car didn't respond and I found a motor wire from the speed controller had come off.

Soldered it back on and got ready for heat one. Everything powered up but it wouldn't respond. Re-cycled the power and it came good, but then was hugely erratic in control, both steering and throttle.

It's an etroniks pulse radio set (with the blue receiver), only a few months old.

After lots of fiddling and checking wires I have found the following.

Seems to all work ok when tranny is right next to the receiver. As soon as you move it away it will work fine for a bit but then it will stop responding and the light on the receiver goes red. Sometimes this happened at short range, sometimes quite long range.

I have checked:
All plugs and wires.
Receiver aerial, both externally and opened up the received to see of there was anything loose.
Tranny, plenty of power and again I opened it up to see if anything was loose,
Like the aerial connection etc.
Tried rebinding
Tried the software reset on the tranny.
Tried unplugging the transponder.

Anybody got any ideas?
Could the loose wire have caused a power spike that had done something?
Should I send it back?
Shouldn't just try and buy a new receiver?
Has anyone had anything similar?

Thanks in advance.

We had a similar problem with an etronics, changed the recieved and it was fine

There's is a known problem with savox servos giving similar issues do you have a savox in ?

Andy,
Re-bind the receiver. Had the same issue when I set up my Xray, thought I'd bound it properly but when the car got about ten to twelve feet away the receiver turned red and the car just crawled along.

Failing that I've a spare blue receiver you can try.

Is it a sensored Speedo and motor? If so could be faulty sensor lead. I had it with mine, car act's like it has interference.

Thanks for all the answers, much appreciated.

I will try re-binding again tomorrow and see how that goes.

Matt wrt the sensor wire. As it's the steering that is affected too, does that rule this out?

Tried re-binding, but can't get it to work. Believe the process is:

Turn tranny on, then turn power on with the bind button held down.
The light should then go green.
I just get a sporadic flashing of the green light. Never goes solid green.

Yes i have a savox servo in it.

Tried binding with servo disconnected, but still nothing.

Think I have cracked it!!!!!

Don't ask me how, I just kept doing it, over and over, with different combinations of tranny and receiver power. After about 20 to 30 goes it seems to have worked.

Fingers crossed!
