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.
