Hi Matt, got your PM.

From what I've read, I reckon you've got a dodgy receiver. Several Radio Link units from Giant Cod have had the problem of the light being on on the receiver but nothing happening. My first receiver was fine until after the Edinburgh Robots Live event last year. When pressing the bind button on the receiver, the green light should flash for a few seconds until it picks up the transmitter and the it stays permanently on. But mine (and other people's) would flash for a good 30-40 seconds before staying permanently on, yet there would be no response when I moved the transmitter sticks.

If I remember rightly, the issue was a software fault in one of the receiver circuit boards (the receiver has a big main board that contains the pins that you connect your speed controllers too, and then a smaller board that mounts on top that the aerial is connected to). I can't remember which one, but people returning them to Giant Cod were being issued with replacements containing updated software and they seemed to work.

I bought a replacement just before this issue was discovered and it worked fine until it got flung out the robot at the UK champs. The only damage appeared to be that a PIC chip had broken free on one side but after resoldering it, it didn't work despite the green light coming on (though I can't blame it after taking such an impact). Since then I've yet to buy another receiver and see how that copes after an extended time, but in your case it may be worth seeing if Rob at Giant Cod will issue a replacement.

EDIT: A thread from the antweight forum documenting the problem: http://www.robotwars101.org/phpBB/viewt ... sc&start=0

so should i get a whole new unit then?

and i have been in contact with then young family :)

Try a new/different receiver first. In most instances the problem seems to have been linked to those rather than the transmitter.

where abouts in leicester are you based?

im in market harborough, about 15 miles or so outside leicester

Have those speed controllers got a BEC? I can't see it in the pic? There should be a yellow and orange wire coming from the same side the Power and Motor lead exit. Have you tried using batteries to power the Rx? Process of elimination and all that....

My Radio Link Rx just died, seems this is a very common problem.

When binding, how does the Rx know which Tx it is looking for? The Radio Link Tx has no binding button.
