Well I finally fixed the pcb!! I got the conductive adhesive stuff and thought yaay now this should fix it. But no. I carefully scraped off the insulating layer over the copper, applied the adhesive conductive stuff and carefully traced it back to the FIRMLY anchored wired (used a small screw to screw into the board - that sucker was going nowhere! Waited 20 minutes for the stuff to dry and switched on. The motor worked beautifully but no steering.
Much profanity, loss of some of the little remaining hair, and pain to the fist from hitting hard things. Carefully scraped all the gunk off the board to expose the copper again. Found a small thin piece of wire and tinned it, soldered it very gingerly to the bare copper and to the screw holding the wire into the board, and hey presto, magic happened and the steering now works. With great care I now screwed the pcb to the chassis so it aint never moving again. Tested and everything still working so now off for a celebratory glass of wine and come back to the build tomorrow with sanity restored. It could have been down to how I used the stuff but anyway I've got it for next time.
