When my mate and I did the upgrade in Phill's I too questioned him on the flat washer I cant say I was too happy about it but bowed to his superior Knowledge of the wee beastie. A word of caution however after nearly full assembly when we turned over the mechanicals there was a grinding noise and after a further strip down we found one of the magnets had detached itself. He re glued it and we re assembled. Phill and my mate went for a test in the upgraded three wheeler and I followed in Phill's it drove like a bag of spanners. When we got back I said it wollowed a bit in the corners and asked him to show us where they had been cracking, If my memory is correct he had already butt welded his own chassis but we found another crack that morning.Your cars are showstoppers guys but you need a sense of humour and a lot of patience to look after them.....
