Lego-kart racers

My son Lawrence races a go-kart which we prepare and mechanic ourselves at race meetings, I had an idea to create all the excitement of running your own remote controlled kart in miniature and so pitched the idea to Lego. Preparing your own Lego kart which you could customise and race on mini circuits around the country seemed a good idea that might appeal to kids who couldn't afford their own race kart. I also pitched a mini dragster racer based on the same lines.

They didn't respond to my pitch but I enjoyed
putting the proposal together
