Good afternoon, I have just unearthed a Micro endurance 7000. I have had since new so must be nearly 30 years old, it has a red and yellow mercedes and black and blue. I have set it up and it doesnt appear to work. not sure if its the TX, controllers or the cars. Is there anyway of purchasing spares for, I was thinking a new TX would be a good starting point? Thanks Ben
