Hi everyone. I just bought a scalextric for christmas for my son (yeah right). It is the 'micro scalextric power champions'. Just wanted to know if the 'micro' sets are a good starting point? My son is 8 years old. I have not tried it out yet because I have a slight problem- It was supplied with a 2 pin european type of transformer. Since I am in the UK I was wondering if this is standard? Is it safe to just use a travel adapter? Thanks you. Paul.
