I have bought many of these with the AM radio and they have been excellent at our track. But now with the 2.4ghz electronics, they are the greatest. They are soooo connected now and no more glitches or crystals. Now Kyosho's MR02 does look like an over priced car and radio combination. There is far better value for money with these. Not only are they cheaper but the radio alone puts others to shame. I have put the MR015 alloy front in mine with a rear motor mount and now I am running the Autoscale Golf GTI that is for the MR010. Well done, a great car. I will be back for more.
