The track looks excellent.
To answer your question, no dnano's aren't supported in this country at all.
Kyosho aren't all that big over here, people do own the RCs but the problem seems to be that there's always a question mark over getting spares as it seems not many places stock them. It's a real shame as they are a great company and sell some great models but for some reason or another shops are reluctant to stock them.
