I am just intending to buy a RC models for my brother as his birthday present from onlinshop, but I don't know much about that, so I want to look for tips from some relative forums. I enter here when I saw some keywords. Also, I haven't nocticed much about the regions, I think it doesn't matter. But I think that I made a mistake because the RC models here are professional and what I am looking for are just toys. I don't know the differences between them. Sorry for the troubles.
