also O'donnell is a very good buggy, and their new truggy will be great too. but i drove some Mugens this weekend and they are very good. but IMO you cant beat O'donnell, Mugen, or Team Associated. Losi is great and all but they take more maintenance, i like the way they handle and all that but i dont like how they wear faster than others, but thats probably why they handle so good. but if you get losi or mugen you will never have to worry about finding parts at the track.
