Tamiya's 501X is the best buggy they have ever built as far as competition goes.When you're up against the likes of BJ4's,XX4',ZX5's etc...you can forget the DF03,you'll need the 501X because this is the cars sole purpose.Save the bashing for the 'FUN' cars and run with the 501 I say.Im still yet to brake or bend anything on the 501 and Im running a 5.5 in mine.Only problem I have encountered is wear on the tyres
.GO TRF 501X!
