well i bought an xray t2009 second hand last year and raced it all winter and the only thing that broke was the drive belt and i had a few hard crashes, the only real factor you have to think about is cost as xray spares are more expensive and alot more options to consider but having said that the i know people with schumacher's and they dont seem to have problems even bought my son an mi1 last year and he hasnt broke a thing on it and he is only 12 even won junior section last year with it and even beat some seniors, but xray is far nicer to look at
