xray is a good car no doubt, so is the losi.. but why buy something that is a copy when u can have the real deal? i bought the 808 tried it it was fast and i won a couple races with it does that make it good no not really lol.. i seen some stuff about it that needed improved and it was not quality. the losi was all around just great car just needs some improved metal and they have done that now. but now with mugen mbx6 out and the mp9 theres just to many cars out there that are fast.. and its all in setup any ways what works for one will not work for others... but i love the OD to its nice car. but if i was u id buy what is winning at your local track and go with it..
