In the link you will see the game modes in black ops, I am pretty happy about them but they still didnt show the hardcore,barebones modes. The link also shows that there is a mode that lets you race the RC-XD.
i watched an interview with black ops developpers and there is no RC-XD game mode, they said it by themself. they also said that the race mode isnt an official mode but you can make races in private matches for console by turning off the exploding timing and that for pc, they think that modders will make this mod
There is no race mod. It was pulled off code of the leaked xbox version. But as far as the world is concerned at this point in time there is no race mode.
