DSLR for RC Photos, what to look for ?

[chris_dono]

Hi guys and gals,
As the title says, what should I look for in a DSLR for taking photos of RC Cars ?

I've not had an SLR before and I'm going to get one this year with the main purpose being to take some pics of this years' races and meets (both on and off-road)

I'm looking at the beginner ones at the moment (Canon 450 and Nikon 40/60).

Any sites with good info on photography in general would be much appreciated too ! I'm a complete newbie when it comes to this sort of thing, only having taken pics of nights out with a compact or a phone camera so far.

Thanks
Chris
