I would suggest starting with 2wd first, Schumacher Cougar SV Pro 2011 spec, any KO or sanwa radio gear( make sure it's 2.4ghz), Speed passion or Hobbywing speedo, they are basically both the same but hobbywing would be cheaper.

I would also suggest going along to your local club to see what most racers are using, this way you would be able to get help with set up and spares should you need them.
