Stock or Mod?

[BNT]

Hi all
I'm very keen on joining the SHRCCC fo 1/10 2WD racing - coming from 1/8 nitro and would like to experience a different class and driving style. In search of a decent buggy my top kit to buy atm is Yokomo YZ-2 which I'm gathering funds for.

With regards to the electrics I wish to ask what is the most popular to run - stock or mod - or do you run all 2wd in one class and let the yanks worry about the terminology?

I was looking at a orion 7.5t motor but not sure whats the norm out there.
Thanks for any help.
