Hi Chris,
Was good to chat, I handed you over the Darren and Chris then didnt see you again!
Echo most of what Mikey said by a 2wd motor at our track is 10.5 and then fiddle with the ESC settings to give a boost.
Apex Model's in Crowthorne stock most stuff, You'll get discount there as well! (James and Dean who were racing with us today work there) and they are the club sponsored shop.
Main thing is to go with your gut car wise. Lipo.motor wise, they'll all do the job
