The motor you have is too fast for top drivers, let alone for a newbie, if your radio has the option of end point adjustment (epa) it will need to be turned down as it will be a bit quick
As for esc, I would advice a secondhand one, there are many good esc's available, you can usually pick up a Novak GTB, Lrp / Nosram for about £50-£60 which are very good esc's - just take a look in the forsale section
Speedpassion's are also very good escs and one can be found here for a good price, and I can vouch for the seller
