How hot? Do you have any means of measuring it?
Also, if its a brand new car, the diffs and motor can be a bit stiff to start with, which causes the drive to run less efficiently which causes the motor to strain and get hotter so it may be worth breaking it in a bit before worrying too much.
One thing worth mentioning is how good HPI are when it comes to returning faulty goods. I had a stock motor problem, sent it back with the ESC and within 5 days had a new motor and ESC foc.
