Why not let him try it out with the brushed motor before you start looking for a replacement? 17.5 brushless roughly translates to 27T brushed, so if the stock motor is too quick, try your other one before you get a new motor. That way you can compare two different winds, giving you a good idea of how "hot" any possible replacement should be.
If you already have your spending trousers on and an itch to buy something right now, get a spare battery.
