Hmm... Either motor will be an excellent choice on 4s just gear accordingly.
Are you looking for speed or just bashing around?
I would only use the 1521/1.5D if you were bashing around. The D winds tend to be a little more demanding on the Amps and batteries. Like Lito said the 1515/1Y will be more than enough to push it around!
