Strongest brushless setup for revo?

[Over_revO]

I have no idea wich one is better :D
I want the fastest of them, one that you could gear for top speed for some runs and then run it geared for about 50-55mph.

If i can have batteries suggestions also could be great :)

Thx again for any help.

you wont need the 1521, I had a Revo I had geared 38/18 with 6s lipo and a 1515/2.5d it it could run around 50 mph and it was on the verge of being out of control. You could run 6s with a 1515/1y it would be faster but you will have a higher amp draw which will produce more heat
