Brushless Combos

Are these good brushless combos for an E Revo?

And are these good lipo batteries for it? I would buy two for the E Revo.

I need my brushed Revo to go faster than 29... and go about 55 with this setup!!

hmm... i dont know... ive heard good and bad about em.. mostly bad tho, i probably wouldnt risk the brushless system, but the lipos are fine

I got the Mamba Monster and Zippy Flightmax 3S 5000mah 30C lipos.
