Brushless

[GorillaMaxx360]

I was wondering... I wanted to get a Quark monster pro125B and a Lehner(LMT) 1950 motor. I was told this set up in a g-maxx would do about 45 but the price is like 600 dollars. So then i went to novak i saw there 4.5 brushless for just under 300 and in the introduction is says i does between 40and 45mph in an emaxx, but on the Novak spec sheet is says it does between 32 and 38mph. does any body know the actual speed of the 4.5 Novak brushless motor with 2 3300 stick packs. Also is the Quark lehner combo way better than the novak or is it just barly better. Is it worth the $300 extra bucks.
