mambamax 4600kv and e-maxx q's ?

[speedy]

Hi !

How fast woud a rustler or T4 go with a mambamax 4600kv motor on 6cells and how fast on 3s 6000mah lipos ?
woud í get much longer runtimes with the 4600kv motor than with the 5700kv one ?
i'd like to de topspeeds of 45-60mph.


I have a e-maxx question also:027: if i put some pro-line crimefigter and velocety rims and 2st 2s 4000mah lipo packs in a e-maxx woud i get a very noteble preformance increase ?i think that woud drop 660grams of dead weight of a emaxx truck:017:
