If you are not sure yet, you could get some 4.4k top qualifier packs from maxamps, I have not run a full pack through mine yet but they give great power and i have run over 15 minutes with the mamba and haven't seen a drop in power yet

YEEESS !

I've finaly decided to go lipo !:018:
I've ordered 2st maxamp's 2s 8000mah pack an one 3s 8000mah pack :017:
Those pack's will make my rusty scream right ?:027: I've also ordered som smaller pinion gears for the 3s pack :017:

I think your Rustler should be doing more than screaming...

he he yea i think so to :018: !!!

How fast coud i go on 3s ? i have a mambamax 5700 combo in my rusty !
And how long runtimes can get on the 2s 8000mah packs ?

At lest 30 min depending on gearing.

WOW ! That's very nice to hear !:004:
my gearing options are :86T spur and 12,13,14,16,17,and 19T Piniongear. on 6-8 nimh cells i,ve beeen running with the 16T gear and on hardpacked surfices 19T.
I have ordered some masher 2000 tires choud i gear down to 14T on 2s and 12t on 3s ? the maximum temp that i've seen is 151F on the motor and 147F on the esc after som hard bashing on grass and gravel. i have a cooling fin for the motor that i'm going to mount this weekend.

if i lift the backwheels of the ground and hit the trottle the tires baloon's up to mgt wheel size !!:005:
