thanks for the explanation suicideneil. hm does yout avatar come from that game 'my lil bastard' ? well i didnt see that rcu thread was that old

i do think its a bit misleading. as im more mislead than stupid of coz
I see the point in relating the 'rollout' to switching wheels, and also once i had a telemetry, to calculate speed (then i saw the interest in rollout). when thinking over it, both an esav and a pede has a stock 1:1 rollout, then that lead me to believe those trucks are designed like that. despite using imperial(inch) the 1:1 ratio seems to 'coincidentaly' ? work as a 1:1 guiding. why that is ? So it's just like that, the rc manufacturer puts on some kind of wheels (diameter) that relate to the gearing - or vice versa. well interesting. Because, the esav has brushed motors, the stampede has brushless motor.
im suspecting it has to do/inherit from standard dc motors ? take it further, relating to a standard kv-rating, or torque values..or something..? any idea why rollout 1:1 is what stock trucks have?
thanks for the pinon link, i would really like to not buy pinions there. i bought a few once, only to get the messages they're sold out, and whether i would like this and that instead. seeing how the MM XL is 'for sale' there and not in stock, instock and out of stock has its own meaning there.
the battery question was merely a theoretical question on the views of cell counts. I dont have any fancy idea of 8s on and e-savage dont even have an 8s esc to whip

But I do have an idea of an alza racing savage flux chassis with 4 x 2s and a leopard/toppower motor. (8s wont fit inside)
heres a funny pic (ooh, that why iphone charge so slow!)
I had a bad cell on 3s pack once, i can imagine a bad cell in an 8s pack would be terrifying annoying. where the 4 x 2s would leave 3 x 2s, thats the more 'practical' ideas i was thinking of. (like 2 x 2s could be used in 4 rc's, and fewer cells stacked in a pack) and maybe in an 8s pack, the 6 inner cells, those would be sitting like a can of fish heating up etc.. As i mention the lipo serial wiring was another matter itself (resistance and neatness). still, i dont see why some 10awg wiring resistance (multi-strand and all) would matter THAT much. it would also give some means of relocating 'weight'/CofG on a truck. like to adjust for wheelies and no-wheelies.
