quark versus castle

[jollyjumper]

i'm very glad you guys like my question, please dig in deep.
i wanna hear all the good and bad about both.
a pro about the quark motors is they got a fan inside.
any one know how many poles those quark motors are?
if quark it is, 65 or 80 amp esc for t4?
the batts i'm lookin into are rated 64 and 74 amp continous.
of the motor's, any brushless motor, how can you know the amp draw under load?
cuz i believe amp draw will go up with higher gearing ( bigger pinion)? right?
on the quarks, there's a tread going on about thermal problems, do the 65amp and 80 esc's have those problems or is it just the 125 amp?
