the 7075 plate should be here thurs or fri

I have a cupple unanswered questions...
any recommendations on a CHEAP motor for it?? I'm thinking a feigao just to get me by for awhile...(witch one???)
if not a feigao then will something like a CC 4600, or a novak 10.5(13mm rotor) be up to running this beast

what I have...
whats the recommended wheel/tire?? 1/8 or 1/10?
what angle should I bend the sides of the chasis up? I know the more I go the stiffer it will get, but how stiff is too stiff...
since I'm making a custom motor mount, what distance should the motor shaft be from the top shaft on the tranny??
are there any slightly wider corr bodys that have the same wheelbase as the slash??
