Dual motors & esc's

[Wetter]

can somebody please steer me to some info(tutorial) about setting up dual setups.
Thank you for your time.
ps i have been reading and browsing mostly what it takes to calibrate.( working in unison),
can not seem to find the info in detail.

a set of external bec's for each esc or one in a series or parallel wiring set up ?
just tryn' to make heads and tails of this,
i am probably making harder than it is.
i just need to see a diagram.
i found at Fighter Cat (Twin ESC Serial Wiring Diagram) but still need some help.
