Hi El_xero,
Nothing wrong with being a noob
Yes, with 2 brushless ESCs you would use a "Y" harness to the throttle port on the receiver, with most ESCs you also must disable one of the ESCs BEC circuit, as they will conflict with each other, one exception I believe is Castle Creations. where both can supply power to the receiver, great if you have a lot of servos to power.
Now as far as the battery power with multiple ESCs, you can do it either way, you can connect one (gotta be big enough[X(]) to both ESCs in parallel, or use independent batteries, in many cases the physical layout may determine which is best.
Good luck,
Pete
Larry, I'm with you on the brushless motors, I gave up on brushed a long time ago, never looked back[8D]
