Poncho, I have both twin and 4 motor planes, it can be rather confusing when you start setting up the tronics for 4 motors. twins are fairly simple

just the basics, you have to Y harness your ESC together and remove the power wire from one of them when doing twins, then Y harness your power leads for the batts to prevent one motor from cutting off

On 4 you have to Y harness 2 ESC together for each side then Y harness those together to go to the RX. you need to disconnect the red wire from each ESC.You also have to Y harness or just solder your batt leads together in each wing, then Y harness them into 1or2 connections for the batts. You will either have to use a UBEC or a flight pack for your RX as trying to run all 4 motors through 1 ESC would prob be certain disaster

In my SU-27 I use 2 ESC connected together and batt leads into 1 connector, I then use a 4 into 2 harness that allows me to use 3 batt packs to power it

In my Fat Albert look alike I have 4 motors Y together in each wing then Y inside the cargo bay to the RX the ESC power wires are soldered together in the wing and then connect to the same 4 to 2 harness allowing me to use 4 batt packs in it

to use a flight pack you just use a Y harness to connect the batt to the ESC via a servo lead

I hope this helped to at least get you going in the right direction
