So I'm using a Castle BEC Pro on my Trex 550.

The red positive wire from the ESC is cut in this configuration - so it does not provide power to the RX.

So the approx. 6 volts of power to the RX comes from the BEC. But why does it have 2 leads going to the RX??? Wouldn't just one suffice???

Is it just because of current capacity of the leads?

Saturday morning I flew my helicopter in my pajamas
How it got in my pajamas I'll never know

That's one reason. Another is that if there is a flaky connector, you still have at least one feeding the receiver. Cheap insurance.

Servo connectors can only handle 5A, that's why it has two. so it can draw up to 10A to feed everything.

10A continuous, 20A peak with two leads.

If youre thinking about using a Y connector, it will defeat the purpose of having two leads!
