Hooking up 2 BEC without going thru RX

[rcs2022]

Need some Help Please!

Was trying to hookup my Servos to an External BEC without going thru the Rx, as i am planning on running the Steering servo on 7.2v and the throttle on 5.5v or 6v and both from external BEC's.

This is the Layout i have in mind, which I actually tried but it did not work?!?! any thing wrong i am doing?



If i opt to go thru the esc as per the layout on Brian Page, Script Asylum; What is the maximum amperage / current which the rx will handle. and how do i connect both servos?





Apologies if i am double posting again in a separate thread.
