Using 4.8v & 6v UBEC's simultaneously

somewhere here i read how to wire 2 differing voltage ubec's for use at the same time to get 4.8v to the receiver and some servos and 6v to others. can somebody point me at a source of some kind? searching has been non-productive (not asking exactly the right way)
any directional input will be appreciated.

thanks to any and all,

Connect the 4.8V bec and those servos you want to run at 4.8V directly to the receiver, just as you would if the whole system was run at 4.8V.

On those servos you want to run at 6V, cut the positive power wire. Connect the signal and ground wires to the receiver as usual.

Connect 6V bec positive output to the positive servo power wire(s) which you cut in the previous step. On the servo side of the cut! Don't let the 6V power get into the 4.8V side.

Connect both esc grounds together. Done.

only one esc w/linear bec but, 2 ubec's. if the crude drawing is correct you'd think i'd have remembered how it's wired.

thank you for the help,
