If the ESC does not actually have BEC, (often referred to as an 'Opto' ESC), then a separate BEC or 4.8v supply, (4cell nimh etc), has to be used.

On all Rx's the +ive's are all connected together, same with all the -ive's, (at least to the best of my knowledge). So the supply to the Rx can be plugged into any spare channel, or even into any used channel via a 'Y' lead.

The ESC always has to be plugged into the 'throttle' channel.

If an ESC did have BEC, but wasn't powerful enough for the number of servos, a separate BEC can be used. BUT, the ESC's BEC should be disabled by removing the center terminal from the connector and insulating it, (red lead).
