I see, so when the wire from the ESC is plugged into one on the channel sockets/slides on the RX it will power it also?.....or is there a seperate wire that goes from the ESC to the battery slide/socket ont the RX/?
thanks

It's not clear, and really confused me too!
The orange and yellow wires (I think that's the colours) from one side of the esc need to be connected together, think of these as a switch for turning the BEC on/off.
When connected it'll serve 5v down the red cable of the standard 3 pin pig tail, powering your Rx.
Don't connect both BEC's, you just need one.
And in case you didn't know (I didn't!), all the pins of the Rx will most likely be on rails (all + connected in parallel) so you don't need anything connected to the dedicated Bat port of the Rx.
The 3 servo wires can be seen as a + a - and a signal lead.
The BEC just uses the + and - to power the RX, and the 3 pins per servo lead just do the same. The electronics create a signal per servo lead pin, but the the 2 others are just common.
ok, so the yellow and orange cables get connected together....but where do they get connected to after that? the ESC has black, red, yellow, blue and orange cables I think?
so the cables get connected to where then?
red gets connected to positive on battery
black gets connected to negative on battery
Yellow gets connected to motor positive
blue gets connected to motor negative
small red wire?
small orange wire?
servo wire (i know that's easy it gets connected to rx)
Orange and Red wires you connect to each other.
Servo wire's connect to the Rx and that's it.
The power is sent down the + wire of the servo connector.
Also worth noting (you may already know) is that the yellow and blue wires don't have to be wired specifically to the positive and negative terminals of the motors, you just connect them up either way round and if your motor goes backwards when you press forward, you just reverse these connections.
Failsafes are either external units, in-built into the speed controller(s) (depending on model) or in-built to the transmitter/receiver (depending on model).
If you are using external failsafes, they just connect in between the white/red/black connector of the speed controller and the receiver. The same goes for the mixer; some will be labelled to say what plugs in where (usually 'Ail' and 'Elev') but again, you can just play around with what plugs go in where until your setup works.
I've never used external failsafes whilst using an external mixer but I think the failsafes get plugged in between the speed controller and mixer. Someone will probably be able to clarify if that turns out to be wrong though
does the spectrum transmiiters and receivers (2.4ghz) have built in failsafes?
also the ESC in the picture I showed with the BEC is 15A will this be enough for a featherweight running on drill motors?
